ABSTRACT:

Seedlings of Araceae can be assigned to three basic types: type A with endosperm and a compact cotyledon, type B with endosperm and a cotyledonary hypophyll expanded to form an early photosythetic area, and type C with endospermless seeds and an enlarged, green storage cotyledon. The seedling morphology of 64 genera of the family is currently known. The distribution of the seedling types on a molecular tree is documented. Type B seedlings are restricted to Aroideae. The systematic value of seedling characters is discussed. Seedlings provide no decision about the position of Calla in the family.
