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 6 

 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 

 Le'yte 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
