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.

Does not matches with images at Hibiscus surattensis

Leaves and stipules can not be seen, which are diagnostic.

May be Hibiscus hispidissimus as per keys at BSI Flora of India

Yes I agree with you; the prickles on the second image are indicative of H.hispidissimus
