on the narrower side, rounded or very shortly auriculate on the wider, 
the margins entire for a little more or less than half the length of the 
leaf, thereafter with from 4 to 7 acute and often apiculate teeth on the 
wider side and 3 to 5 on the narrower, the apical tooth acute or subacute, 
hardly projecting beyond the general outline; triplinerved, with 2 to 4 
additional veins on the wider side and 1 or 2 on the narrower, these and 
the nerves subparallel nearly free from one another; pilose on both sur- 
faces without conspicuous cystoliths; stipules narrowly oblong, 3 mm 
long, apiculate. ; 
Luzon, Province of Laguna, base of Mount Banajao at 800 m elevation, on 
rocks, Bur, Sci. 9767 Robinson. Nearest to EH. brongniartianum, but besides the 
color of the leaves, having much freer venation, with the base entire for a greater 
distance.

Sublignosum, ramosum, dioicum: receptaculis sessilibus, staminif- 
erorum bracteis haud corniculatis, floribus. tetrameris: foliis sessilibus, 
firmiter membranaceis, plus minusve oblique ellipticis, anguste oblongis, 
vel lanceolatis, margine basi excepta dentatis, haud acuminatis, tripli- 
nerviis ; stipulis lanceolatis, 1 ad 1.5 mm longis. . 
More often dioecious: staminate receptacles sessile; outer bracts free 
except at base, about 2.5 mm long, 3.5 to 4 mm wide at base, the apex 
_ broadly rounded, the keels not reaching the apex, sparingly pilose and 
densely ciliate; inner bracts broadly oblanceolate, 3 mm long, ciliate at 
the apex, not corniculate; bracteoles similar but narrower; perianth- 
segments 4, broadly oblong to lanceolate, 1.5 mm long, shortly corniculate, 
ciliate at least at the apex; anthers about 1 mm long; pistillate recep- 
tacles sessile; outer bracts suborbicular, free for about half their length, 
broadly rounded, not corniculate, about 1.5 mm long, other bracts obovate, 
equally long, densely ciliate; bracteoles similar but narrower; perianth 
minute, 3-lobed, glabrous or more or less ciliate; ovary very shortly 
stipitate, ellipsoid, 0.7 mm long, striate; stigma with deciduous white 
pubescence as long as itself; achenes 1 mm long. 
Erect, much branched, 20 to 60 em high, the lower part of the stem 
glabrous and woody, the upper densely short-pubescent: leaves sessile, 
the lamina firmly membranaceous, more or less oblique, elliptic, narrowly 
oblong, or lanceolate, 8 to 30 mm long, 2 to 12 mm wide, the narrower 
side of the base acute or subobtuse, the wider subauriculate, the margins 
except at the base with conspicuous but rather shallow teeth, or much 
more rarely merely sinuate, the teeth acute or somewhat blunt, directed 
forward, most often 8 on each side but varying from 6 to 12, or with 
fewer on reduced leaves, the terminal tooth 1 to 2 mm long, apiculate, 
but not extending beyond the general outline of the leaf; the upper 
surface glabrous or slightly pilose, with numerous cystoliths, the under
