生叶

Unlike a leaf, a cladode has buds on its surface.

但节与节间明显，节上能分枝，。

Basal leaves rosulate, simple, usually pinnately lobed, lyrate, or runcinate, rarely entire or toothed.

莲座状，单的基，羽状浅裂的通常，大头羽裂，倒向羽裂的，很少全缘齿。

Basal leaves decussate; middle stem leaves opposite; distal stem leaves alternate; Inflorescence paniculiform with cymose branches.

基交对；中间茎对；上部茎；序圆锥序状的具聚伞状的分枝。
