8trigo?:c; almost or quite trinorved, tlie nerves extending to tlie l)rtse of 
the lamina, auricle exclnded, bnt on the wider side of the wider leaves 
little longer than the succeeding, other veins usually 3 on each side, some- 
times 2 or 4, minor venation hardly conspicuous; stipules narrowly 
lanceolate to ovate, 1 to 1.8 nun hing, with crowded cystolitlis and 
sometimes ciliate. 
Luzon, Suhprovinoe of Beiiguet, BiigTiio, in ravinos at about 1,400 m eleA'ation, 
Bur. Sci. Wrio Runios. Superficially, the species lias more tlie appeiirance of 
E. podophfjlhnn Wedd. than of any other hitherto found in the Philippines, 
but differs ^videly from it in the slender stem, wider, larger and more deeply 
cut leaves, stronger and somewhat different venation, and the absence of the 
typical leaf-base. It is really in the alliance of the species from E. acrophilum 
to E. hafitatum, and on a summary of characters probably closest to E. phiUp- 
pincnae Elmer, from which it dilTers by its uiore densely pubescent stem, and 
the shape, color, comparatively deeper and much coarser dentation, and venation 
of the leaves. It has also much resemblance to E. hookerianvm Wedd., but 
that has the stems, staminate bracts, and bracteoles ghibrous, these bracts are 
more corniculate, the leaves are usually more acuminate, with different, venation, 
and longer stipules. Probably the closest alliance of all is with E. ohlufuifolnu'i 
Reinecke, of Samoa, the name indicating- one difference. The Philippine .plants 
are larger with larger leaves, the Samoan have peduncled staminat;- receptacl's.

Additional collections, Merrill 7627, from mossy forest on Mount Tonglon, 
Ben^iiet, and Phil. PI. 80^ Merrill, from mossv forest at Pauai, Benguet, both 
growing at about 2,200 m elevation, and reexamination of the type material, 
show that in the smaller-sized receptacles only one of each of the two mner 
pairs of staminate bracts may be developed. The larger-sized receptacles are 
of the type common to the genus. The species is, in all probability, a very 
primitive form. Pistillate flowers have not yet been collected.
