DinaAGat, Bur. Sci. 35218 Ramos & Pascasio, May 11, 1919, 
in forests at low altitudes. Bur. Sci. 35076 Ramos & Pascasio, 
from the neighboring island of Bucas Grande, undoubtedly rep- 
resents the same species; this number differs from the type 
in having its leaves somewhat pubescent beneath. 
A species well characterized by its coriaceous, lanceolate, 
rather few-nerved leaves, which attain a length of 30 cm and 
are from 3 to 6 cm in width.

A shrub, 3 to 5 m high, glabrous except the inflorescence. 
Branches grayish or brownish, terete, the branchlets somewhat 
compressed or sulcate. Leaves when dry rather uniformly 
blackish, and shining on both surfaces, subcoriaceous, oblong to 
oblong-elliptic, 10 to 17 cm long, 4 to 7 cm wide, subequally 
narrowed to the acute or acuminate base and to the distinctly 
acuminate apex, the acumen acute or subobtuse; lateral nerves 
8 to 10 on each side of the midrib, distinct; petioles 1 to 3 cm 
long; stipules broadly ovate, obtuse to acute, 5 to 8 mm long. 
Inflorescences terminal, corymbose, conspicuously cinereous- 
pubescent with short appressed hairs, in fruit becoming nearly 
glabrous, about 6 cm long and about as wide as long, shortly 
peduncled or branched from the base. Flowers numerous, white, 
5-merous, their pedicels up to 3 mm long, the bracteoles less 
than 1 mm long. Calyx pubescent, ovoid or slightly urceolate, 
8 mm long, truncate or subtruncate, the teeth, if at all evident, 
very short and obtuse. Corolla-tube about 7 mm long, glabrous, 
the throat densely villous, the lobes oblong, obtuse, 6 mm long, 
2.5 mm wide. Anthers 6 mm long. Style and stigma 15 mm 
“long, the style pubescent in the middle, the stigma cylindric,
