Angled Sida (Sida acuta ??) from Satara

KAS Week::(Sida acuta-03/10/2012-NJ): Sida acuta (Sahadevi – in Marathi)

I can see three linear epicalyx below the calyx. Besides flower looks more like Malvastrum.

3 linear epicalyx and distinctive obliquely obovate petals clearly identify with Malvastrum coromanelianum, although leaves are narrower.

Can be Sida acuta also.

Malvaceae herb for ID :: MK 2017 Feb-01 : 3 posts by 2 authors. Attachments (6)

Please help me to identify this Malvaceae herb found in dry lakebed. Could this be Sida spinosa?
Date: October 2016
Alt.: 29 m asl

Location: Tiruvallur dist (near Chennai), TN

Thanks,  …  You can check in EFI also.

Closest I could found as per comparative images at Sida is Sida spinosa L. only.

However, images of leaves in your post look a bit longer compared to images in efi at Sida spinosa L.

I also think it is closer to images at Sida acuta Burm.f. rather than those at Sida spinosa L.

Any reasons or references ?
To me it looks different from images at Sida spinosa L.

It’s very variable based on habitat …,

the main reason is spine-like projections at axils,
if still have doubt wait for experts comments,
