Dipteracanthus prostratus.

I think more close Ruellia patula Jacq. rather than those at Ruellia prostrata Poir.

Ruellia ? SN 31519 : 9 posts by 4 authors. Attachments (2)
Wild herb in the coastal sand; Dwaraka (Gujarat)

Ruellia patula ?? 

I am doubtful with images at Ruellia patula

It also seems somewhat similar to Ruellia pseudopatula, but does not seem to have distribution in the area.

Any other close species ?


Noted. You are right 

As per Flora of Rajasthan it Is Ruellia patula var. alba (Saxton) Bhandari,
Flowers closed in sunlight. 

Almost close.

Yes, may be Ruellia patula only as per details and references herein.

Ruellia ...close to Ruellia patula ...can we see calyx ?
Thank you very much Sir.
Unfortunately I have only these two images.

Thanks, ..., for the id.
I also think close to Ruellia patula as per comparative images at Ruellia

agree with ...
Still, narrow part of tube and calyx essential for confirmation

Small herb Clicked on kondapalli fort, Andhra Pradesh 2015 May 
Check Dipteracanthus species
Dipteracanthus patulus
Dipteracanthus prostratus (Poir.) Nees ?? 

I agree with … for Ruellia patula Jacq. rather than Ruellia prostrata Poir. as per images and details herein.

Yes it's Ruellia patula,
I too agree with you, …
R. patula or R. pseudopatula
White. In image 'original2' narrow tube does look longer than wide tube, and calyx is not seen hinting its very small size ... all points hinting at R. pseudopatula

TO me its a toss up between R. patula and R. psuedopatula since as a scientists we should need a more precise way of measuring and judging the length of the tubes and since the maker of the pic has torn it from the plant anyway, it should be stripped of the leaves and sepals and put alongside a ruler in the photo.
Please look at … submissions. we need to emulate his photo techniques for details
I will go with Ruellia patula rather than Ruellia pseudopatula as per keys and details herein.
