Spadix
In botany, a spadix is a type of spike, an inflorescence with small unisexual flowers crowded on a thick, long, fleshy peduncle. To avoid self-fertilization, the female flowers are usually arranged towards the lower part, with the male ones on the upper part and a stigma that stops being receptive when the pollen is released. They also usually have a spathe, a large, herbaceous bract, usually conspicuous and solitary, surrounding or partially enclosing the spadix from below.
This type of inflorescence occurs in certain Liliopsids (Monocotyledons), especially in members of the Araceae family, which is why they were previously called spadicifloras.. The flower >Anthurium is a typical spadix with a large, showy spathe. That of Amorphophallus titanum is often cited as "the largest flower", although it is actually an inflorescence. colocasia, aroids, maize, and palms (which have a compound spadix, with a branched axis and covered by a rigid boat-shaped hood, as in Cocos nucifera).
