30. CLAMBUS. 
This genus was founded by me, more than twelve years ago, 
upon a Mexican plant, collected by Ruiz and Pavon, its general 
characters being sketched, two years since, in my synopsis (huj. 
op. xii. p. 123). It belongs to the Cissampelidee, and differs 
from Cissampelos in its very different habit, its inflorescence, 
and the presence of six sepals and six scale-like petals in the 
male flower: in this latter respect it approaches Pericampylus 
and Pselium; but its anthers are combined in a peltate disk 
supported on a slender filament, as in Cissampelos. It offers 
some analogy towards Stephania; it has the same number of 
sepals, but double the number of petals, a different kind of 
inflorescence, and a dissimilar habit. The female plant is un- 
known. ‘The genus differs from all others of the Cissampelidee 
in its leaves not being peltate, and therefore not palmatinerved, 
the nerves being all imparipinnate as we find them in Pycnar- 
rhena, Penianthus, and some species of Hypserpa: the leaves are 
supported upon very short petioles, and are ovate or elliptic, 
with about eight pairs of alternately diverging nerves; they are 
very reticulated above, glabrous on both sides, but opakely white 
beneath: this cretaceous appearance, when viewed under a lens, 
is found to consist of a prominent network of white and ex- 
tremely minute crossing fibres, like a spider’s web, which fills 
the areoles of the ordinary venous reticulations. The inflores- 
cence is axillary, upon an elongated, very slender rachis longer
