verb[with object] (usually as adjective exserted) Biology
Cause to protrude:an exserted stigma...
On the basis of the phylogenic relationships, autogamous species most likely evolved from self-incompatibility ancestors that have exserted stigmas.
In flowers of short-styled individuals, the top of the stigma is located just above the midpoint of the corolla tube and stamens are slightly exserted.
All three subspecies are white flowering with a tubular corolla and a long style that exserts the stigma from the corolla tube.
Origin
Mid 17th century: from Latin exsert- 'put forth', from the verb exserere(see exert).
