Pericampylus incanus] but its leaves are not crenated on the 
margins, its inflorescence is much shorter and not so dilated or 
so frequently umbellate. The leaves are 1:^-2 inches long, 1|- 
inches broad, on a petiole f-lj inch long. The inflorescence 
scarcely exceeds 5 or 7 lines in length, on a peduncle shortly 
branched, the branches terminated by several minute pedicel- 
lated flowers, aggregated in a short corymbose head. 
23. Ileocarpus. 
This genus was proposed by me in 1851 for a plant in Schim- 
per’s Abyssinian collection : it is allied to Pericampylus and 
Menispermum on account of its putamen and seed, and approaches 
the following genus, Homocnemia. It differs, however, from 
Menispermum in its isomerous stamens, and from Pericampylus 
in its peltate leaves, in having only three membranaceous sepals, 
three smaller alternate petals, and a single ovary, with a short 
thick style and a somewhat erect stigma. Homocnemia differs 
from it in its tetramerous arrangement, having four sepals, four 
minute petals, and one compressed ovary on a disk-shaped sup- 
port, and an obsoletely 2-lobed stigma. The authors of the 
‘ Flora Indica ’ and of the new ‘ Genera Plantarum ’ unite this 
genus with Stephania, and consider that the typical plant 
is not distinguishable from Stephania hernandifolia. But Ileo- 
carpus cannot well be reconciled with Stephania, on account 
of the absence of the perforation in the condyle, the presence 
of which is a universal feature in every species of that genus 
that I have seen. It cannot be denied that the plant in 
question has peltate leaves, and a habit like that of Stephania ; 
but not more so than are found in Cyclea, Clypea, and many 
species of Cissampelos : the latter and Clypea are indeed the only 
genera among the whole group that harmonize with Ileocarpus 
in the structure of the putamen ■, the latter genus differs from all 
the rest in the shortness of its cotyledons compared with the 
length of the radicle.
