This species is remarkable for the shape of its leaves, which 
are almost orbicular at the base and summit, are 2| to 3;^ inches 
long, 2^ inches broad, on a deeply grooved petiole 6 or 7 lines 
in length ; they ai’e thick and coriaceous, very polished above, 
with a finely shagreened surface, and densely covered beneath 
with short yellowish tomentum ; the simple racemes with a few 
immature drupes are about f inch long. 
2. Emmotum acuminatum. Pogopetalum acuminatum, Benth. 
loc. supr. cit. 685 ; — arbor 5-orgyalis, foliis ovatis oblongisve, 
apice longissime et anguste attenuatis, mucronulatis, coriaceis, 
fusco-rufulis, supra lucidis et glaberrimis, in costam sulcatis, 
nervis paucioribus vix prominulis, venis transversis immersis, 
subtus pallide ferrugineis, glandulis minutis creberrime punc- 
tatis, pube rara instructis, petioloque sulcato leviter pubescen- 
tibus, demum glabris; raeemis geminis, floribus aggregatis 
griseo-pilosis, petalis ovali-oblongis, intus in earinam pilis 
longis rufis lanatis, marginibus utrinque glabris ; ovario pilis 
destitutis et e glandulis minutissimis asperis glaueo-pruinoso, 
disco glabro insito ; stylo excentrico elongato, stigmate obso- 
lete 3-dentato. — llio Negro, Brasilise (Schomb. 970). 
The branchlets are somewhat compressed and angularly 
striated : it is however distinguished from the other species by 
the long attenuated summit of the leaves, which are also of a 
remarkably dark copper or reddish colour when dried; they are 
about 4 or 4| inches long, including the suddenly narrow apex 
of half an inch in length ; they are If to 2i inches broad, on a 
petiole 5 lines long ; the nervures, about seven pairs, are parallel, 
very divergent, curving, with finely reticulated transverse veins ;
