sida rhombiifolia: it is growing profusely, unlike the other sidas
This is Sida retusa.
Malvaceae week: RVS2: Sida alnifolia:
you are partially correct: it is also treated as S. rhombifolia subsp. retusa. Now it is the typical variety under S. alnifolia.
This key from eFlora of China should be useful
Flower ID request – RK1 – 10-Oct-2012:
This is Sida retusa. Please check the archives of this group for my photographs of this.
Thanks a lot for the quick identification. I checked the archives and found one thread with your photos of this plant and it looks identical.
I am also of the opinion that all pics do not belong to same plant they of course have resemblance…but the first image rk_for-id_001_1.jpg and third picture rk_for-id_001_3.jpg are of same plant, rest are distinct..
I agree with … id: Sida retusa (the accepted name, however, is Sida alnifolia). As assured by .., I think all the pictures are of the same plant, too (due to similar stem color, indumentum, and the lower typically-retuse leaves can be seen in the backdrop of the first picture). A picture of whole plant may be helpful.
Many thanks for posting this interesting plant. This is the beauty of the group. If there is one reply there might be another with reasoning to it ultimately helping the ID of plants where often the flower looks same in a genus but species may be different. The leaves are characteristic here which helps in ID.
Thanks a million … & … for your responses. I’m certain that the photographs are from one plant only. Thanks again for your explanation about the varitiaon in leaf shape. I have attached one more photo where both kinds of leaves are seen.
Thanks … for sharing yet another ‘character photograph’! It speaks for itself…
Sending one more photograph of mine.

Thanks … You must be right. Need to check again from my side.
Then link in our Sida page for reference Malvaceae of Southern Peninsular India: A Taxonomic Monograph V. V. Sivarajan, A. K. Pradeep – 1996- Great details- from p.228-
The key starts on page 254 .. but then it does not show page 265…
for the key itself and pages 267 , 268, 270 and 271
Can any member please provide e a photocopy of the pages for us here so it could be included int he data base and it would help during this malvaceae learning process.
Can you please help ID this small plant, growing in the wild, from Kerala? A friend said that it’s Kurunthotti, a plant widely used in Ayurveda. Sida cordifolia.
But Sida cordifolia leaves look different online.
This plant is 40-50 cms tall. Unfortunately, it did not have any flowers or buds.
Sida rhomboidea Roxb. ex Fleming !!
I think Sida alnifolia L. as per Keys and details to the species of genus Sida L. in Maharashtra as per A Synopsis of the genus Sida L. (Malvaceae) from Maharashtra, India– Gajanan M. TAMBDE, Ramchandra D. GORE and Milind M. SARDESAI- Taiwania 61(3): 243‒252, 2016

Check Sida rhombifolia subspecies rhombifolia
I think it is close to the images at Sida alnifolia L. and as per the shape of the mericarps as per A Synopsis of the genus Sida L. (Malvaceae) from Maharashtra, India– Gajanan M. TAMBDE, Ramchandra D. GORE and Milind M. SARDESAI- Taiwania 61(3): 243‒252, 2016 and as per Malvaceae of Southern Peninsular India: A Taxonomic Monograph V. V. Sivarajan, A. K. Pradeep – 1996.
However, here I only see 5 mericarps in a fruit, while A Synopsis of the genus Sida L. (Malvaceae) from Maharashtra, India mentions 7 to 10. Flora of China says mericarps 6 to 8.
Can you check the no. of mericarps in a fruit again?
Yes, it is Sida alnifolia, seeds are 05 to 07 numbers,
