The stem of this plant looks cylindrical to me, Lamiaceae has a square stem ...... can please validate from the original photos where my observation is right?
I checked with other photos. Not able to conclude but as u said, it does look some what cylindrical. A close up of stem would have helped us.
I was initially thinking that it could be some Mentha sp.
As you said I am also confirmed that the stem is cylindrical and if it is so then Mentha sp can be ruled out because it has a square [4-angled] stem as far as I know. Most of the Lamiaceae members have square stem which is diagonistic character if the family. But I am referring a name because the stem can be 4-angled but due to photographic angle its not visible. then i will say.......
Mentha asiatica Borissova Bekrjasheva, Bot. Mater. Gerb. Bot. Inst. Komorova Akad. Nauk S.S.S.R. 6: 280. 1954.
Herbs rhizomatous, perennial. Stems erect, (30-)50-120(-150) cm, few branched, densely minutely tomentose. Petiole 0.1-0.5 mm; leaf blade oblong or elliptic to oblong-lanceolate, 3-8 × 1-2.5 cm, sometimes folded and curved downward, sometimes glaucous, appressed crisped minutely tomentose, glandular, base rounded to broadly cuneate, margin remotely unequal dentate, apex acute. Verticillasters in terminal cylindric spikes 3-8 × 1-1.4 cm; bracts linear to subulate, 5-7 mm; bracteoles subulate, nearly as long as calyx. Pedicel ca. 1 mm. Calyx ± purple-red, campanulate to funnelform, 1.5-2 mm, appressed pubescent, obscurely veined; teeth linear, close together in fruit. Corolla purple-red, 4-5 mm, pilose, tube gradually dilated, lobes ca. 1 mm; upper lobe oblong-ovate, ca. 2 × 1.5 mm, apex emarginate. Nutlets brown, ca. 1 mm, apex pilose, pitted. Fl. Jul-Aug, fr. Aug-Oct.
I find most character of this plant matches with with your specimen hence I am suggestion it. Characters which I have found common i coloured them in blue with bold letter please donot Take it otherwise I have only done this so that you can try to compare them with the original photos. Kindly validate ot wait for more better suggestions by experts.
I also agree with you for Mentha asiatica color of corrlla and calyx and some other characters of the photographs match with the description of the said sp. Hope the id is correct.
I also hope for the best!! This plant made me go through several floras and now if it is wrong then I will be extremely sad !!
Perhaps you may not have to be sad, it is closest call. I have seen a lot of M. longifolia (from which it is not very distinct) in Kashmir, the only thing which worries me that the inflorescence is unusually long in in ourplant today.
Any possibility of Pogostemon...???
You have caught my thought, this inflorescence is too long and also robust but sir due to the leaf character I feel hard to identify it as M longifolia.
I did'nt mean to call it M. longifolia. If it can be identified with M. longifolia, then surely it is more correctly M. asiatica, I meant inflorescence is too long and robust for both the species.
I Just told you that as u discussed the matter with me. Sorry if you have thought that I meant to say that you suggested M longifolia, you never told this name. Sorry For the misunderstanding I have created please pardon me for the innocence
Mentha asiatica as per earlier opinion.
While interacting with ..., he indicated that this could be some sp. of "Elsholtzia". I had cropped few pics. Requesting you to have a fresh look.
E. stauntonii seems to be the closest call
Well. The close look shows it might be Ocimum or Orthosiphon (the stamens are much longer)
