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 nearty 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. 97,67 Robinson. Nearest - to E. brongniartianum, but besides tlie 
color of the leaves, having much freer venation, with the base entire- for a greater 
distance.

Sublignosum, ramosum, dioicum: receptaeulis sessilibus, t staminif- 
erorum bracteis haud corniculatis, floribus tetrameris: foliis sessilibus, 
firmiter membranaceis, plus minusve oblique elliptieis, anguste oblongis, 
vel laneeolatis, margine basi exeepta dentatis, haud acuminatis, tripli- 
nerviis; stipulis laneeolatis, 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 cm 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
