circiter 10; infructescentiis paniculatis, usque ad 15 cm longis, 
fructibus ellipsoideis, 12 ad 16 mm longis. 
A shrub or small tree, entirely glabrous. Branches and 
branchlets terete, brownish, grayish, or olivaceous, lenticellate. 
Leaves oblong, usually olivaceous, sometimes pale when dry, 
dull or slightly shining, verruculose on both surfaces, gradually 
narrowed below to the acute or acuminate base and more 
gradually narrowed upward to the rather slenderly acuminate 
apex, when young membranaceous, in age subcoriaceous, 13 to 
18 cm long, 4.5 to 8 cm wide; lateral nerves about 10 on 
each side of the midrib, irregular, prominent or rather prominent 
on the lower surface, obscurely anastomosing, the reticulations 
subobsolete or obsolete; petioles 5 to 10 mm long. Infructes- 
cences from the branches below the leaves, paniculate, up to 15 
cm in length, stout, the lower branches up to 7 cm in length. 
Fruits numerous, ellipsoid, smooth, yellowish-brown or brown 
when dry, 12 to 16 mm long. 
Samar, Catubig River at Mount Capatoan, Bur. Sci. 24382 Ramos (type), 
February 19, 1916, on damp forested slopes at low altitudes. Apparently 
referable here are Bur. Sci. 24847 Edaho, from the Catubig River, and 
Bur. Sci. 17565 Ramos from the vicinity of Catbalogan. 
Manifestly closely allied to Champereia manillana (Blume) Merr., from 
which it is readily distinguished by its longer, more numerously nerved 
leaves, larger panicles, and larger fruits. The leaf characters alone dis- 
tinguish it at once from Champereia platyphylla Merr., described above.

Apparently erect, said by the the collector to be about 1 m 
high, glabrous except the sparingly pilose younger parts and 
the inflorescence. Branches subolivaceous, longitudinally striate. 
Leaves oblong to oblong-elliptic, membranaceous, shining, sub- 
olivaceous, 15 to 20 cm long, 6 to 7 cm wide, subequally narrowed 
to the acute base and to the slenderly acute-acuminate apex; 
lateral nerves about 6 on each side of the midrib, curved-
