CYCLANTHACEAE.  Somehow, the key to Dicranopygium spp. got totally bungled, and even more amazingly, it took five years for anyone to notice!  That anyone was MO project coordinator Mary Merello, who pointed out that, in the first couplet, the leaf measurements given in the second lead contradict everything that comes thereafter.  Manual co-PI (and Cyclanthaceae author) Barry Hammel provides the following patch:

1   Láminas foliares bífidas por hasta ca. 4/5, los segmentos 1.5–2.5 cm de ancho, lineares...D. tatica

1’  Láminas foliares bífidas por 1/5–3/4, los segmentos (1.5–)2–15 cm de ancho, lanceolados a triangulares.

LECYTHIDACEAE. Having finished his Manual contribution, family specialist Scott Mori (NY) is now focusing on Flora mesoamericana, with immediate changes for us.  Scott has now decided that the name Eschweilera collinsii Pittier, synonymized under E. calyculata Pittier in the Manual, is instead an older name for E. longirachis S. A. Mori, which it now replaces.  For further information, see Scott’s Web page:


ORCHIDACEAERobert Dressler’s (CR) Manual treatment of Psilochilus separated two Costa Rican spp. provisionally designated as “sp. A” and “sp. B.”  According to recent annotations of MO specimens by one E. Rothacker (OS), material (including the Manual voucher) previously determined by Dressler as Psilochilus sp. A corresponds to Psilochilus carinatus Garay.  The Manual voucher of Psilochilus sp. B is annotated by Rothacker as P. modestus Barb. Rodr.; however, a second specimen determined as sp. B by Dressler, from virtually the same site, is annotated as “Psilochilus sp. c.f. physurifolius” (Rchb. f.) Løjtnant by Rothacker.  So it may be that we have three spp.!  And this just in:  we have been made aware that the spelling Pescatoria is apparently correct (we’ve not checked the original literature), not Pescatorea, as used in the Manual—and every other major regional floristic work from Standley’s Flora of Costa Rica (1937) through Franco Pupulin’s Catálogo revisado y anotado de las Orchidaceae de Costa Rica (2002).

POACEAE.  During her recent visit to INB (see under “News and Notes”), bamboo specialist Lynn Clark redetermined the Manual voucher for Guadua macclurei R. W. Pohl & Davidse as Bambusa vulgaris Schrad. ex J. C. Wendl.  This in no way implies the loss of the sp. from the flora, as one of the isotypes, Pohl & Calderón 10103 (MO), is from near Piedras Blancas; however, the “Pen. de Herradura” locale should be deleted.

ERRATA:  We have a lot to report here, due mainly to the hasty preparation of our last issue immediately prior to PI Grayum’s departure for Costa Rica (see under “News and Notes”).  Most of our snafus involve the review of the paper by Blanco et al. (see under “Germane Literature” in our last issue) dealing with the generic classification of Orchidaceae subtribe Maxillariinae.  The final paragraph of the review enumerates five binomials in Maxillaria that were accepted in the Manual, but were “apparently unacounted for in [the] new system.”  In fact, the authors have accounted for all of these, as tactfully communicated to us by first author and Manual correspondent Mario Blanco (FLAS), in the following manner:  Maxillaria cacaoensis J. T. Atwood is indeed considered a synonym of M. mombachoensis A. H. Heller ex J. T. Atwood, as we had wondered, though this was not indicated in the paper; Maxillaria longipetiolata Ames & C. Schweinf. was transferred (p. 525) to the new genus Mapinguari Carnevali & R. B. Singer, which we erroneously stated “apparently [does] not occur in Costa Rica”; Maxillaria muscoides J. T. Atwood was mentioned (p. 517) as an anomalous sp., for which generic assignation was withheld pending DNA analysis (Mario speculates that it will fall into Maxillariella); Maxillaria piestopus Schltr. was synonymized (p. 535) under Sauvetrea laevilabris (Lindl.) M. A. Blanco, Sauvetrea being another genus we had indicated as apparently absent from Costa Rica (though Mario questions the provenance of the only two Costa Rican specimens); and finally, Maxillaria quadrata Ames & Correll, a nomen novum based on Ornithidium lankesteri Ames, was transferred (p. 520) to Camaridium as C. lankesteri (Ames) M. A. Blanco.

Our brief review of the paper by Duno de Stefano et al. was sufficiently long to incorporate a grievous error.  We supplied a URL for the on-line journal Vulpia, while noting that it “hasn’t worked for us.”  The reason is that we somehow bungled the URL!  Here is the correct version:


Many thanks to Alexander Krings (NCSU) for pointing this out.  Maybe if we’d noticed the North Carolina State connection, we’d have seen the light!
