add many other species from tropical Asia, and Madagascar, so 
that the range of the genus is considerable. In its floral struc- 
ture it is very near Icacina : it differs from Apodytes, Rhaphiostylis 
and Leretia, in the absence of any glandular appendage or raised 
teeth on the summit of the ovarium, and from both, as well as 
from Icacina, in having a shorter, erect, and stronger style, and 
a lobed hollow stigma, in its calyx being more entire, the anthers 
more ovate and not so deeply cleft at base, and in its entirely 
free hypogynous disc, smooth outside and generally very pilose 
within : in the cristulate apex of the nut, it bears some analogy 
with that of Pennantia. It differs from Apodytes and Pennan- 
tia, but agrees with Stemonurus in its larger embryo, with large, 
oval, foliaceous cotyledons, that nearly equal the length of the 
albumen. It is the Stemonurus of Dr. Wight, but differs essen- 
tially from the Stemonurus of Blume. 
The Nothapodytes of Blume agrees with this genus in every 
essential feature. I cannot perceive any difference in the struc- 
ture of the flowers between the Jamaica and Asiatic species, except 
in the more glabrous habit of the former, their more lanceolate 
leaves, and the perfect smoothness of the hypogynous disc, 
features that cannot constitute any generic distinction. I have 
therefore divided them into corresponding tribes. 
The following outhne of its generic characters has been derived 
from my own observations.
