Thanks Ragjhu ji
I was waiting to see this, especially because of confusion in H. furcatus status now.
Hibiscus furcatus Wall. is the synonym of H. surattensis L., a name used in FBI and still holding true (fork has one spoon shaped appendage and one small erect linear branch; stipules large leafy ear-shaped; leaves 3-5-fid)
Hibiscus furcatus Roxb. described in FBI and now correctly known as H. hispidissimus Griff. (both forks linear; stipules lanceolate-oblong; leaves entire or 3-lobed)
Hibiscus furcatus Willd., a synonym of Hibiscus rostellatus Guill. & Perr. an African plant not found in India
Other expected species in India, cultivated or naturalised from this group (forked epicalyx segments) include.
Hibiscus radiatus Willd. epicalyx 8-10, with linear fork segments, stipules linear; leaves deeply 3-5 lobed.
Hibiscus acetosella: epicalyx 9-10, apically forked, leaves irregularly 3-5 lobed.
Hibiscus cannabinus looks similar to above two species but is distinct in deeply 3-7-parted leaves and importantly with epicalyx segments not being forked.
