NoveMBER 29, 1911] New MELASTOMATACEAE 1229 
Mts.), Province of Negros Oriental, Negros, April, 1908; also 
my number 11254 from the vicinity of mount Apo. 
This small tree trunk climber was discovered on a moist 
wooded ridge at 4250 feet altitude. The Apo plant was collected 
[ F in similar ecological conditions and was called by the Bagobos 
» "Cayaupang." Named after Dr. C. B. Robinson who has de- 
scribed a number of new Philippine Melastomataceae. 
M. malindangensis Merr. but fruits larger, pedicels shorter 
and involueral braets much larger. The mount Apo specimens 
are very near our new species, yet they seem to approach M. 
pachygona C. B. Rob. We have in our archipelago quite a group 
of these very closely allied species which belong to the first 
section of Medinilla based upon M. rosea Gaud. from Guam. 
Medinilla burebidensis Elm. n. sp. 
Shrubby and scandent; stem terete, 2.5 cm. thick, flexible, 
numerously branched at the top; wood whitish, soft, without 
odor and taste; bark thick, grayish, smooth and lenticelled, minu- 
tely checked on the stem; young twigs green, striate, pulverulent, 
finely glabrous. Leaves scattered in whorls, coriaceous, ascend- 
ing, the short obtuse apex recurved, dull green above and very 
much lighter so beneath, when dry griseus beneath and nearly 
blaek on the upper side, entire, glabrous, persistent, copious, 
elliptieally oblong, the blades 4 em. long by one half as wide aeross 
the middle, frequently smaller and broadly oblanceolate, base 
cuneate to obtuse and occasionally slightly inequilateral, trip- 
linerved, submarginal line present in the larger leaves, without 
cross bars, petioles glabrate and 5 mm. long. Infrutescence 
ascending from the leaf axils; peduncles slender, strict, less than 
1 em. in length, finally glabrous, few umbellately branched 
at the distal end; secondary peduncle 7.5 mm. long, strict, very 
slender; pedicels thicker, purplish, terete, 4 mm. long, subtended 
by 2 subpersistent linear bracteoles; fruits short ovoid, very 
deep purple, 7.5 mm. across, apex deeply cup shaped. 
Type specimen 11839, 4. D. E. Elmer, Todaya (Mt. Apo), 
District of Davao, Mindanao, September, 1909. 
A small tree climber and forming tangled masses on a dry 
wooded ridge at 4500 feet of mount Burebid. This has leaves 
twice as large and of a different shape than those of the follow-
