leaves linvo ^^^reat similarity to lliose of K. cannui, except that in E. htinahinii.se 
tlip baso of tlip narrower side of the hiiuiiia ends some distance from the petiole, 
while on the other side it is usually at least subaiirieulate. But there are 
intemiediates to such an extent that if there were no other character, the 
spooies eould not be hebl separate. That character seems to bt* supplied by the 
stipules, which are lon<?er aud usually wider in E. hnnahucnfie, their length 
reaching 2o mm on Mcnill HoIO, and ranging- from 14 to 22 mm on tbe College 
of Afrriculture collection, wliile thev are from 10 nun (young) to 16 mm on 
the type. The Zai(d)oanga collections cited in the description of >>'. hanahaense 
also show this character, as do two numbers from Mount Pulog, Benguet, 
Fr»'. Bur. UlU-Ti, IGO-'jl Cnrran, Alcrritt, it Zavkolclce, originally identified as 
E. caHnoi and responsible for part of the variation recorded for that species 
with regard to this very character, although by some oversight they were not 
cited. All of these should be referred to E. hanahaense. The stipules of E. 
carivoi and E. rariabilc are usually narrower, and vary in leugtli from 3.5 
to 11 mm, slightly longer on the E. rarmhile type than on the other, but are 
usually from 4.5 to 7 mm, in contrast to a normal 15 to over 20 mm on E. 
h(maharnse. Taken in conjunction with the other characters, insuflficicnt as 
the latter alone would be, E. hauahaentic and E. carivoi are better held distinct. 
This amended view of the afTuiities of /;. haiuihaeusc also brings it very close 
to E, edulc. which has wider leaves, leas acuminate, a still more pronounced 
basal auricle, and stronger venation. It will not be surprising if future collec- 
tions render E. ediile untenable as a separate species. As it is, the Mount 
Mayon phint cited under E, edule. is rather E. hanahaense. 
Vanoveiherfjli 82H, the type of E. rariahife, was pistillate, an<l on its general 
appearance, no close alliance with E. car'moi would he suspected, hut T now 
find it very ditlicult to keep them apart, although their union would throw 
discredit on the validity as differentiating characters of leaf-outline, peduncleil 
as opposed to sessile staminate receptacles, pinnate as contrasted with the most 
delinite triplinerved venation, and coarse teeth or even lobes as against entire 
margins, all in the one case. No rme could fail to distinguish the two types 
of leaves; one of the difficulties is that some plants having the upper leaves 
of the narrow, pinnate-veined tvpe of E. variahile, have others lower down on 
the same stems which approach closely to the normal type of E. cannoi. m ^ 
is to some extent shown on plate 1 of this vohime, hut is more definite on 
collections recently obtained. In no case has a plant yet been obtained with leaves 
which are entirely typical of both sj>ecies. Vatwverherqh 1220 is certainly fi. 
rarhihile; the receptacles aie borae on slender peduncles usually 10 to IS tuni- 
long, but shorter in the ca.se of very young receptacles; the bracts are baie > 
corniculate as in E. cariymi, the flowers tetramerous. The staminate receptacles 
on the type sheet of /;. carinoi have usually rather stout peduncles 4 to 6 
mm long, hidden on a front view by the receptacles themselves, or the youn^ 
receptacles may he sessile. For. Eur. .)^//J Vnrran, Merrill .)N}', 76'.?S, /?'"■ ' '^*-

nun.
