Please ID this medicinal plant with pink/red flowers. Photo was taken in Sri Lanka in Sep 2012.

Can this be Rauvolfia serpentina?

Yes, it looks like Rauvolfia serpentina.

For me this looks like an Acanthaceae member

Does not look like R serpentina

May be Odontonema cuspidatum.

Garden ornamental for ID

Planted in archaeological park Chand Bagh Maula Ali, Hyderabad.

Photographed 25th June 2013.

Should be Odontonema strictum, common name Firespike as in FOI.

… is right. It is Odontonema strictum of Acanthaceae. This garden plant attracts bees, butterflies and birds (Humming bird). 

One important issue for me was whether it is a native species, which Odontonema strictum is’nt. it seems very difficult to find native ornamentals in our gardens and parks!

Please ID this small herbaceous medicinal plant with red flowers. Photo was taken in Sri Lanka in Oct 2012.

this is a plant of mexican origin, popular and … now naturalized in tropical americas… Odontonema cuspidatum of Family Acanthaceae

colloquially called the firespike flower
vaguely reminiscent of the matchstick flowers we have seen in specialty nurseries… s red stick like flowers and the name indicates the resemblance.   

Thanks … This is the same thing I have posted- Pls ID.Cochin.121114RT.Nov-4. 2 days back and identity suggested by … as Odontonema tubaeforme. Yes common name ‘Firespike’. The home owner -my friend-told me it was brought from SriLanka.
