FLACOURTIACEAE. 
Homalium sorsogonense n. sp.—A small tree, 8 m. high, 
with a 2.5 dm. bole; branches lax, light gray, covered with 
small lenticels. Leaves diverse, chartaceous, elliptic or sub- 
rotund, crenately toothed or serrate, glabrous, the average 
blade 6 cm. long by 4 em. wide, apex broadly rounded and 
terminated by a short blunt point, base equally rounded or 
sometimes obtuse; lateral nerves more numerous from near 
the base, ascendingly curved, more prominent beneath, retic- 
ulations also prominent; petiole subglabrous, 3 to 5 mm. in 
length, easily detached at the base. Spicate racemes terminal 
or subterminal, slender, ascending, at least 1 dm. long, in 
the younger state short tomentose, flower bearing from near 
the base; flowers creamy white, 1 to 3-clustered, subtended 
by small pubescent braets; pedicels pubescent, 2 mm. long, 
persistent, artienlate at the apex; calyx similarly pubescent, 
turbinate, more or less carinate, distinctly stipitate at the 
base; its 5 segments 2 mm. long at least, spatulate or obo- 
vately pandurate, soft, ciliate; corolla a second series of 5 
perianth segments similar but usually a trifle shorter and 
conspieuously narrower; stamens about 10; filaments 2 mm. 
long, subequal, slender, glabrous or sparsely hairy at the 
thickened base, indefinite; anthers 0.25 mm. long, ellipsoid, 
inserted upon the hairy disk of the ovary, not exceeding 
the perianth segments; pistils about 5, hairy, the upper one 
half divided into 2 setae like arms; ovary 5-valved at the
