2 mm long, obtuse or somewhat acute, yellow. Stamens 8, 10, or 
12, somewhat 2-seriate, one-half a little longer than the others, 
the longer filaments 2 mm, the shorter ones 1.3 mm long, subal- 
temate. Rudimentary ovary somewhat pubescent, oblong, about 
1 mm long, 2- or 3-cleft. Female inflorescence axillary, solitary 
or two in each axil, racemose 5 to 10 cm long, slightly puberulent, 
the pedicels about 5 mm long, each subtended by an oblong- 
ovate bracteole about 2 mm long. Flowers greenish, 5-, rarely 
6-merous, 8 to 12 in each raceme. Sepals 5, rarely 6, oblong, 
obtuse or acute, slightly pubescent, more or less recurved, about 
5 mm long, 2.5 mm wide. Disk annular, prominent. Stamens 
or staminodes none. Ovary narrowly ovoid, as long as or longer 
than the sepals, pale, densely gray-pubescent 3-celled, each cell 
with a single ovule; stigmas 3, rather stout, recurved, 3 mm 
long, apex slightly notched.

A species quite distinct from Cheilosa javanica Bl., but in many respects 
more closely allied to Alcinaneanthus philippinensis Merr., a monotypic 
genus recently described by me. The leaves have no basal, glands as in 
Alcinaeanthus, and the fruit, so far as can be told from old flowers, is 
evidently 3-locellate. It is decidedly intermediate in characters between 
Cheilosa and Alcinaeanthus, and goes far to invalidate the latter genus. In 
its male flowers being solitary in the axil of each bracteole, not fascicled, 
it is Alcinaeanthus, while in having 4-, 5-, and 6-merous male flowers it is 
intermediate between the 4-merous Alcinaeanthus and 5-merous Cheilosa. 
In its female flowers its 3-celled ovary is a Cheilosa character. In vege- 
tative characters it resembles both Cheilosa and Alcinaeanthus, more the 
former than the latter because of the entire absence of basal glands. Its 
specific name is taken from the fact that its leaves very strongly resemble 
those of several Philippine species of Homalium.
