Other botanical information  

Hibiscus comprises 200–300 species, mainly in the tropics and subtropics; many of them are grown as ornamentals. The estimated number of species varies because opinions differ about inclusion of several related groups of species in the genus. Hibiscus surattensis belongs to section Furcaria, a group of about 100 species which have in common a pergamentaceous calyx (rarely fleshy) with 10 strongly prominent veins, 5 running to the apices of the segments and bearing a nectary, and 5 running to the sinuses. Other species belonging to this section and used as a vegetable are Hibiscus acetosella L., Hibiscus asper Hook.f., Hibiscus cannabinus L., Hibiscus diversifolius Jacq., Hibiscus mechowii Garcke, Hibiscus noldeae Baker f., Hibiscus rostellatus Guill. & Perr. and Hibiscus sabdariffa L.
