Pleurothallis juninensis Sch/tr. var. subaequi- 
sepala C. Schweinfurth var. nov. 
Herba foliis magis oblongis acutis et sepalis subae- 
quilatis et sepalo dorsali ovato vel ovato-lanceolato a 
specie differt. 
Plant large, caespitose, up to 87 cm. tall from the 
base of the stem to the tip of an erect leaf. Stems 14— 
27.5 em. long, often stouter than in the type. Leaf 
ovate-oblong or elliptic-oblong, erect or widely spread- 
ing, shortly cordate at base, acute or short-acuminate at 
the apex, 10-11 cm. long, up to 3.5 cm. wide. Flowers 
bilabiate, brown or reddish. Dorsal sepal oblong-ovate 
or ovate-lanceolate, acute or acuminate, about 9.5-16 
mm. long, up to 5.4 mm. wide. Lateral sepals connate 
into an oblong-ovate or oblong-lanceolate lamina which 
is subequally long with the dorsal sepal and slightly nar- 
rower, acute or acuminate. Petals similar to those of the 
type. Lip similar to the typical form, oblong, rounded 
and minutely apiculate at the apex, scabrous, 5.1-6.1 
mm. long. 
This variety differs from the type in having the leaves 
broadest near or at the middle and especially in having 
the sepals more ovate or ovate-lanceolate with the dorsal
