Please help me to identify this slender Acanthaceae plant found near roadside in evergreen forest.
Height: 3 feet
Leaf: 10cm long
Flower: 1.5cm long
Date: 25 Aug 2012
Place: Valparai, TN
Habitat: Evergreen forest

This looks like a species of Andrographis possibly A. paniculata [Creat].

Can you check it with Andrographis atropurpurea and its allies

I too think that this could be A. atropurpurea.

It could be A.paniculata

I don’t think this is Andrographis paniculata; because A.paniculata have smaller flowers.

The size of the flowers mentioned here is 1.5 cms which conforms with that of A.paniculata [approx. 2 cms] as seen in my photographs at this link

Oh yes …, just now I noticed your plant and that it resembles much alike my picture. Thanks for the input.

This plant is Andrographis macrobotrys Nees as confirmed by … of BSI, Southern Circle. Now merged with A.ceylanica. The plant is distributed in Western Ghats and Sri Lanka.
A. atropurpurea have clasping auricle shaped leaf-base. Yet both are evergreen species.

Andrographis atropurpurea (Dennst.) Alston
