apex short-acuminate, margin distantly denticulate, glabrous, 
slightly shining ; lateral nerves 4 or 5 on each side of the midrib, 
prominent on the lower surface, the reticulations rather close, 
distinct; petioles pubescent, 5 to 7 mm long, with two small 
distinct glands on the upper surface at the junction with the 
midrib. Male panicles axillary and terminal, many flowered, 
pyramidal, slightly pubescent, up to 5 cm long. Flowers small, 
yellowish-white, the buds globose, 1.5 to 2 mm in diameter, in de- 
tail as in Alcinaeanthus philippinensis Merr. 
Luzon, Province of Laguna, San Antonio, Bur. Sci. 20586 Ramos, Feb- 
ruary, 1913, in forests. 
Manifestly closely allied to Alcinaeanthus philippinensis Merr. from 
which its differs chiefly in its comparatively small leaves. It is perhaps 
but a variety of that species with greatly reduced leaves.

This species is very common in thickets in and about Manila, and very 
manifestly is the form described by Blanco as Cansjera rheedii (non 
Gmelin), and as C. pentandra. The latter was compared to the former 
by Blanco, differing only in its 5, not 4, stamens. As a matter of fact 
Antidesma, rostratum Tul. = .4. pentandrum (Blanco) Merr. has 3, 4, or 
5 stamens, 4-merous flowers being much more common than are the 3- 
or 5-merous ones. The species flowers about Manila from April to 
July, and is locally known as bignay pogo; this name, however, is applied 
to several other species. Antidesma rostratum Tul. was based on specimens 
collected in or near Manila by Perrottet and by Baume, in Pangasinan 
by Callery, with reference to Cuming’s numbers 966, 1246, and 1316. 
Other than Antidesma ghesaembilla Gaertn. and Antidesma bunius Spr., 
it is the only species of the genus known from the vicinity of Manila. 
Cansjera pentandra Blanco was erroneously reduced by F.-Villar 3 to 
Antidesma cumingii Muell.-Arg., an entirely different species, as comparisons 
of the descriptions and specimens show. It is a sylvan form not found 
near Manila. Later it was reduced by myself 4 to Antidesma leptocladum 
Tul., due to the fact that I had erroneously determined a whole series 
of specimens as Antidesma leptocladum which are properly referable to 
A. rostratum — A. pentandrum. F.-Villar also reduced Cansjera rheedii
