287 LEAFLETS OF PHILIPPINE BOTANY (Vor: I. Arr. 16 
beneath, nearly parallel, slightly ascending, strict, terminat- 
ing in the apex of the teeth, with dirty yellowish brown 
hispidulous hairs, reticulations obsolete; stipule caducous, 
3 mm. in length, hyaline sides, the 2 nerves extended into 
bristle like points. Inflorescence a very dense flattened cluster, 
frequently 5 mm. across, in the leaf axils and usually extend- 
ed over the upper surface of the stem; subtending bracts 
spreading, as large as the cluster, the basalone half united, 
foliaceous, its segments linear and numerous; pistillate flow- 
ers subsessile, surrounded by several linear sparingly ciliate 
` involucral bracts about 1.5 mm. long and which are more 
or less united at the base or around the short pedicel; 
perianth absent but the base of the ovary thickened; ovary 
fusiform, brown, short stipitate at the base, glabrous and 
more or less dotted, apex with a hyaline point. 
Type specimen 9193, A. D. E. Elmer, Lucban, Province 
of Tayabas, Luzon, May, 1907. A very pretty  Elatostema, 
commonly found on moss covered rocks scattered in stream 
beds of wooded ravines at 750 meters on Mount Banahao. 
It is ata glance distinguished from E. obovatum Wedd. by 
its different venation. 
Elatostema laciniatum n. sp.—A very succulent loosely 
tufted herb; stems soft, green, suberect or reclining, sparingly 
branched, the longer ones 1 m. long, but frequently much 
smaller. Leaves usually opposed by very small lamina, ex- 
tremely diverse in size and shape, glabrous, succulent and 
soft, glossy and deep green on the upper surface, conspic- 
uously whitish green beneath, nearly black when dry, mostly 
with inequilateral sides, apex slenderly acuminate or sub- 
caudate, base obliquely subcuneate; the smaller ones bract 
like, linear lanceolate and entire; the larger blades 16 cm. 
long, about 5. cm. wide, entire below the middle, coarsely 
dentate above^the middle, oblong to broadly oblanceolate; 
petiole less than 1 em. long, glabrous; nerves quite evident 
beneath; the main nerves 5 to 7 or even 9 on each side 
of the large midvein, curved and very oblique, reticulations 
coarse and very obscure in the smaller leaves. Glomerate 
inflorescence 1 to 2 em. across, in the axils of the leaves 
along the middle of the larger stems, few and very loosely
