Pleurothallis fantastica Ames sp. nov. 
Radices fibratae, albidae, glabrae. Caules secundarii 
congesti, valde elongati, graciles, paucivaginati, superne 
leviter ancipiti, monophylli. Vaginae tubulatae, valde 
adpressae. Folium triangulari-lanceolatum, prope basim 
penninervium, usque ad apicem angustatum, apice mu- 
cronatum. Pedunculi abbreviati quam folium multo brev- 
iores, folio adnati. Pedicelli fasciculati. Flores sueced- 
anel. Sepala lateralia in laminam ellipticam connata. 
Sepalum dorsale anguste ellipticum. Petala late lanceo- 
lata, trinervia. Labellum carnosum, trilobatum; lobi 
laterales semiorbiculares, plus minusve erecti; lobus me- 
dius quadratus, papillosus, prope basim callo ornatus. 
Columna generis. Pollinia duo. 
Roots fibrous, whitish, smooth, about 1 mm. thick. 
Secondary stems 10-20 cm. long, about 1 mm. in diam- 
eter, crowded on a creeping rhizome, ascending, slender 
below, becoming slightly ancipitous above, but not so 
conspicuously so as in the closely related P. Tonduziana, 
clothed withseveral closely appressed, cylindrical sheaths, 
monophyllous. Leaves 10-17 em. long, 1.5—2.5 em. wide 
near the base, coriaceous, tapering gradually to an acute, 
mucronate tip, penninerved for the length of the adnate 
peduncle, the basal margins more or less involute. Pe- 
duncle about 2 cm. long, completely adnate to the leaf, 
bearing at the free end an ample sheath which is about 
6 mm. long and from which one to three or more non- 
resupinate flowers emerge in succession, only one flower, 
rarely two, being expanded simultaneously. Pedicels fas- 
ciculate, about 8 mm. long, smooth. Ovary 3.5 mm. 
long, Jointed to the pedicel. Lateral sepals connate, form- 
ing an elliptical lamina with eight nerves, 5 mm. long, a-
