Corm of a Crocus
The investing sheaths or dead leaf-bases striped off. The faint cross-lines represent the scars, where the leaves were attached, i.e. the nodes: the spaces between are the internodes. The exhausted corm of the previous year is underneath; forming ones for next year on the summit and sides.
