and lateral nerves more or less ferruginous-pubescent. Branches 
terete, brown, eventually glabrous. Leaves coriaceous, glabrous, 
olivaceous and shining on the upper surface when dry, the 
lower surface brown, midrib and lateral nerves rather densely 
pubescent with short hairs, 10 to 15 cm long, 4 to 5.5 cm wide, 
apex rather abruptly acuminate, base rounded; lateral nerves 
about 11 on each side of the midrib, very prominent on the lower 
surface, anastomosing ; petioles prominently rugulose when dry, 
pubescent, rather stout, 7 to 10 mm long. Staminate flowers in 
axillary fascicles, their pedicels 1.5 to 3 mm long. Sepals oblong- 
elliptic, rounded, 3 to 3.5 mm long, densely cinereous-puberulent 
externally. Petals oblong-spatulate, apex rounded, base long- 
narrowed, densely ferruginous-villous, about 4.5 mm long. 
Glands oblong, glabrous, 1 mm long. Staminal column 5 to 8 
mm long, shortly stipitate, much narrowed below, densely fer- 
ruginous-villous ; anthers 8, about 1 mm long, their short free 
filaments densely villous, 1 mm long or less. Arms of the rudi- 
mentary ovary slender, glabrous, about 1 mm long.

Trigonopleura borneensis is the third species for the genus, one being 
known from the Malay Peninsula, and one from Mindanao, Samar, and 
Leyte in the Philippines. The form above described is very distinct from 
the other two, well characterized by its leaves being pubescent beneath, 
with more numerous lateral nerves; its spatulate petals; and its staminal 
column distinctly thickened upward, not cylindric.

Opportunity is here taken to adjust the synonymy of the Philippine 
species, as it was nearly simultaneously described both by Mr. Elmer and 
by me; Mr. Elmer’s specific name being the older, is here adopted. 
The material on which Alsodeia dubia was based presents only staminate 
flowers, but it is Trigonopleura, not Alsoidea, and matches Trigonopleura 
philippinensis Merr. in all respects. While placed by Mr. Elmer in the 
Violaceae, it is evident from his statement regarding it that he was very 
uncertain as to its true position: “Rather uncertain as to the right family 
and may possibly belong to Flacourtiaceae or rather to Icacinaceae."

Borneo. Those previously credited to the island are as follows: Bauhinia
