Elatostema microphyllum n. sp.—A _ subcaespitose herb, 
with slender sparingly branched 3 to 7 em. long stems 
‘which when young are short strigose. Leaves distichous, 
alternate, 2 mm, apart, divaricate or only a trifle ascend- 
ing, very thin, dull green above, subglaucous green beneath, 
drying green, oblong to obovate or obliquely cuneate, margins 
below the base entire, prominently dentate toward the apex, 
8 mm. long, 3 mm. wide immediately above the middle, 
occasionally smaller, apex obtuselv rounded, base cuneate and 
inequilateral, subsessile; the upper lateral side with only 1 | 
basal nerve running nearly parallel with the margin; the 
opposite side with 5 nerves, the basal one subparallel with 
the margin; the second and third oblique and arising from 
the midvein above the middle of the blade; stipule ovate, 
0.5 mm. long, comparatively thick. Inflorescence sessile, very 
dense, elongated, ascending from the leaf axils, not exceed- 
ing 3 mm. in length, greenish; bracts sparsely strigose, 3 to 
5-lobed, spreading, the lobes obtuse to acute and 1.5 mm. 
in length; perianth of flowers equalling the bracts, linear, 
‘apex obliquely truncate, green, conspicuously ciliate, united 
around the base of the short pedicel; ovary glabrous, hyaline, 
0.75 mm. in length, fusiform, apex bearing a comparatively 
large capitate stigma; perianth lacking. 
Type specimen 9149, A. D. E. Elmer, Lucban, Province 
of Tayabas, Luzon, May, 1907. A most dainty species of 
this group of plants, forming handsome tufts upon moss 
covered rock in stream beds of ravines at 700 meters on 
Mount Banahao. Not infrequently the foliage reminds one 
of depauperate forms of E. podophyllum Wedd. 
Elatostema pinnatinervia n. sp.—Tufted, suberect or the 
outer stems subdecumbent, from 5 to 25 cm. high; stems 
rather thick, very sparingly branched, finely tubercled or 
scurfy. Leaves submembranous, drying green, distichous, al- 
ternate, 1 cm. apart, divaricate, obovately oblong, 2.5 em. 
long, 1.5 em. wide just above the middle, but frequently - 
much smaller especially toward the base of the stems, apex 
rounded, base subcuneate and rather abruptly rounded, sub- 
sessile, edges coarsely and deeply dentate, glabrous except 
the nerves beneath, paler green beneath; nerves conspicuous
