long, 0.75 mm. wide, basifixed, cordate at base, emarginate at

green, turning roseus to incarnatus when mature, orange red 
when dry, 3-celled and 3-ovuled but usually only 1 devel-

Type specimens 12967 in flower and 12726 in fruit, A. D. 
E. Elmer, Puerto Princesa (Mt. Pulgar), Palawan, March and

A characteristic tree in the secondary forests of the vast 
level tract of land built up mainly by gravelly residue from 
the near mountain range. 
It does not agree with the description nor with Malayan 
specimens of G. glomerulatum Hassk. although very closely 
related to it. | ‘ 
Gelonium pulgarense Elm. n. sp. 
An erect and quite a rigid shrub; branchlets ascending, 
numerous, gnarly appearing, glabrous, covered with smoothish 
yellowish gray bark, the green tips glabrous and when dry red- 
dish brown. Leaves alternate, chiefly toward the ends of the 
twigs, suberect, flat, glabrous, unequal in size, the entire mar- 
gins revolute in the dry state at least, the larger blades 4 em. 
long by 2.5 em. wide across the middle or a trifle above it, the

ed, papillately punetate on both sides, elliptie or the smaller 
ones rotund; midvein prominent beneath, glabrous; the 3 to 5 
lateral ones faint, their tips becoming invisible, retieulations 
none; petiole only a few mm. long, glabrous; reddish brown. 
Flowers in small clusters, in the leaf axils mostly, glabrous; buds 
globose, also glabrous; the glabrous and subcoriaceous pedicels
