Justicia crenatifolia J. R. I. Wood, nom. nov. (Replaced name: Rungia crenata T. Anderson, J. Linn. Soc., Bot. 9: 518. 1867, non Justicia crenata Pohl ex Nees, Prodr. [A. P. de Candolle]) as per New Names and Combinations in Indian Acanthaceae by John R. I. Wood- Novon: A Journal for Botanical Nomenclature 23(3):385-395. 2014;
Common name: Toothed Rungia
T. Anders, in Journ. Linn. Soc. v. 9 (1867) p. 518. An erect branched herb 1-1.1/2 ft. high ; stems and branches slender, terete or obscurely quadrangular, glabrous or nearly so. Leaves 1-2.1/2 by 1/2-1 in., elliptic-lanceolate, subacute, lineolate, sparsely hairy with hairs often bulbous-based, base acute ; petioles 1/4-3/8 in. long, hairy. Flowers in dense 1-sided spikes 3/4-1 by 5/8 in., terminal or axillary, sessile or pedunculate ; bracts on one side of the spike, dimorphic, the barren bracts alternate, in 2 opposite rows, foliaceous, 1/3-1/2 by 1/10-1/8 in., elliptic-oblong or somewhat obovate, densely softly hairy, strongly nerved, mucronate, often with a narrow scarious margin on the lower edge leaching about 1/2-way up from the base, the fertile bracts 1/6 by 1/10 in. (including the scarious margin), broadly obovate, mucronate, pubescent, with a broad scarious margin ; bracteoles 1/6 in. long, eiliptic-oblong, concave, pubescent, with scarious ciliolate margins. Calyx densely hairy, 1/6 in. long, divided nearly to the base ; segments linear-lanceolate. Corolla blue, 1/2 in. long, hairy outside ; upper lip rather less than 1/8 in. long, broadly ovate, acutely acuminate ; lower lip nearly 1/6 in. long, obovate, with 3 short obtuse lobes, the middle lobe the narrowest. Filaments glabrous ; lower cell of anthers with an obtuse white ap¬pendage. Capsules 1/10-1/8 in. long, ovoid, acute, pubescent at the apex, compressed, the 2 flat faces scarious, the narrow edge hard, white, shining. Seeds 1/20 by 1/30 in., ellipsoid. Fl. B. I. v. 4, p. 547 ; Woodr. in Journ. Bomb. Nat. v. 12 (1899) p. 358.

Seen this small herb at “Anshi Ghat, North Karnataka”.
Pls help me for Identifying Justicia sp. : Attachments (1). 4 posts by 3 authors.
Any body pls help me for correct nomenclature of Justicia sp. from Kottayam district of Kerala
Could be J. simplex.
Look the secund inflorescence, it represents Rungia
Sorry that I ignored the important character (I was looking at the picture in my mobile!)
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, …, 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.
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.
…, unfortunately we do not have authentic material/images online for many more relatively uncommon species.
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 pectinata.
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!

Justicia , Images not clear !
I think close to images at Justicia crenatifolia
