Term:
Androecium (pl. = androecia)
Androecium (pl. = androecia)
Definition:
The male part of the flower.
The male part of the flower.
Notes:
In the flower of neotropical Lecythidaceae, the androecium may be actinmorphic or zygomorphic. The former consists of a staminal tube and associated stamens while the later usually has a staminal ring with stamens, a ligule, and a hood with various combinations of staminodes, vestigial stamens, and nectar-producing vestigial stamens. The only zygomorphic-flowered exceptions are Couroupita nicaraguarensis which lacks a hood and all species of Cariniana whick lack a staminal ring and a hood but do have a prolongation from the staminal tube and are, thus, also zygomorphic.
