anthers are therefore strictly extrorse ; the connective is almost 
terete, somewhat compressed, erect in position, and about one- 
sixth of the length of the filament; the two anther-cells are 
distinctly separate, thin, membranaceous, white, flattened, boat- 
shaped and valveless, fixed one on each side of the connective ; 
they are longer both above and below, so that the anthers are 
emai’ginated at the apex and base ; they generally open extrorsely 
by the separation of the posterior margin of the cells from the 
connective, or they sometimes, though rarely, separate by both 
margins. The ovarium has been described as being glabrous, 
but I have constantly found it clothed with long, erect, setaceous, 
shining, white hairs ; the lower part is invested by a glabrous, 
adnate, cup-shaped disk : the style is erect and somewhat bent, 
glabrous, rather subulate, slender, and of the length of the sta- 
mens : there is no apparent stigma, but the apex of the style is 
hollow and crowned with three very minute teeth : the ovarium 
contains three radiate, excentric cells, each showing two ovules 
suspended from near the apex.

This species comes very near E. acuminatum ; the leaves are 
very shining above as in that species, and ferruginous beneath, 
but the hairs that clothe its under surface are so minute as to be 
seen only under a strong lens ; they are somewhat convex above 
and the margins are very i-evolute, the attenuated apex being 
deeply channelled and curved downwards; they are about 4^^ 
inches long and 2 inches wide, with a somewhat slender and 
almost terete petiole, which is often suddenly deflexed. The in- 
florescence is axillary in a few of the upper leaves, but is mostly 
terminal in branching alternate racemes, each about three- 
quarters of an inch long.

berrimis, pallide glaucis, sub-nitentibus, subconvexis, nervis
