column-toot, free part of the blade broadly lanceolate, 
acute, 7-nerved, about 16 mm. long and 7 mm. broad, 
prolonged into a long mentum at the base which is closed 
almost to the column, mentum straight, slender, about

elliptic-lanceolate, acute, 5-nerved, about 16 mm. long 
and 7 mm. broad; lip long-clawed, the claw extending 
almost to the tip of the mentum, free portion of the claw 
linear, with a small recurved median callus near the base 
and two very small lateral lobes or teeth near the ex- 
panded portion of the lip, about 20 mim. long and 2 mm. 
broad, —-expanded part of the lip rotund or broadly sub-

Luzon: Province of Rizal, Sept. 1909, Loher s.n.; Province of 
Rizal, Sept. 1909, Loher 14709 (Tyrer in Herb. Ames No. 44653); 
Province of Rizal, Sept. 1909, Loher 14726 in part. 
In addition to the above specimens there is an un- 
identified slide in the glycerine collection in Herb. Ames 
which probably belongs to this species. It is 2/mer 17125 
from Luzon but the corresponding specimen has not been 
located.
