Tamarind fruit botanically is a type of fruit Pod (lomentum).
Tamarind (Tamarindus indica) is a leguminous tree bearing edible fruit that is probably indigenous to tropical Africa. The genus Tamarindus is monotypic, meaning that it contains only this species. It belongs to the family Fabaceae.

Herkogamy (or hercogamy) is the spatial separation of the anthers and stigma in hermaphroditic angiosperms. It is a common strategy for reducing self-fertilization.
In self-incompatible species, herkogamy may function primarily to reduce sexual interference, whereas, in self-compatible plants, it is usually considered an adaptive character that decreases the likelihood of self-pollination and increases the opportunity for outcrossing.
