ROBINSON. 
midrib about 20, evident on the upper surface, but not on the under 
surface. 
Type collected at an elevation of 1,950 ni on Mount Apo, District of Davao, 
Mindanao, by R. S. Williams, no. 2569, in flower and fruit, April, 1905. From 
it, it is impossible to separate DeVore cG Hoover 309, from the same locality, May, 
1903, although the leaves are smaller than in the type, furnishing the minimum 
measurements given above.

basi acutis, apicec breviter obtuseque acuminatis. 
Flowers fascicled in threes, borne on pedicels 3-5.5 m long, which
