but from ifiquers description the leaves of tlie fornier are more pubesocnt than 
those of the type of the species.^ The h'aves of K. Inyunensc also vary in 
pubescence, but in tiiat species the exphmatiou in at least some ca.ses is humidity 
and not age. The stipulcR of E. vntcrophyllum are 3 mm long, those of K. 
imJudofiUm only 1 mm long. The stamina te receptables of E. ht(jnitrnsr are 
usually much larger than those of E. pahidosuui are said to be by '^[il)uel, 
but they must vary in this respect with age. and this diirerence would have 
to be verified by very full collection-; before it could he used as a positively

this is' a very real alliance for E. halronrnsr C. B. lloh.. hut the latter is a 
coarser plant with stems au.l branches of a yellowish or grayish color, while 
those of E. ihaiiclrouh's are rather dark-reddir.h. Except for the ultimate 
branchlets which are very densely pubescent in both species, E. halconeusc is 
distinctly the more pubescent. The leaves are of different outline, longer and 
narrower in /;. halcoaensc, with the apical tooth nuich farther prolonged. E.

It has much the ajipearaiicc of being a reduced state of E luzouense C. B. Rob 
but with this difference, that when the leaves of that species become reduced 
ihey take on a different form either from those of better developed plants of 
the same species or of those of the Bornean collection. There are no opposing 
leaves of smaller si/^ than the other., tlic characteristic of /;. surcuhsmn Wight,
