ASCLEPIADACEAE. Marsdenia laxiflora Donn. Sm., collected and determined
by whiz-kid Francisco "Chico" Morales (4361), hails
from the oft-touted Hacienda Tiquires, in the Cantón de Acosta, southwest
of San José. It was previously believed to range from Mexico to Nicaragua.
ASTERACEAE. Continuing his diligent work with composites, bioprospector and closet
taxonomist Alexander "Popeye" Rodríguez informs us of
his own collection (2491) of Verbesina guatemalensis B. L. Rob. &
Greenm., from the foot of Volcán Miravalles. This sp. had been reported only
from Mexico to Nicaragua.
CANELLACEAE. A sterile specimen (Rodríguez 4682) from a sapling,
brought in by prospector "Popeye" from the intriguing Cerro Nara--in the
coastal range just southeast of Quepos--by look and taste happily confirms a new
locality in Costa Rica for this family. As yet undetermined to genus, this same
species was only recently discovered on the Osa Peninsula, that being the first
report of the family from Central America (see
Edge 4 (1): Jan. 1999). We await anxiously for flowering material, but
meanwhile have sent dried leaves to DNA stars Liz Zimmer and Yin-Long
Qiu, for their work on this and related families. We can breath somewhat
easier now that this repository of untold scores of information is known from
CONVOLVULACEAE. Ipomoea wrightii A. Gray, unusual for its filiform,
often spiraled peduncles, has been recovered by Manual co-PI Barry Hammel
from among material identified as Merremia quinquefolia (L.) Hallier f.
Although widespread and often cultivated, I. wrightii had never before
been found in Costa Rica. The collection, courtesy of parataxonomist/park guard
Ulises Chavarría (1046), is from
the edge of open woods in Parque Nacional Palo Verde.
Cyperus thyrsiflorus Jungh., previously known both to the north (Nicaragua)
and south (South America), can now be reported definitively from Costa Rica on the
basis of Gómez-Laurito 1307 (from near the mouth of the Río
Matina, near Puerto Limón) and Haber & Zuchowski 9606 (from
Monteverde). According to correspondent Jorge Gómez-Laurito (USJ),
to whom we owe this information, this is an apparently rare sp., very similar to
the better-known C. hermaphroditus (Jacq.) Standl.
MALPIGHIACEAE. Noteworthy rediscoveries, continued: another collection by
"Popeye" Rodríguez, this one from El Rodeo
(Rodríguez et al
3013), in the western Valle Central, is the first made in Costa Rica
this century (and just the second ever) of the mainly South American Mascagnia
stannea (Griseb.) Nied. The only previous Costa Rican record is the type of
Grisebach's basionym, an Anders Oersted collection from nearby Aguacate.
Just one other Central American collection of this sp. is known: Croat 24495,
the type of Mascagnia sericans Nied. subsp. buricana Cuatrec.
& Croat (see the Flora of Panama), from the Península de
Burica. Thanks to malpigh guru William Anderson (MICH) for the
determination, from a scanned image conveyed electronically.
MYRSINACEAE. Ardisia escallonioides Schltdl. & Cham., ostensibly
ranging from Mexico to Nicaragua, can now be reported from Costa Rica, on the
basis of a Francisco Morales collection from the afore-mentioned
SAPINDACEAE. Another of Chico Morales's pet
families yields dividends, in this case, two sp. of Matayba new to the
country: Matayba apetala Radlk., previously known from ± throughout
Mesoamerica (except Costa Rica) and the Caribbean islands, has been collected
from near Tilarán and in the Valle de El General; and Matayba
scrobiculata Radlk., reported essentially from everywhere that's anywhere
(Mexico to Brazil) in the Neotropics, except Costa Rica, can now be reported
from near Tilarán and our recent hot-spot, Fila Chonta (above Quepos).
VITACEAE. And finally, thanks again to (who else?)
Chico: Cissus anisophylla Lombardi, previously reported only from
Ecuador and Panama, is recorded alive and well in our all-time favorite, the
Osa Peninsula and nearby Fila Retinta in front of Palmar Norte, as well as
Quebrada Gamba, near Golfito. This is a new identification of several, relatively
old collections, first among them attributable to head-man at the MO herbarium
Jim Soloman (19262).
