BROMELIACEAE. INBio specialist Francisco Morales hit paydirt with his collection
number 12931, from 1300–1600 m elevation on the Atlantic slope of the northern Cordillera
de Talamanca between Tapantí and Tausito. This turns out to be Werauhia woodsoniana
(L. B. Sm.) J. R. Grant, new to Costa Rica and otherwise known (we gather) only by the type specimen,
from Prov. Chiriquí, Panama.
FABACEAE/FABOIDEAE. Former parataxonomist Reinaldo Aguilar continues to reel in the
big fish. Aguilar 6085, from the Sabanas Caracucha near Potrero Grande in the Valle de Coto Brus,
is the first Costa Rican record of Galactia glaucescens Kunth. This is one of those spp. that
appeared to skip over Costa Rica, having been collected from both Nicaragua and Panama. Another such sp.
is Lonchocarpus atropurpureus Benth., occurring in northern Mesoamerica, as well as Panama and
northern South America. But although the name has been long misapplied to Costa Rican material (beginning
with Standley in Flora costaricensis), no Costa Rican vouchers of the real L.
atropurpureus have been seen—until now! If you don’t know, now you know: the first
genuine collection of Lonchocarpus atropurpureus from Costa Rica is Aguilar 4984,
from the Península de Osa. Manual co-PI and Fabaceae specialist Nelson Zamora
(INB, LSCR) is responsible for both of the foregoing determinations.
ORCHIDACEAE. Oncidium luridum Lindl. [AKA Trichocentrum luridum (Lindl.) M. W. Chase
& N. H. Williams] was merely mentioned in the Manual Orchidaceae treatment (in the generic discussion
for Oncidium) as having been reported from Costa Rica in the literature, without a known voucher
that could be cited. Now the required voucher has materialized in the form of a recent collecion
(12866), from the Tortuguero region, by INBio curator Francisco Morales. As far
as we can determine, O. luridum was previously known form southern Mexico to Nicaragua, as well
as South America and the Caribbean. The name has sometimes (as in Flora de Nicaragua) been
synonymized under O. altissimum (Jacq.) Sw. Now for the bad news: on a recent trip to Panama,
Costa Rican orchidologist Mario Blanco (FLAS) collected (among other things)
Epidendrum guanacastense Ames & C. Schweinf. and Notylia pittieri Schltr., both of
which had been considered endemic to Costa Rica (the former in the Cordillera de Tilarán, the latter
in the Golfo Dulce region) and were so characterized in the Manual. Both determinations have been confirmed
by Manual Orchidaceae coordinator Robert L. Dressler.
