Steven P. Churchill, Associate Curator, is working on a moss Flora of Colombia with support from the National Science Foundation (see Projects: Mosses). He recently published Prodromus Bryologiae Novo-Granatensis with co-author Edgar Linares C. (COL) and has compiled a database of nearly 11,000 records with the assistance of Angela Gómez (HUA); both of these efforts will provide the foundation for the Colombian moss Flora project. The project's long-term goal is a treatment of the tropical Andean mosses, a collaborative effort by various Andean bryologists and Churchill. A checklist for the mosses of the tropical Andes, co-authored with Dana Griffin (FLAS), is now being completed for publication. Another project nearing completion is A Guide to the Bryophytes of Tropical America, with S. Rob Gradstein (U) contributing the hepatics and hornworts (about 194 genera) and Noris Salazar Allen (PMA) and Churchill contributing the mosses (about 395 genera). Intended to promote and stimulate interest in these organisms, this illustrated guide will provide descriptions of all neotropical families and genera of bryophytes, as well as information on their diversity, distribution, ecology, and literature. Both an English and a Spanish version will be published. firstname.lastname@example.org
Thomas B. Croat, P. A. Schulze Curator of Botany, concentrates on the study of neotropical Araceae. Because of his efforts, the Missouri Botanical Garden has become a principal center of research in Araceae, with the largest collection of herbarium material and the most species-rich collection of living material in the world. A number of major revisions have been completed by Tom, including Anthurium and Philodendron for Central America, and complete revisions of Syngonium and Anthurium sect. Pachyneurium, all funded by the National Science Foundation. Floristic accounts for the Araceae have been completed for Nicaragua, Venezuela, Central French Guiana, Paraguay, Guyana and Hawaii, and florulas have been prepared for several species-rich tropical areas, including La Planada (Nariño) and Bajo Calima (Valle) in Colombia. The latter project was funded by the National Geographic Society.
Revisions of the genera Rhodospatha and Dieffenbachia of Central America, both National Science Foundation-sponsored projects, are nearing completion. Floristic accounts are being prepared for Ecuador, Veracruz (Mexico), and the Guyana region. Field work for a revision of Anthurium sect. Porphyrochitonium has already begun and, along with Richard Mansell (University of South Florida), work is progressing on a revision of Anthurium sect. Semaeophyllium. Other staff involved with Araceae include Michael Grayum, who has revised the Araceae for the Manual to the Plants of Costa Rica, as well as Philodendron subgenus Pteromischum and Guanghua Zhu, who has revised Dracontium and will begin work on other members of the Lasioideae, Montrichardia and Urospatha. Petra Malesevich, Senior Herbarium Assistant, coordinates most of the project work and manages various databases of Araceae. The living collection of more than 6,500 Araceae, managed by horticulturist Cheryl Neuman, along with its database, is the source of much new information on the biology and taxonomy of this diverse family.

Marshall R. Crosby, Senior Botanist and Senior Advisor to the Director, divides his time among various muscological projects, many of the activities in Scientific Publications, and special projects assigned by the Director. In muscology, he is coordinating the production of a worldwide checklist of the species of mosses. The checklist, now about 80% finished, is being compiled by the Garden's bryologists with outside contributions from specialists in some genera and families. It will contain an estimated 10,000 species, with geographical distribution indicated for each. The checklist will be published directly from data downloaded from MOST, the Garden's bryological database. firstname.lastname@example.org
Gerrit Davidse, John S. Lehmann Curator of Grasses, directs the Garden's participation in the Flora Mesoamericana project (see Projects: Mesoamerica). In this capacity he interacts frequently with Mario Sousa S. (MEXU) and Sandra Knapp (BM), London. An editorial meeting was held in London during June 1996. Davidse's research interests include monographic and floristic work on Poaceae and Cyperaceae. Current work continues to concentrate on the description of new taxa in connection with ongoing floristic projects. Two species of bamboos endemic to Colombia, Neurolepis silverstonei and N. petiolata, were recently published with co-author email@example.com
Calaway H. Dodson, Senior Curator, is working on a project to computerize information concerning the Orchidaceae of the world. This project will merge and edit existing databases and enter data and images that are lacking in those databases. At present, there are 57,000 orchid records in the database and it is considered to be relatively complete. Access to the database is available through the Internet in TROPICOS. The end product will be a catalog of the Orchidaceae that will contain a record for each published name, with pertinent information concerning author, literature citations, synonymy, present status, types and their locations, etc. Those records considered to represent valid species will contain information concerning exsiccatae (100,000 specimen records are now available), distribution, conservation status, original description, illustrations, and photos. Collaborators include Phillip Cribb (K), Robert Molly (CBG), John Atwood and John Beckner (SEL), Gustavo Romero (AMES), and Eric Hagsater (AMO). Dodson continues to coordinate the treatment of the Orchidaceae for the Flora of Ecuador. A CD-ROM version of Icones Plantarum Tropicarum with 2,400 illustrations and accompanying text has been prepared by Lightbinders, Inc. firstname.lastname@example.org

He is a member of the IUCN's Species Survival Commission special group for cacti and other succulents; other interests are the Vernonoideae (Asteraceae) and a variety of groups within the Centrospermae. email@example.com
Peter Goldblatt, Senior Curator and B. A. Krukoff Curator of African Botany, works largely on African plants and is a specialist on the systematics, biology, and phylogeny of the Iridaceae and related families of the petaloid monocots. His work is concentrated in southern Africa, an important center of evolution and diversification of petaloid monocots, including two-thirds of the estimated 1,800 species of Iridaceae.
Goldblatt has completed systematic accounts of the Iridaceae for Flora Zambesiaca (100 species, 1993), Flora of Somalia (six species, 1995), and Flora of Tropical East Africa (74 species, 1996), and for the Flora of Ethiopia (27 species, 1998). Working with J. C. Manning (National Botanic Institute, Kirstenbosch), Goldblatt has also completed a generic flora account for the Iridaceae of southern Africa now in press. Together Goldblatt and Manning have now completed a comprehensive florula of the southern African winter-rainfall zone, the Cape flora region. This part of the southern African subcontinent has almost half the total species of vascular plants that occur in southern Africa, about 9,000 species, some 69% of them endemic. All of southern Africa, about ten times greater in area, has some 21,000 species. In the New World, Goldblatt has completed accounts of the Iridaceae for Flora Mesoamericana, Flora de Nicaragua, Manual to the Plants of Costa Rica, and Flora of the Venezuelan Guayana. These treatments were prepared with J. E. Henrich (Denver Botanic Gardens). An account of the Iridaceae for Flora of North America is now in preparation, and Goldblatt has contributed several genera of the family.
Working in close collaboration, Goldblatt and Manning have an active research program, funded by the National Geographic Society, studying the pollination systems in the Iridaceae. They have completed studies of Lapeirousia (40 species) and southern African Gladiolus (165 species), both of which exhibit a wide range of pollination systems, including two novel systems involving different genera and species of long-proboscid flies in the horse fly (Tabanidae) and tangle-veined fly (Nemestrinidae) families of the Muscidae. These flies are the primary or sole pollinators of many species in both genera. The presence of these specialized pollinators and their associated guilds of plant species have permitted the diversification and radiation of species of several genera of Iridaceae, including into niches that apparently do not exist outside southern Africa. Goldblatt and Manning are also documenting several different guilds of plant species and their associated long-proboscid fly pollinators which have now been discovered across the entire southern African region. Three separate guilds of long-proboscid flies encompassing 14 species have been identified that are associated with different suites of plant species that occur in different parts of southern Africa or are active at different times of the years. The guilds invariably include two or more species of Iridaceae, often from different genera of the family, species of Pelargonium (Geraniaceae), and occasionally Amaryllidaceae, Orchidaceae, and Scrophulariaceae. Goldblatt and Manning are now extending their pollination studies to the genera Babiana, Hesperantha, Ixia, Romulea, and Sparaxis. The sub-Saharan African Hesperantha is particularly interesting, as different species exploit long-proboscid flies or settling moths for their pollination, the latter unique in the family, as well as nectar-foraging anthophorine bees, and scarab beetles.
Work on the systematics of the large genus Gladiolus was completed in 1998. A monograph of the genus in tropical Africa (83 species) was published by Goldblatt (Timber Press, 1996) and a second monograph, coauthored with Manning, dealt with 163 species in southern Africa. This work was released in 1998 (Fernwood Press, Cape Town) and included 144 sumptuous watercolor paintings. No sooner was the monograph published than two additional southern African endemics of the genus were discovered. Gladiolus has some 260 species, 250 in sub-Saharan Africa and Madagascar and 10 more in Eurasia. Southern Africa is the center of diversity of the genus and 160 of the 165 species that occur there are endemic, while tropical Africa has 76 endemic species of Gladiolus. The basic pollination system for the genus is one using long-tongued anthrophorine bees with nectar as a reward. Within the genus, frequent shifts in the pollination system have occurred, giving rise to pollination by sunbirds, noctuid and sphingid moths, long-tongued flies, a butterfly, and in a few instances, monkey beetles or short-tongued, pollen-collecting female bees. Comparison of the pollination systems with the infrageneric classification developed by Goldblatt and Manning suggests that at least 27 separate instances of a shift in pollinator have taken place. Goldblatt is working with Mark W. Chase (K), Paula Rudall (K), and Gail Reeves (K and NBG) on the generic phylogeny of the Iridaceae. DNA sequences of the chloroplast genes rbcL, rps4, and trnL-f have provided valuable data on generic relationships, and this will be combined with information from morphology and anatomy to analyze the family phylogeny. DNA sequences have shown conclusively that several African genera of the tribe Homeriinae are nested in the larger genus Moraea and accordingly have been sunk in that genus, leaving Moraea with nearly 200 species.
Working in close collaboration, Goldblatt and Manning have also published local wildflower guides for local regions in South Africa, and have a wildflowers guide, Fairest Cape Wildflowers, in press, that covers a large portion of the floristically rich Cape flora region. This work will be published in South Africa and will be distributed by Timber Press in Europe and North America. Goldblatt & Manning contribute regularly to popular journals that deal with African flora and natural history and have articles published in Africa and Veld and Flora. A manual of the extraordinarily rich bulbous flora of the Cape region was completed this year by Goldblatt, Manning and D. Snijman (National Botanic Institute, Kirstenbosch). The extensively illustrated work, dealing with over 1100 species of several monocot families including the Amaryllidaceae, Colchicaceae, Iridaceae, Hyacinthaceae, and some smaller families will be published by Timber Press in 2001.
Goldblatt is editor, together with D. E. Johnson (Timber Press, Portland) of the Index to Plant Chromosome Numbers, a project funded by the National Science Foundation. For this project, contributing editors throughout the world collect information on original chromosome counts published in the scientific literature, and the data is assembled in biennial indices published by the Missouri Botanical Garden. An Index covering the years 1994-1995 was published in 1998 and another for 1996-1997 is in press and is expected to be released in September 2000. Marie Johnson works part-time managing data entry and processing for the project. Plant chromosome numbers for the years 1984-1997 are accessible via the Internet through the Missouri Botanical Garden's W3TROPICOS firstname.lastname@example.org (Updated 5/00).

David Neill, Curator, has resided in Ecuador since 1985, where he has been carrying out floristic projects, providing technical training for Ecuadorian botanists, and assisting in the institutional development of the National Herbarium of Ecuador (QCNE), part of the Museo Ecuatoriano de Ciencias Naturales (see Projects: Ecuador). In the past Neill also has served as director of the Jatun Sacha Foundation, a private non-profit Ecuadorian organization engaged in conservation of natural habitats, biological research, and environmental education. Neill's taxonomic interest is in the bean family, Fabaceae. During the first half of 1997, Neill resided in St.Louis to work on the treatment of Fabacae for the Catalog of the Vascular Plants of Ecuador. An exciting event was the recent discovery of a new, undescribed genus of Fabaceae (Caesalpinioideae, tribe Detarieae), a large canopy tree now known from a few localities in the forest remnants of western Ecuador. The new genus will be published in the Garden's journal Novon. Neill is initiating taxonomic studies of the genus Lupinus in the high Andes of Ecuador. In the past year he has carried out field work jointly with Ecuadorian botanists from QCNE in various parts of the country and taught a course in biodiversity at the public university in Quito. His wife, Mercedes Asanza, is also a botanist and collaborates on various projects of the QCNE herbarium. firstname.lastname@example.org

Peter H. Raven, Director, is a member of the President's Committee of Advisors on Science and Technology, which is the highest level, private sector advisory group guiding the President on science and technology matters. Raven also continues to direct much of his efforts to the preservation of biodiversity, conservation of natural resources, and protection of the ecosystems of the world. His personal research program focuses on Onagraceae, a family on which he has worked for almost 40 years, and which, as a result of his work and that of many students and colleagues, is known in great detail. The main goals of the Onagraceae research program are to describe the relationships among species and genera using the precise definitions and methodologies of phylogenetic systematics, and to summarize in book form the overall features of the plants, their nomenclature, and the large body of literature on the family.
P. Mick Richardson, Manager of Graduate Studies (see Graduate Program), is interested in the evolution of secondary plant compounds in plants, especially higher plants. Cladistics has allowed our knowledge of these compounds to be used for taxonomic purposes in a more rigorous manner. The investigation of taxonomic congruence, especially the study of cladograms based on morphology with those based on the occurrence of phenolic compounds such as flavonoids, xanthones, and tannins, is another area of interest. Richardson has organized the Annual Systematics Symposium for the last few years with the invaluable assistance of Kathy Hurlbert and the Research support staff. firstname.lastname@example.org
Jon Ricketson, Curatorial Assistant, coordinates incoming collections for projects in Peru, Paraguay, and projects in Colombia.

Tatyana Shulkina joined the Garden staff in 1992 after a distinguished career at the Komarov Botanical Institute in St. Petersburg, Russia. While at the Komarov, she was Curator of the herbaceous plant collection from 1965 to 1984 and Curator of the entire living plant collection from 1984 to 1991. She also organized many field expeditions to collect plants for horticultural introduction and display in the garden. One of her major proj ects since her arrival in the U.S. is a study she is conducting on the flora of the former Soviet Union as a source of new ornamental plants. She is an expert on the Campanulaceae and ornamental plants of Russia and adjacent regions, and has a particular interest in the biomorphology of certain groups of plants. In 1997 she and James Solomon collected in the Caucasus region of the Republic of Georgia in collaboration with botanists from the Institute of Botany of the Georgian Academy of Science. At MO she has worked on projects in Onagraceae, the China Checklist, and the Peru project. At present she is coordinating the Garden's project in Paraguay. firstname.lastname@example.org

Peter Stevens. I have long been interested in the Malesian flora, especially that of New Guinea, and in phylogenetic/monographic studies (currently mostly in Clusiaceae, also Ericaceae). This study of plants is my first and continuing love. Monographic studies in several genera of Clusiaceae are well advanced, needing only blocks of time to finish final editing of generic treatments of Marila, Mammea, Mesua, Kayea, and Poeciloneuron. An extensive study of character variation and phylogeny in Clusiaceae s.l. is in a similar state. In Ericaceae, work focusses on Dimorphanthera (several new species), Paphia (perhaps reinstatement of the genus; new species with very interesting distributions), and Vaccinium (new species). Also, with Nancy Gift and Kathy Kron, a phylogenetic study of Kalmia and its relatives is almost finished. This work draws on experimental studies on character states and compares relationships suggested by different kinds of data; it has important implications for character evolution.
I am also interested in the history of systematic biology, especially the period 1750-1900, in systematic theory, especially the issue of data in systematics and delimitation of character states, and in the relationship between cognitive psychology and systematic theory and practice, past and present. These more theoretical and historical concerns are intimately linked to practice, hence work in one area often has implications in others. Thus debates over species limits in the 19th century mirror current discussions over species limits in the Malesian region. The main issue is under what conditions does the systematist see the discontinuities used to delimit species. Resolution of this issue has implications for biodiversity and ecological studies; in some genera the number of species we recognise may be wrongly estimated by a factor of two or more. Also, by following 18th and 19th century literature on natural history, zoology, and botany, we gain a very vivid idea of how these apparently innocuous words came to have—and still have—very different connotations for different groups of people. It is important to realise how trivial and unimportant the study of botany (= classification) had come to seem to many groups of people by the end of the 19th century!
In general, I am trying to understand just what it is that morphological systematists do, whether sight-identifying herbarium specimens or performing phylogenetic analyses. This understanding will help us improve our practice and clarify how the whole systematic endeavour relates both to other branches of biology and to the public at large. It is both interesting and sobering to see how often apparently quite different issues in the history of systematics and in current practice reduce to the problem posed by continuity and our attempts to solve it, which are all too often confounded by the fact that we have not fully realised the extent of the firstname.lastname@example.org (Updated 6/00).

Kay Yatskievych, has been a coeditor of the Flora of the Venezuelan Guyana since 1990. She edits and writes treatments and coordinates communications between herself, her two co-editors (Paul E. Berry, University of Wisconsin, and Bruce K. Holst, Selby Botanical Garden), and approximately 200 other contributors to the series. Kay designed the page layout for the 9-volume series, and has produced the camera-ready copy for the first five published volumes. The final four volumes are expected to be completed at the rate of one per year.
On her own time, Kay works on the flora of Indiana. Her Field Guide to Indiana Wildflowers, published by Indiana University Press, will be in print October 2000. It treats 1,564 species in 114 families--all of the herbaceous species (except grasses, sedges, and rushes) known from Indiana. It will contain 640 color photos, mostly taken by Kay and her husband George, and 376 detailed illustrations, all drawn by Kay. Her next Indiana publication will be A Catalogue of the Vascular Flora of Indiana, which will go to press in about one firstname.lastname@example.org (Updated 5/00).
Elsa M. Zardini, Associate Curator, resides in Paraguay, where she is working in collaboration with local institutions towards producing a floristic inventory and database of Paraguayan plants as part of the Flora del Paraguay project directed by Prof. Rodolphe Spichiger (G) and jointly published by MO and G (see Projects: Paraguay).
With the support of the National Geographic Society, Zardini and her colleagues have conducted an intensive collecting program that has stimulated conservation efforts. The Ybytyruzú National Park has been created in one of the mountain ranges surveyed, and plans are beingworked out to enlarge several other parks: Ypoá (95,000 hectares) to protect the entire lacustrine basin of Estero Ypoá (500,000 hectares); Cerro Corá to protect many of the table mountains of Amambay; and Defensores del Chaco, which will be joined to the Ka'a-lya National Park in Bolivia to establish a unique binational park protecting 5,000,000 hectares of the chaco. In addition to spurring conservation efforts, the information on Paraguayan plants gathered by Zardini and her colleagues is helping local landowners in their efforts to protect their lands.
Based on analysis of the collections made, on her former experience with the floras of Argentina and southern Brazil, and on recent publications, Zardini is developing the idea that the Plata Basin, which occupies 25% of South America, constitutes a floristic unit, probably the most diverse in substrates and plant communities in South America. This concept points towards a new interpretation of South American phytogeography. Commentaries related to this idea are appreciated (see e-mail below).
As part of Peter H. Raven's long-term program on Onagraceae, Zardini continues her monographic work on Ludwigia, and with Raven has submitted the treatment for Flora dos Estados de Goiás e Tocantins. The treatment for Flora del Paraguay is in preparation. Zardini will give a course at the School of Biology (in collaboration with the Head of the Botany Department, Bonifacia de Bertoni) and has lectured at the School of Graduate Studies (in collaboration with the Head of the Department of Environmental Studies, Blanca Masulli), School of Agronomy, Fundacion Moises Bertoni and Women's International Club.email@example.com
