Dipteracanthus prostratus.

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

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

Ruellia tuberosa
For validation
Seen on Vetal tekdi Pune last week (posted on 7.8.2010).
A small shrub. Flowers 4-5 cm.
Leaves and other characters as seen


Ruellia tuberosa IS THE CALL FROM ME!!


Dipteracanthus species!


Dipteracanthus patulus syn Ruellia patula. R. tuberosa is a garden escape.


Still doubtful whether it is Ruellia prostrata or Ruellia tuberosa.
I think it appears more like Dipteracanthus prostatus Syn. Ruellia prostrata

Erect shrublet with hoary shoots. Flowers pale-white. Capsule glabrous, 8-10-seeded 1 Ruellia patula

Yes.


I think Ruellia longepetiolata (Oerst.) Hemsl. as per images and details herein.


Sorry, Correct id is Ruellia patula Jacq. as per images and details herein.

Place, Altitude, GPS- Codisia Road, Coimbatore, Near Air Port.
Habitat- Urban. along the road side.
Plant Habit- small herb
Flowers : Pink colour,

Is it Ruellia geminiflora syn: Ruellia humilis of Acanthaceae family?


I think it is Dipteracanthus prostratus


The id by … is correct, I think.
Most of the species of Dipteracanthus are synonyms of Ruellia now.


Thanks …, but theplantlist says it is an unresolved name…as far as I know only one sp of Ruellia, i.e. R. tuberosa is naturalized in India. All other wild species come under Dipteracanthus. But, I am not sure of the current name for this taxon, you may be right in saying Ruellia.


Thank you … for pointing out my mistake.
Only Ruellia tuberosa is naturalized in India.
Here I think the leaves are smaller than that of Dipteracanthus prostratus. It is not very clear whether the plant is prostrate or erect from the picture.
Any chance of Ruellia patula (Syn: Dipteracanthus patulus)?


I guess close to Ruellia patula Jacq. !  Dipteracanthus patulus


Yes, I agree as per images at Ruellia patula Jacq.


I too agree with …

Validate and identify Ruellia spp


Ruellia species so far in efi. 


Could be Ruellia malacosperma. However it is difficult to  confirme as the leaves in your photographs is not very clear


Thanks, … Ruellia malacosperma Greenm. is a synonym of Ruellia simplex C.Wright


It seems to be Dipteracanthus patulus (Jacq.) Nees (= Ruellia patula Jacq.) with white flower, erect habit, obtuse leaves, pubescent capsule are the supporting features.


It may be either Dipteracanthus (≈ Ruellia) patulus or D. suffruticosus which I think has white flowers, too.


THE plant is wild, the photos were taken on 27-6-2013 at 7 am Nandgaon Nasik.


I think Ruellia patula Jacq. as per images and details herein.
