‎Ruellia species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net)  Now all Indian Dipteracanthus fall under Ruellia only.

My guess is Ruellia suffruticosa Roxb., but I am not confident, for one more species, R. patula Jacq. needs to be considered. Attached here record by Haines. R. patula unlikely to be found in the region as per FBI and also that FBI thinks R. patula is similar to R. prostrata.

Thank you

Well, something more..... I missed the BSI checklist - http://efloraindia.nic.in/efloraindia/speciesList_PCL.action?resultType=genusWise&parent_Id=130&parent_Name=ruellia.

R. patula, I think, can be skipped - http://www.plantillustrations.org/illustration.php?id_illustration=130595&mobile=0&code_category_taxon=.

Instead, there is one R. pseudopatula in BSI - http://efloraindia.nic.in/efloraindia/speciesDesc_PCL.action?species_id=860. Please check probability - http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000393972

Looks like Ruellia sps only. Could be R.patula .  But not able to check all the characteristics from the photographs.

Attached here what had been identified, in this group, as Ruellia prostrata Poir. Flower colour usually not white, may turn whitish sometimes. In the 4th pic you see flower and foliaceous bract sizes.

Ruellia suffruticosa Roxb.	Ruellia patula Jacq.	Ruellia pseudopatula Ensermu
white, maybe pale-purple, corolla 50-57 mm long, 25-32 mm diam., narrow part of the tube 18-26 mm sepals 5-6.5 mm ref. Haines	pale blue-lilac or pale purple, corolla 25-38 mm long, lower cylindrical portion is shorter than the upper; style 16-19 mm long should be equal to next sp. ref. Ensermu Kelbessass	pure white, corolla 45-60 mm long, lower cylindrical portion of the tube is longer than the enlarged upper portion; style 35-40 mm calyx tube 1-1.5mm, lobes 4-5mm ref. Ensermu Kelbessass

This species in this thread is Ruellia pseudopatula Ensermu

Thank you

Thank you very much Sir for your kind response. But I expected you or other member(s) would ask/query why your specimen can not be R. suffruticosa Roxb.! More so because petals and sepals are more or less of equal length in both the spp., (R. suffruticosa Roxb. and R. pseudopatula Ensermu); including narrower to inflated part of corolla tube!

I am explaining why I choose one of the above two ids. In suffruticosa, leaves are 2-5 inch (50-127 mm), while in pseudopatula leaves are 15-30 x 10-20 mm. Comparing the flower size with the leaves in the attached photographs of this specimen I think it would go more with R. pseudopatula Ensermu.

Thank you
