May be, but two pics are of Jasminum.

Please ID this small herbaceous ornamental plant with violet flowers. Photo was taken from a park in Sri Lanka in April 2012.


Should be Pseuderanthemum graciliflorum of Acanthaceae.


Is there a key for the genus Pseuderanthemum

there are more than 120 species… how does one diagnose a species from so many so closely resembling members? from one photo that may not have most of the differentiating features identified…

I am confused and worried…


This is a very rare ornamental plant also known as Blue Twilight, Blue Crossandra, Florida Twilight .


Key to few species can be found at –

Key no. 10 -> 17 -> 21 -> 22 -> 24 ->26 -> 27 = Pseuderanthemum


you put in a lot of work.. I’ll go thru and get back
