The shape of the nutlet and the character of its coat are very varied. |
Typically four nutlets develop per calyx and time of nutlet maturation varies from 3-6 weeks in spring-blooming species to 2-4 weeks for fall-bloomers. |
This will, I think, help to fertilize the pistillate or nutlet blossoms on many of the trees. |
Fruit a capsule, berry, drupe or dry and indehiscent or a schizocarp, sometimes dicoccous, rarely a nutlet. |
The nutlet has become hard, rougher and more strongly ribbed. |
