Clitoria

Clitoria is a genus of mainly tropical and subtropical, insect-pollinated flowering pea vines.

Naming of the genus
This genus was named after the human clitoris, for the flowers bear a resemblance to the vulva. The first reference to the genus, which includes an illustration of the plant, was made in 1678 by Jakób Breyne, a Polish naturalist, who described it as Flos clitoridis ternatensibus, meaning 'Ternatean flower of the clitoris'. Many vernacular names of these flowers in different languages are similarly based on references to female external genitalia.

Controversies existed in the past among botanists regarding the good taste of the naming of the genus. The analogy drew sharp criticism from botanists such as James Edward Smith in 1807, Amos Eaton in 1817, Michel Étienne Descourtilz in 1826, and Eaton and Wright in 1840. Some less explicit alternatives, like Vexillaria (Eaton 1817) and Nauchea (Descourtilz 1826), were proposed, but they failed to prosper, and the name Clitoria has survived to this day.
