mountains mostly at altitudes above 1,000 meters, from northern Luzon 
to central Negros. The duplicates of most of the material from the 
early collections of the Bureau of Science were distributed as Homalanthus 
populneus Pax, which is a very different species. Homalanthus alpinus 
is always dioecious.

This distinct species was written up by me as a distinct species about 
ten years ago, but was never published, and the herbarium material, 
not very good, was later placed with Homalanthus fastuosus F.-Vill. The 
maximum size of the leaves is 15 cm in length, and Ahern’s specimens 
show all intergrades between this size and the smaller leaves on the 
type material, which are 6 to 7 cm in diameter. The female flowers 
have two very unequal sepals, both reniform, the larger one 2 mm 
wide and 1 mm long, the smaller one less than 1 mm in diameter. The 
stigmas are very strongly recurved.

Arbor parva 5 ad 10 m alta ramulis junioribus inflorescen-

A small tree 5 to 10 m high, nearly glabrous. Branches 
slender, terete, grayish, glabrous, the younger parts and the 
pedicels sparingly ciliate-hirsute with short, spreading, white 
or pale, simple hairs. Leaves opposite, chartaceous, rather pale, 
shining, and of about the same color on both surfaces when dry, 
entire, oblong-obovate, 7 to 12 cm long, 2 to 4.5 em wide, the 
apex shortly and bluntly acuminate, narrowed below to a width 
of from 6 to 9 mm, then distinctly cordate; lateral nerves about 
8 on each side of the midrib, rather prominent, curved-ascending, 
their axils glandular, the reticulations slender; petioles sparingly 
ciliate-hirsute, becoming nearly glabrous, 2 to 4 mm long. 
Flowers not seen, but pedicels of the fruits axillary, solitary, 
sparingly ciliate-hirsute, slender, about 2 cm long, the per- 
sistent sepals oblong, obtuse or acute, 5 mm long, two (or brac- 
teoles) accrescent, somewhat ovate, 5 mm long and 3 to 3.5 
mm wide. Fruits depressed-globose, about 8 mm in diameter, 
composed of three dehiscent cocci, the cocci densely covered 
externally with short, sharp spinelike processes which do not
