Heterocarpy

from Wikipedia, the free encyclopedia

Heterocarpy , also different fruitiness , is a term from botany and means the occurrence of differently shaped fruits.

The term describes the fact that in some plant species the same individual forms different types of fruit , which are then also spread in different ways. Some types of dandelion ( leontodon ) develop achenes with and without a fringe of hair ( pappus ) that helps the wind to spread . Heterocarp fruits are also found in the marigold ( calendula ) (outer longer, inner shorter and more curved).
