veins 6 to 8 on the wider side; fewer on the narrower, but with others 
subparallel 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, 3495 Mearns. At first sight appearing 
to be a succulent, unbranched, large-leaved form of EB. 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 H. tomentosum Wedd., afterwards made by him a variety of JZ. 
sessile, a species that can not be identified at present: both seem to come near 
to it, but not sufliciently; however, it is to EH. benguetense that it seems to 
approach most nearly of all pur 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- 
oblanceolate, 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 em 
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 FB. obtusiusculum, the 
apex protracted into a definite subcaudate serrate acumen 1 to 2 em long; 
triplinerved, with 6 to 8 additional veins and others nearly as prominent, 
forming a continuous lateral vein; cystoliths crowded on the glabrous 
upper surface, inconspicuous on 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 #. obtusius- 
culum, there are probably others to be found in the staminate receptacles, but 
those of FE. contiguum are too young to permit positive statement.
