much more emphatically pinnate than in that species, the lowest veins being 
very much shorter than the upper; the outer bracts of the staminate receptacles 
are united except toward the margins, and the pistillate receptacles, recently col- 
lected on Mount Apo, are peduneled.

E. platyphyllo Wedd. affine: receptacnlis sessilibns vel subsessilibus, 
magnis; bracteis basi coalitis discum efformantibus, baud vel brevissime 
corniculatis ; floribus staminiferis tetrameris : foliis breviter petiolatis, 
membranaceis, oblique elliptico-obovatis vel oblongis, basis uno latere 
acutis altero grosse auriculatis, apice acuminatis, triplinerviis ; stipulis 
oblongo-lanceolatis, acutis, circiter 2 cm longis. 
Staminate receptacles solitary, sessile or subsessile, up to 2 cm in 
diameter, glabrous throughout, the bracts united at their bases to form 
a disk about two-thirds the diameter of the receptacles, the free portions 
of the outer pair 4 mm long, 13 mm wide, broadly rounded, keeled but 
hardly corniculate; of the next two pairs about 5 mm long, 10 mm wide, 
keeled and slightly corniculate ; bracteoles oblong-oblanceolate, 4 mm 
long, slightly corniculate; perianth-segments 4, 2.5 mm long, the outer 
broadly lanceolate, apiculate, the inner narrower : pistillate receptacles 
sessile, when flattened nearly oblong, up to 15 by 13 mm, the bracts 
fused but sufficiently free at least at their margins for the three outer 
pairs to be traced, all glabrous, barely corniculate ; bracteoles linear- 
oblaneeolate, 2 mm long, ciliate-serrate ; perianth 3-lobed, about 0.15 mm 
long; achenes broadly ellipsoid, 0.5 mm long, obscurely striate. 
Plants succulent, 50 cm or more in height, the vegetative parts 
glabrous : leaves shortly petioled, oblique, elliptic-obovate or oblong, 16 to 
23 cm long, 3.5 to 9.5 cm .wide, the base of the narrower side acute, that 
of the wider produced into an auricle retaining or slightly increasing the 
width of that portion of the lamina exterior to the nerve, the margin 
of the narrower side entire for a little more or less than half its length, 
then with from 7 to 12 teeth, that of the wider side with the lowest teeth 
nearer the base and 15 to 20 in number, the apex gradually or somewhat 
abruptly contracted into an acumen 1.5 to 2 cm long; triplinerved, ad- 
ditional veins 5 to 7; cystoliths very numerous and conspicuous on the 
upper surface, on the type-sheet especially so and of larger size along the 
principal veins, much less so beneath ; stipules oblong-lanceolate, acute, 
about 2 cm long.
