Hibiscus hispidissimus Griff. (Flora of China gives the following keys:

7 (6) Stipules auriculate; stem prickles without basal tubercle, curved. 20 H. surattensis
+ Stipules narrowly lanceolate; stem prickles with prominent basal tubercle, straight. 21 H. hispidissimus

I checked all post in efi site at Hibiscus hispidissimus Griff. and Hibiscus surattensis L. – these seems to be OK. Determination based on stem prickles may be confusing. So better to go with the stipules.
Keys in the book in Flora of Karnataka bases keys between the two only on Stipules and not on stem prickles.)

As per efi thread :
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.

Help building a key for genus Hibiscus:

Our website already has keys for Indian species of Solanum, Cassia, Senna and Chamaecrista. It is proposed to build a similar key for the genus. The first step towards this is preparing an updated list of Indian species (Both wild as well as cultivated, as several cultivated herbs often run as escape and trees and shrubs are often difficult to place as wild or planted, especially because of plantation drives in the recent years). I am sharing a preliminary list. Kindly suggest additions or corrections.
1. Abelmoschus crinitus Wall. (syn: Hibiscus cancellatus Roxb. (non L.); Hibiscus crinitus (Wall.) G. Don)
2. Abelmoschus esculentus (L. Moench. (syn: Hibiscus esculentus L.)
3. Abelmoschus ficulneus (L.) Wight & Arnott ex Wight (syn: Hibiscus ficulneus L.)
4. Abelmoschus manihot (L.) Medik (syn: Hibiscus manihot L.)
5. Abelmoschus manihot subsp. tetraphyllus (Roxb.) Borss. Waalkes. (syn: Hibiscus tetraphyllus Roxb)
6. Abelmoschus moschatus Medic. (syn: Hibiscus abelmoschus L.) + var. multiformis , var. betulifolius
7. Abelmoschus pungens (Roxb.) Voight. (syn: Hibiscus pungens Roxb.)
8. Hibiscus acetosella Welw. ex Hiern. (occurrence in India??)
9. Hibiscus angulosus Mast., + var. grandiflorus Thw., var. purpureus Thw.
10. Hibiscus aristivalvis Garcke (syn: Hibiscus intermedius A. Rich.) (is a synonym of Hibiscus palmatus Forssk.)
11. Hibiscus caesius Garcke (syn: Hibiscus gibsoni Stocks ex Harv.)
12. Hibiscus canescens Heyne
13. Hibiscus cannabinus L.
14. Hibiscus diversifolius Jacq.
15. Hibiscus floccosus Mast
16. Hibiscus fragrans Roxb.
17. Hibiscus hirtus L.
18. Hibiscus hispidissimus (syn: Hibiscus furcatus Roxb.; H. aculeatus Roxb. (non. Walter, nor G. Don))
19. Hibiscus hostilis Wall. (synonymous with Abelmoschus hostilis (Wall. ex Mast.) M.S.Khan & M.S.Hussain)
20. Hibiscus indicus (Burm.) Hochr. (syn: H. venustus Bl.; Alcea indica Burm.)
21. Hibiscus lobatus (Murray) O. Kuntze (syn: Hibiscus solandra L’Her).
22. Hibiscus lunariifolius Willd.
23. Hibiscus macrophyllus Roxb. ex Hornem.
24. Hibiscus micranthus L.
25. Hibiscus mutabilis L.
26. Hibiscus obtusilobus Garcke (syn: Hibiscus punctatus Dalzell)
27. Hibiscus panduraeformis Burm.f
28. Hibiscus platanifolius (Willd.) Sweet (syn: Hibiscus collinus Roxb.)
29. Hibiscus pedunculatus L.f.
30. Hibiscus procerus Wall.
31. Hibiscus purpureus Forssk.
32. Hibiscus radiatus Cav. (syn: H. radiatus Willd. ex Roxb.; H. lindleyi Wall.)
33. Hibiscus rosa-sinensis L.
34. Hibiscus rugosus Mast.
35. Hibiscus sabdariffa L.
36. Hibiscus scandens Roxb
37. Hibiscus schizopetalus (Dyer) Hook.f.
38. Hibiscus scindicus Stocks (Occurrence in India)??
39 Hibiscus surattensis L.
40. Hibiscus syriacus L.
41. Hibiscus tiliaceus L. subsp. tiliaceous
42. Hibiscus tiliaceus L. subsp. hastatus (L.f.) Borss. Waalk.
43. Hibiscus tricuspis Banks (is a synonym of Talipariti tiliaceum (L.) Fryxell)
44. Hibiscus trionum L.
45. Hibiscus vitifolius L. (syn: Fioria vitifolia (L.) Matt.; Kosteletzkya vitifolia (L.) M.R.Almeida & N.Patil)

Thanks … for the initiative. The list is exhaustive!

I think Abelmoschus tuberculatus Pal & Singh and Abelmoschus moschatus subsp. tuberosus (Span.) Borss. Waalk. may be added to the list (Ref. GRIN).
I am not sure of the current status of Abelmoschus manihot subsp. tetraphyllus var. megaspermus Hemadri
And, for the name Hibiscus angulosus in the list, Abelmoschus angulosus Wall. ex Wight & Arn. seem to be the accepted name (GRIN & TPL).


Thanks for the useful information … I will surely incorporate it.

Hibiscus : 1 post by 1 author.

I have updated eFI (efloraofindia) page on Hibiscus

Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.

Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.

Any comments are welcome.


Further updated the Hibiscus page.

Pl. go through Hibiscus page with images of species (done by) in efloraofindia.

If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice.

Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know
