4. Cissus trifoliata. Three-leaved -Cissus. 
Leaves 3-foliate glabrous, leaflets ovate acuminate 
at both ends setaceo-serrated submembranaceous, 
branches subalate. 
Bryonia alba triphylla maxima, Sloane , I. 233. t. Hi. f. 2.

HAB. Common. 
FL. July — September. 
Stem woody at the base, climbing : branches herbaceous, 
swollen at the joints, angulose, subalate, glabrous. Leaflets 
petiolulated, ovate, acuminate at the apex which is sharp, sub- 
acuminate at the base, remotely and sparingly setaceo-serrated, 
snbmembranaceous, glabrous (except a few hairs in the axils of 
the nerves beneath), nervose, rugulose, reticulato-venose ; the 
lateral leaflets unequilateral at the base : petiole angulated, 
channelled above. Stipules small, subrotundo -ovate, fleshy and 
swollen at the base. Tendrils opposite to a leaf, bifurcated, 
long, filiform. Peduncles opposite to a leaf (occupying the 
place of an absent tendril), or subterminal, dividing into 3 or 
more horizontally spreading branches, subdivided into two 
branchlets, each bearing an umbellule with a solitary pedicelled 
flower at the bifurcation. Flowers numerous, small, scarlet, 
shortly pedicelled. Bracteas small, marescent, at the divisions 
of the peduncle. Calyx sub-entire. Petals scarlet, oblong, de- 
ciduous. Filaments erect ; anthers yellow. Ovary depressed : 
style subulate : stigma simple obtuse. Berry size of a black 
currant, purple, shining : seed .solitary, size and shape of a co-

Cissus alatus of Jaequin appears to me to be the present 
species, .and C. trifoliata of the same Author, to be our C. 
ACIDA.

Calyx sub-5-dentate. Petals 5 coherent at the 
apex, separating at the base like a calyptra and 
dropping off together. Stamens 5. Style 0. Berry 
2-celled, 4-seeded, with the cells and seeds frequently 
abortive. 
Leaves simple. — The common Grape, Vitis vinifera is very
