veins 6 to 8 on the wider side, fewer on the narrower, bnt with others 
snbparallel to them nearly as prominent; upper surface sparingly pilose 
with numerous cystoliths, under densely pilose; stipules lanceolate, acute, 
about 3 mm long. 
Luzon, Province of Benguet, Bur. Sci. 8495 M earns. At first sight appearing 
to be a succulent, unbranched, large-leaved form of E. benguetense, but sufficiently 
distinct to ensure its ready recognition, and also possessing many additional 
points of separation. Both of these have been carefully compared with the 
descriptions of E. tomentosum Wedd., afterwards made by him a variety of E. 
sessile, a species that can not be identified at present: both seem to come near 
to it, but not sufficiently ; however, it is . to E. benguetense that it seems to 
approach most nearly of all our species.

Staminate receptacles (only one seen, that young) sessile; outer bracts 
free from one another except at the. base, depressed-orbicular, 3 mm 
long, 4 mm wide, broadly rounded and not corniculate at the apex; some- 
what pilose and ciliate; inner bracts oval, 2 mm long, not corniculate, 
densely ciliate; bracteoles oblong-oblanceolate, 2 mm long, densely pilose 
and ciliate; perianth-segments 5, lanceolate, pilose, at the apex, hardly 
corniculate: pistillate receptacles sessile; outer bracts- triangular-ovate, 
free for about 2 mm, very shortly corniculate, ciliate, somewhat pilose; 
other bracts . oblong-lanceolate, densely pilose-ciliate ; bracteoles linear- 
oblanceblate, excluding the pilose apex about 0.8 mm long; perianth 
somewhat unequally 3-lobed, usually over 0.1 mm long; achenes ovoid, 
0.6 mm long, pale with about 8 brown longitudinal lines. 
Erect, somewhat succulent, more or less tufted, not, or sparingly 
branched, the stems with short' dense appressed substrigose pubescence : 
leaves very shortly petioled or the upper subsessile, the- lamina firmly 
membranaceous, obliquely elliptic or elliptic-oblanceolate, 5 to 9 cm 
long, 14 to 24 mm wide, or some of the basal reduced, the base acute or 
subacute on both sides or rarely rounded on the wider, marginal teeth 
about 20, usually more acute and spreading than in E. obtusiusculum , the 
apex protracted into a definite subcaudate serrate acumen 1 to 2 cm long ; 
triplinerved, with 6 to 8 additional veins and others nearly as prominent, 
forming a continuous lateral vein ; cystoliths crowded r on the glabrous 
upper surface, inconspicuous an the pilose under surface; stipules lan- 
ceolate, acuminate, ciliate, 3 to 4 mm long.

In addition to the characters noted as distinctive between this and E. obtusius- 
culum, there are probably others to, be found in the staminate receptacles, but 
those of E. contiguum are too young to permit positive statement.
