VIII, c, 4 Merrill: Philippine Melastomataceae, 1 229 
species, and that still more will be discovered in the islands to 
the south of the Philippines. In an additional paper of this 
series it is hoped that later the entire genus, as to its Philippine 
representatives, can be considered, with detailed information 
as to the occurrence and range of the various species and with 
a key to all forms. 
In the following paper the species have been roughly arranged 
according to the distinctive characters selected by Cogniaux for 
grouping the forms. All belong in the section Eumedinilla.

1. MEDINILLA DUODECANDRA sp. nov. 
Frutex scandens glaber, ramis ramulisque teretibus; foliis 
verticillatis, ovato-ellipticis, usque ad 13 cm longis, petiolatis, bre- 
vissime apiculato-acuminatis, basi acutis vel acuminatis, 7-pliner- 
viis, in siccitate submembranaceis vel chartaceis ; cymis axillari- 
bus, solitariis vel fasciculatis, brevibus, paucifloris; floribus 6- 
meris ; staminibus 12, valde inaequalibus. 
A scandent shrub reaching a height of 9 m, glabrous through- 
out. Branches and branchlets terete, light-gray or somewhat 
brownish. Leaves verticillate, 3 or 4 at each node, ovate-ellip- 
tic, 7 to 13 cm long, 4.5 to 6.5 cm wide, when dry somewhat 
shining, the upper surface darker in color than the lower, sub- 
membranaceous or chartaceous, apex very abruptly apiculate- 
acuminate, base acute or somewhat decurrent-acuminate, 7-pli- 
nerved, the two inner pairs of nerves more prominent than the 
outer pair and reaching to the apex of the leaf ; petioles 1.5 to 
2.5 cm long. Cymes axillary, solitary or several at each node, 
few-flowered, less than 4 cm in length, the bracts and bracteoles 
none or very early deciduous; pedicels up to 1 cm in length, 
slender. Calyx cup-shaped or broadly urceolate, truncate, about 
4 mm long. Petals 6, pink, obliquely oblong-obovate, about 1.5 
cm long, 9 mm wide. Stamens 12, in two rows, very unequal, 
the longer 6 about 23 mm in length, the shorter six 15 mm long ; 
anthers of the longer stamens slender, the appendage produced 
about 2.5 mm below the cells, there with a slender dorsal spur 
about 2 mm long, slightly thickened at its apex, and with two 
anterior obtuse appendages less than 1 mm long ; anthers of the 
short stamens stouter than those of the long ones, the connective 
not produced at the base, the dorsal spur slender, thickened at
