NEW OR NOTEWORTHY ORCHIDS 
slightly exceeding the lateral sepals, arcuate-porrect; basal 
part subquadrate, about 3.5 mm. long, 3 mm. wide; anterior 
portion ligulate-oblong, about 5 mm. long, 1.5 mm. wide, 
rounded at the apex, fleshy. Labellum minute, pandurate- 
subquadrate in outline, about 3 mm. long, including the 
very short membranaceous claw, 2.1 mm. wide across the 
slightly dilated basal portion, abruptly rounded-truncate at 
the apex, a pair of minute membranaceous auricles at base, 
lateral margins fimbriate, apical and basal ones shortly 
ciliate. Disc with a bilobed fleshy thickening in the center 
of the base, 2 high fleshy prominent keels run from below the 
middle nearly to the apex, 3-nerved. Column arcuate, about 
3.6 mm. long at the back, sharply dentate near the apex, 
concave in front, the lateral wings extending onto the fleshy 
concave foot which runs out onto the lamina of the lateral 
sepals. 
Pleurothallis hirsuticaulis is closely allied to P. scandem 
Ames, having similar though larger flowers; but it is widely 
different in its simple stems. It is vegetatively similar to 
P. Raymondii Reichb. f. 
This plant was described from a single herbarium 
specimen. 
Costa Rica, Province of Cartago, Vicinity of Pejivalle, 
Paul C. Standley & Juvenal Valerio 47052, February 7-8, 
1926. About 900 meters altitude. “On tree; flowers dark 
purple-red.” (Type in Herb. Ames No. 33372.) 
Pleurothallis Johannis Schltr. in Fedde Repert. 17 
(1921) 140. P. melicoides Schltr. in Fedde Repert. Beihefte 
19 (1923) 24. 
A careful study of the type specimens has convinced us 
that P. melicoides is so close to P. Johannis, both in vegeta¬ 
tive and floral structures, that it seems unwise to sustain it. 
Pleurothallis minuta A, & S. sp. nov. Herba exigua, 
caespitosa. Caules monophylli, vaginis tubularibus maxima 
pro parte obtecti. Folia elliptico-linearia vel oblanceolato- 
linearia, valde carnoso-coriacea, in siccitate subconduplicata.
