Sorry that I ignored the important character.(I was looking at the picture in my mobile!)

It must be a species of Rungia.

This should be Justicia pectinata as per discussions at Sorting Rungia species 

[dr.rakesh Singh]

OMG specimen !!!!!! And I disagree . 

 This needs to be investigated . 

Here is why .....

Leaves very broad ,

Peduncles to spikes loooong ! 

Spikes lax . 

It seems flowers are white and bigger than typical J. pectinata . 

I would like to see hairs on fertile bracts .  

It seems this belongs outside parviflora/pectinata complex .

Thanks, Rakesh ji,

You have wonderful observatory power.

This should be Justicia crenatifolia

I do not agree with Rungia crenatifolia , not matching with images in Justicia crenatifolia

Rungia sisparensis is a possibility .

Forwarding again for Id assistance please.

To me looks different from Rungia sisparensis  as per GBIF  High resolution specimen  Flora of Karnataka  POWO  IBIS Flora

Thanks, Sasidharan ji,

But it is not Rungia parviflora as per discussions at Sorting Rungia species

I am reproducing the details in Flora of British India. Pl. check. 

Top portion of it, I am copying and pasting from IBIS Flora as below:

Nees in Wall. Pl. As. Rar. iii. 110, and in DC. Prodr. xi. 469, excl. syn. ; leaves small ovate or lanceolate nearly glabrous, bracts dimorphic barren elliptic or oblong subobtuse striate hardly margined, fertile obovate glabrous scarious-margined ciliate, bracteoles elliptic scarcely acute, corolla 1/4 in. R. repens, T. Anders, in Journ. Linn. Soc. ix. 518 partly, not of Nees. R. longifolia, Bedd. Ic. Pl. Ind. Or. t. 266, not of Nees.

S. DECCAN PENINSULA ; Weight (2011, 2285 Herb. Propr.). CEYLON ; Thwaites (C. P., nn. 257, 3354).

A small, ramous weed. Lower leaves 1 by 1/4-1/2 in., petioled, ovate, upper narrow sometimes linear. Spikes 3/4 by 1/4 in., nearly all terminal, markedly 1-sided ; barren bracts not cuspidate. Capsule 1/5 in. ; seeds small, minutely verrucose.—This, the typical R. parviflora, Nees, appears a very rare plant ; Nees, however, referred numerous specimens with the fertile bracts hairy all over to R. parviflora, but which are R. pectinata, Nees, as far as the description goes.

Lower portion of it, I am copying and pasting from IBIS Flora as below:

Revision of Rungia parviflora var. pectinata (Nees) C.B.Clarke from Fri, 2014-03-07 13:48     

flowerless bracts mucronate often cuspidate flowering hairy. R. pectinata, Nees in DC. Prodr. xi. 470 ; Wight Ic. t. 1547 ; T. Anders, in Journ. Linn. Soc. ix. 517. R. parviflora, Nees l. c. partly ; Griff. Notul, iv. 144 ; Dalz. & Gibs. Bomb. Fl. 195. R. polygonoides, Nees in Wall. Pl. As. Rar. Hi. 110, and Cat. 7181, and in DC. Prodr. xi. 471 ; Dalz. & Gibs. Bomb. Fl. 196. Justicia pectinata, Linn. Amoen. Acad. iv. 299 ; Lamk. Ill. i. t. 12, fig. 3 ; Roxb. Corom. Pl. ii. 29, t. 153, and Fl. Ind. i. 133 ; Wall. Cat. 2458. J. parviflora, Retz Obs. v. 9. J. infracta, Vahl Enum. i. 155.—Throughout India, from the Himalaya to Ceylon and Pegu, a universal weed.—Usually ramous. Leaves 3/4 by 1/3 in. ; petiole 1/8 in. Spikes 1 by 1/4 in., terminal and axillary, clustered, subsessile, distinctly 1-sided ; barren bracts 1/6 by 1/12 in., scarcely margined ; fertile 1/10 in. diam., orbicular, apiculate, scarious- marginate, hairy on back as well as on margins ; bracteoles 1/10 in., elliptic, subacute. Calyx 1/12 in. ; segments linear-lanceolate, pubescent. Corolla blue or whiteish, upper lip short. Anther-cells superposed, lower white-tailed.—The area of this abundant plant should perhaps be extended to Java, &c., but the examples thence (Dicliptera coerulea, Blume Bijd. 791) differ considerably from all the Indian material, which is very uniform in character, the size of the heads and bracts varying a little.

Thus from above flowerless bracts mucronate often cuspidate flowering hairy for R.pectinata and flowerless bracts subobtuse for R. parviflora being the key.

[dr.rakesh Singh]

Garg sir , unfortunately we do not have authentic material/images online for many more relatively uncommon species .  

There are many lesser known species of "Rungia" from Kerala like R. apiculata , R. linifolia , R. sisparensis , R. wightiana , R. laeta ... with precious little online . 

Yesterday there was a post on facebook which I have never seen earlier , is not in efi and other online floras . I have tagged you . 

[J.M. Garg]

Thanks, Rakesh ji, 

In that case, we have to look at the Flora of British India and GBIF. 

Hopefully somebody from Kerala also helps us.

Thanks a lot, Sasidharan ji.

Hi, Rakesh ji,

To me it looks like Justicia crenatifolia only as per High resolution specimen at GBIF.

Image is not clear, which may be causing a little bit of confusion.

There may be variation in the habit as we have seen in other species like Justicia pectinate.

[surajit koley]

Threads/posts placed in Justicia crenatifolia page at eFI is still confusing to me. So, I cannot comment on a species which is still unclear to me!

Thank you.

Surajit Koley
