stipule

Styles 2, distinct.—Homely little weeds, with awl-shaped leaves, obscure greenish clustered flowers, and no stipules.

The stipules are between the leaf-stalks, each consisting of two lateral ones united, or rarely with the tips free.

Here we have another modification, a development of the "stipule," that tiny pointed growth common to many leaves, and particularly notable at the base of a rose leaf.

Leaves.—Usually alternate; compound; with stipules; the latter sometimes transformed into thorns or tendrils.

The leaves when borne on an elongated stem are arranged alternately and have no stipules.
