An erect, much-branched shrub 3 to 4 m high, glabrous except the 
branchlets and young leaves which are somewhat pubescent. Branches 
stout, terete, yellowish- or grayish-brown, the branchlets puberulent, 
slender, most of them terminated by a short, 1 to 2 mm long spine. 
Leaves alternate, mostly somewhat crowded, elliptic-ovate, coriaceous, 
1 to 1.5 cm long, 5 to 10 mm wide, acuminate, base acute, margins rather 
densely crenulate, each tooth, in young leaves, bearing a small, oblong, 
brownish gland, which is early deciduous; nerves 2 to 4 on each side of 
the midrib, ascending, distinct beneath, the reticulations also very distinct 
on the lower surface; petioles 3 to 5 mm long; stipules acicular, about 
2 mm long. Flowers axillary, fascicled, the pistillate ones 4-merous, 
their pedicels 2.5 to 4 mm long. Calyx 2.5 to 3 mm long, the lobes 
narrowly ovate, somewhat acuminate, about 2 mm long, 1 mm wide, 
slightly recurved, obscurely keeled within. Petals none. Ovary ovoid, 
glabrous, 2-celled; style 1 mm long, cleft, the arms 0.5 mm long, 
recurved. Staminate flowers unknown. Fruit ellipsoid or narrowly 
obovoid, black and shining when dry, blue when fresh, about 6 mm long 
(immature), the persistent calyx-base 2.5 to 3 mm in diameter. * 
‘ In the mossy forest, altitude about 2,400 m, For. Bur. 18102 Curran, Merritt, 
' & Zschokke, January 6, 1909. 
_A species allied to the Asiatic Rhamnus virgatus Roxb., and R. dahuricus Pall., 
and to the Japanese R. japonicus Maxim., but apparently sufficiently distinct from 
all described forms of these.

Rather widely distributed in Luzon; India to southern China and Japan. The 
specimens cited above belong to the variety hancei Planch.

This species seems to be imperfectly known, but the specimen cited above 
apparently agrees closely with the plate in Wight’s “Icones” cited by Planchon. 
This form is widely distributed in the Philippines; Sumatra.
