266 |Mr.J. Miers on the Menispermacce. 
Dr. Burchell’s herbarium, where on each axil one or two very 
short pedicels bear separately a single minute flower, with two 
oval concave sepals, placed oppositely, with their margins some- 
what imbricated in estivation ; at the base within, and opposite 
to each sepal, isa very minute scale-like fleshy petal, placed at 
the base of a central ovary, which is nearly the length of the sepals, 
without any style, and with an obsolete stigma. This structure 
will be seen to offer much analogy to that of “the genus Peraphora, 
and places them in a position intermediate between Cissampelos 
and Homocnemia, differing from the former in having double the 
number of floral parts, and from the latter in having half as many. 
Messrs. Bentham and Hooker were evidently unacquainted with 
the facts here shown when, in their ‘Genera Plantarum’ (p. 38), 
they amalgamated this genus with Czssampelos. The structure 
of the female flower, with a different kind of inflorescence, and 
the peculiar habit of all its species, certainly claim for Antizoma 
the rank of a distinct genus.
