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, 

 submembranaceous, 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,

Leaves simple. — The common Grape, Vitis vinifera is very
