Habenaria (§ Mecosa) halconensis Ames sp. nov. 
Plant about 3 dm. high. Leaves much reduced, cordate-ovate to 
lanceolate, acute about 4 cm. long, 2-3 cm. wide, passing above into 
clasping lanceolate, acute bract?. Floral bracts exceeding the ovaries, 
lanceolate, - acute, about 1 cm. long. Flowers green, in a loose, erect 
raceme. Lateral sepals linear-oblong, acute, about 1 cm. long, 2.5-3 
mm. wide. Upper sepal broadly ovate, obtuse, 9 mm. long, about 6 mm. 
wide. Petals simple, lanceolate, falcate, obtuse, 8 mm. long, 4.5 mm. 
wide at base. Labellum simple, linear-oblong, tapering gradually to the 
obtuse tip, 11 mm. long, 3 mm. wide at base,-l mm. wide near the tip. 
Spur nearly straight, slightly CA'ceeding the labellum in length, 12 mm. 
long. (Uppermost flowers slightly smaller in all their pai-ts than the 
lowermost.) 
Terrestrial in open lioatli, at 8,000 ft. alt. on Mount Ilalcon, Nov. 20, 190G, 
Merrill (No. 5835). 
The material from which the ahove description is drawn is somewhat scrappy 
and not well provided with foliage. The flowers are much like those of Tlahcnaria 
angustata O. K., but considerably larger and different in detail.
