Bush Sorrel, Wild Sour, Bush Althea • Mizo: Sehnap • Tamil: Kashlikirai, kattuppuliccai • Malayalam: Assam susor • Telugu: Mullugogu • Kannada: mullu gogu;
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.

Hibiscus straggler for identification 190114MK002 : Attachments (7).  4 posts by 3 authors.

Please help me in identifying this Malvaceae straggler.
Flower: yellow colour
Habitat: moist deciduous forest
Location: Kanyakumari forest division, TN
Alt: 450 m asl
Date: 16 January 2014

Hibiscus surattensis I hope. Auriculate stipules and spoon shaped outer branch of epicalyx are distinctive.

Agree with … Hibiscus surattensis L. a common strangler in forest outskirts

Thanks a lot for the identification

Mumbai, MH :: Hibiscus for ID :: ARK2020-022 : 13 posts by 4 authors. Attachments (6)- around 700 kb each. 

Saw this Hibiscus in a marshy area in Charkop, Mumbai, MH in October 2019.

Requested to please provide ID. Is this H. surattensis or H. hispidissimus or any other?

I guess it is matching.

Saroj ji, I am not sure of the ID. Is this H. surattensis?

Other recipients:
I guess it looks more close to H. hispidissimus but rather difficult to confirm it. Thank you. Saroj Kasaju

Other recipients:
I too strongly think, it is Hibiscus hispidissimus. … because the plant is densely pubescent … description referred at Herbarium JCB. versus H. surattensis – with sparse minute prickles, otherwise glabrous … description referred at Herbarium

There are other differences too. Let us wait for more comments.

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

Based on the keys above and stipules seen in 1st image, it should be H. surattensis 

Stem prickles are also without basal tubercle.

Pl. also see FOC illustration. 

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.
Thanks … for the analysis and reaching to ID.

Thanks … for resolving this. I think … too had suggested H. surattensis on FB.
