The ontogeny and morphology of the tuber of Gloriosa superba are inves
tigated. This perennial organ (tuber) was previously classified as a r
hizome, root stock or tuber. We consider this organ to be a hypopodial
tuber mostly consisting of two metamorphous hypopodia with an apical
bud enveloped by a prophyll, all covered by the remains of leaf bases.
Separation of the mostly bilobed hypopodial tubers produced a higher
percentage of flowering plants than undivided tubers.
