Nutlet

 

(also nucule), a single-seeded, indehiscent fruitlet of an apocarpous fruit (for example, in the buttercup). Sometimes other small single-seeded fruits (the paracarpous fruits of fumitory; the lysicarpous fruits of buckwheat), the fruits of Boraginaceae and Labiatae, and the mericarps of Euphorbiaceae are called nutlets.

The Russian term for nutlet, oreshek, is used to designate a nutgall, a spherical or fleshy node caused by insects on the leaves and stems of plants (for example, nutgall of oak).
