crowded near the ends of the branches, the flower-bearing por- 
tions 2.5 to 5 cm long, 4 to 8 cm wide, the axis, branches, and 
branchlets slightly pubescent, the bracteoles none or very early 
deciduous. Calyx somewhat urceolate, 2 mm long, the teeth 
4, very short. Corolla, in bud, 5 mm long. Fruit subglobose, 
glabrous, 5 to 8 mm in diameter. 
Mindanao, District of Cotabato, Gian, For. Bur. 18250 Miranda, June, 
1912. 
A species well characterized by its very broad leaves and its terminal 
trifid inflorescence, the small flowers crowded near the ends of the primary 
branches. Its alliance seems to be with Ixora grandifolia Z. & M.

Frutex vel arbor parva, glabra ; foliis oblongis, coriaceis, usque 
ad 25 cm longis, breviter petiolatis, obtusis vel obscure late 
acuminatis, basi subtruncato-rotundatis, nervis utrinque circiter 
15, subtus prominentibus ; stipulis abrupte longe setaceo-apicu-

longis, ramis paucis, patulis, paucifloris; fructibus 6 ad 9 mm 
diametro. 
A shrub or small tree, glabrous, the branches terete or some- 
what compressed, pale-brownish, smooth, the ultimate ones about 
5 mm in diameter. Leaves oblong, coriaceous, 20 to 25 cm long,
