is a plant species belonging to the family

" due to its shape that resembles the shape of human
female genitals

. 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'. Meanwhile on the other hand, the species name is derived from the name of the island where these
Linnaeus's specimens originated; which is the
Ternate Island located in
northern part of the Maluku Islands.
Distribution
This plant is native to
equatorial Asia, including locations in
South Asia and
Southeast Asia but has also been introduced to Africa, Australia and the Americas.
