MERRILL. 
smooth, black, about 8 mm long, slightly pubescent externally, 
ultimately becoming glabrous or nearly so, the pericarp leathery. 
Luzon, Province of Nueva Vizcaya, Dupax, Bur. Sci. 1H.35 McGregor, 
March, 1912, locally known as baliunasoy. 
A species well characterized by its leaves being densely pilose on the 
lower surface. Like most or all the species in the genus, the pericarp 
of the fruit contains a black resin. 
SEMECARPUS WHITFORDII sp. nov. 
Species S. cuneiformis Blanco similis et ut videtur valde 
affinis, differt foliis distincte acuminatis, paniculis dense pallide 
fulvo-pilosis. 
A small tree, the branches terete, brownish, slightly sulcate 
when dry, more or less pubescent. Leaves oblong-oblanceolate, 
thinly coriaceous, 14 to 24 cm long, 3 to 7 cm wide, narrowed 
from above the base to the acute, and usually distinctly inequi- 
lateral base, the apex distinctly acuminate, the acumen rather 
sharp, less than 1 cm long, the upper surface pale and shining 
when dry, glabrous or very slightly pubescent along the midrib, 
the lower surface rather pale-fulvous-pilose, the hairs rather 
short, spreading, more dense on the midrib and lateral nerves; 
lateral nerves 15 to 17 on each side of the midrib, prominent, 
spreading, anastomosing, the reticulations rather close, distinct; 
petioles 1 to 2.5 cm long, somewhat pubescent. Panicles ter- 
minal, ample, diffuse, about 25 cm long, the lower branches up 
to 12 cm long, the upper ones shorter, spreading, all parts rather 
densely pilose with pale-fulvous, spreading hairs. Flowers very 
numerous, 5-merous, more or less glomerate on the ultimate 
branchlets, sessile or subsessile. Male flowers 4 mm in diameter 
in anthesis. Calyx villous externally, shallowly cup-shaped, the 
lobes orbicular-ovate, obtuse, 0.5 to 0.8 mm long, prominently 
striate-reticulate, the reticulations dark-colored. Petals oblong- 
ovate, acute, pubescent externally, reticulate-striate like the 
calyx. Disk glabrous, shallowly 5-crenate. Rudimentary ovary 
very small, densely fulvous-villous. Filaments filiform, 3 mm 
long; anthers ovoid, 0.8 mm long. Female flowers and fruits 
not seen. 
Mindanao, District of Cotabato, Lebak, For. Bur. 1177 U Whitford, March 
4, 1912, in dipterocarp forests at low altitudes. 
A species similar to, and certainly closely allied to Semecarpus cunei- 
formis Blanco, from the typical form of which it differs in its distinctly 
acuminate leaves which are pale beneath but scarcely glaucous, and by its 
densely pilose panicles, the indumentum of a pale-fulvous color. It is 
apparently more closely allied to Blanco’s species than to any of the 
numerous forms recently described by Doctor Perkins.
