the lower surface much paler than the upper, glabrous except 
for the sparingly appressed-strigose nerves and reticulations, 
the apex rather sharply acuminate, the base obtuse or rounded, 
5 -nerved; petioles densely strigose, 5 mm long or less. Flowers 
white or very pale-pink, in few-flowered, terminal, ebracteate 
cymes, the cymes 2 to 3 cm long, the flowers rarely or never ex- 
ceeding 9 in each. Calyx ovoid, including the lobes about 1 cm 
lo-ng, outside very densely strigose with simple, closely ap- 
pressed, narrowly ovate, acuminate, usually purplish scales, the 
tube ovoid, about 6 mm long and 5.5 mm in diameter, the lobes 
5 or 6, lanceolate, about 4 mm long, densely strigose, alter- 
nating with very small, 1.5 mm long scales scarcely larger than 
those on the tube. Petals 5 or 6, obovate, nearly equilateral, 
about 1.3 cm long, 9 mm wide, apex broadly rounded-truncate, 
margins more or less ciliate. Stamens 10 or 12, slightly un- 
equal, the longer filaments 7 mm long, the shorter 6 mm, the 
anthers oblong, obtuse, straight, the longer ones 3 mm long, 
connectives produced 1 mm, the shorter ones 2.5 mm long, the 
connectives produced 0.5 mm, the anterior appendages in both 
curved, 0.5 mm long. Ovary 5- or 6-celled, the apex subconical, 
densely hirsute. 
Luzon, Ifugao Subprovince, Mount Polis, Bur. Sci. 19835 McGregor, 
February, 1913. 
A very characteristic species, belonging in the third group, as outlined 
by Cogniaux, with Melastoma denticulatum Bl., M. mariannum Naud., M. 
sylvaticum Bl., and M. francavillanum Cogn. Striking characters are its 
small leaves, somewhat glaucous beneath and glabrous on the lower surface 
except for the nerves and reticulations, its small, nearly white flowers, and 
its short anthers which are slightly unequal in length, the connectives pro- 
duced but 0.5 to 1 mm.

Frutex circiter 1 m altus omnibus partibus longe penicillato- 
setosis; foliis chartaceis, oblongis, acuminatis, usque ad 9 cm 
longis, basi acutis, 5-nerviis ; paniculis terminalibus, paucifloris ; 
floribus 5-meris, circiter 1 cm diametro.

slender, setose hairs 3 to 4 mm in length, those on the leaves 
usually pale, those on the branchlets and inflorescence purplish. 
Branches gray, terete, slender, setose-penicillate. Leaves oblong, 
chartaceous, green and of about the same color on both sur- 
faces when dry, 5 to 9 cm long, 1.5 to 3 cm wide, apex acumi- 
nate, base acute, rarely somewhat rounded, 5-nerved, the outer
