Leaves of grapevine and maracuyá separated by relative node position.

Leaves are arranged from shoot base (mature, juvenile) to shoot tip (young, adult). Relative node positions are then assigned for each leaf with 1 being base and 0 being tip. Heteroblasty is evident for all species but is particularly striking in the maracuyá group. Species-to-species differences in leaf morphology is also more dramatic in the maracuyá group.
