288 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. 1H35 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 fi'uit 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^. 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.
