On 17/8/08 in Talakona forest, AP. Is it some Hygrophila species?
it seems to be justicia procumbens
The flower is Justicia procumbens.
Thanks, ... for ID.
This link gives Justicia simplex as Justicia procumbens var. simplex:
Here is a link for details of Justicia procumbens (Water willow): http://www.hear.org/pier/species/justicia_procumbens.htm 
Rostellularia japonica (Thumb.) Ellis. Details as below:
In the description of Justicia japonica at Flora of Pakistan, the flower is described to be 2-lipped, with both the lips about 3 mm.
In your flower, the lower lip is much larger than the upper one. ...
It appears to be Justicia diffusa as per keys available at:
Flora of Madhya Pradesh: Chhatarpur and Damoh By G. P. Roy, B. K. Shukla, Bhaskar Datt (Description & Keys- Justicia diffusa, simplex, quinqueangularis var. quinqueangularis, quinqueangularis var. peploides)
Pl. confirm.

Justicia ¿ procumbens ?
The tiny-flowered Justicia has confused me often; taking opportunity of this fortnight to get most of my sightings validated. Some of the photosets may prove insufficient for validation.

I think this may be the same one as in this post.
They were clicked about 2 months apart in different forests outside Bangalore.
Family: Acanthaceae
Date: October, 2014
Place: Nandi Hills, Bangalore, Karnataka
Habit: Herb

Justicia- species in eFIoraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ efloras/ books etc., where ever available)


This species has to be Justicia diffusa Willd. on account of:
1) Woody herb
2) Branchlets striate
3) Calyx 4
4) Bracts much shorter than calyx
5) Bracts ovate with scarious margin
6) Oblong and glabrous capsule
These characters match the following description and herbarium.

Thanks ..., learning a very complicated genus from your threads, specially thanks for explaining salient features.
Thank you sir.
I have brought this plant home from the forest to grow and examine with a hand lens and was hence able to carefully look at all the characters.
Unless I do this for all the other Justicia sp. I doubt if they can be identified due to the size of the plant and its parts!
I'm still doing without glasses, but time has come to have a pair!
