inflorescence is cyathium, in which involucre fuse to form a cup surrounding a large achlamydous, pedicellate, tricarpellary, syncarpous female flower. Numerous centrifugally arranged male flowers surround the female flower.numerous centrifugally arranged male flowers surround the female flower.
cylindrical phylloclades are found which are modified aerial stems. Flowers are unisexual which develop acropetally and pollen tube enters the ovule through chalazal tissues
chalazogamy.
