Type: Herb. Hermann, Vol. III. fol. 4. Linn. n. 260 (BM!).
Distribution: It has been said to be native to China. But its native home is still unknown. It is presumed that it originated in East Africa as the related species Hibiscus schizopetalus L. was first collected in wild stage in this area (Borssum Waalkes 1966).
It is most extensively cultivated as an ornamental plant and occurs in many forms in Pakistan.
