convex, with a long, acuminate, circinate tip which is invisible from 
above, being concealed by the apical margin. Column stout, 6 mm. 
long. 
The type from Gimogan River, Negros; where it was collected on January 5, 
1904, by E. B. Copeland (No. 134). — Growing in leaf mold in forests along the 
Baco River, April and May, 1905, R. C. McGregor (No. 308). — Terrestrial in 
humid forest at 700 ft. alt. along the Binabay River, flowers yellowish with purple 
spots, Nov. 3, 1906, Merrill (No. 5624). 
A careful study of the material collected by Merrill and McGregor in Mindoro 
leads me to believe that it is conspecific with the specimens collected on the 
Island of Negros by Copland and is not the same as Plocogloltis acuminata Bl., 
although a closely allied species. 
Plocoglottis mindorensis Ames sp. nov. 
Allied to P. javanica Bl. Plants 6-8 dm. or more tall, very slender, 
graceful, not much thickened at the base. Petioles about 2 dm. long. 
Leaf narrowly oblong-lanceolate, acuminate, very acute, tapering at both 
ends, about 3 dm. long, 2.5-5 cm. wide, smooth. Scape about 8 dm. 
long, pubescent, densely so near the summit, clothed at intervals with 
tubular, lanceolate, pointed sheaths. Bracts of the inflorescence rather 
rigid, triangular-lanceolate, acute, somewhat concave, pubescent, about 6 
mm. long. Flowers purplish, rather numerous in loose racemes. Pedi- 
cels slender, pubescent, about 1 cm. long. Sepals externally pubescent, 
the laterals falcate-lanceolate, about 12 mm. long, 6 mm. wide near the 
middle. Upper sepal oblong-lanceolate, 1.3 cm. long, about 5 mm. wide. 
Petals linear, falcate, obtuse, 11 mm. long, 2-2.5 mm. wide. Labell urn
