生叶

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

但节与节间明显，节上能分枝，生叶和开花。

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

莲座状，单基生叶，羽状浅裂，大头羽裂，倒向羽裂，很少全缘齿。

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

基生叶生；中间茎生叶生；上部茎生叶生；花序圆锥花序状具聚伞状分枝。
