a scape is a single internode. It might comprise an entire peduncle with just one flower (e.g. Tulipa) or just the basal internode of a peduncle. This is in contrast to the typical compound peduncle, which morphologically speaking is derived from a branch, or from an entire shoot.

A single scape may bear a single flower or many, depending on the species. When it bears more than one flower, there is the terminal part of an inflorescence on top, as in Amaryllis. Compare this
