peduncle

Large emergent peduncle of Agave, with bracts and branches at nodes.

In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fertilisation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphyll) at nodes. The main axis of an inflorescence above the peduncle is the rachis, which hosts flowers (as opposed to directly on the peduncle).
