The flowering annual herb Leucas cephalotes is a common weed which also has uses as an edible vegetable and herbal remedy. It has many common names, including guma, dronpushpi or drona puspi, and tou xu bai rong cao. It is a common plant across Asia from China to the Indian subcontinent.
L. cephalotes springs up in cultivated fields as a weed, especially after a period of rain. It is collected for use as a leafy vegetable in rural areas. It is cultivated itself for its medicinal uses and is readily available in markets. One of the plant's most common historical uses has been as a treatment for snakebite. It is also steeped in water which is then used for bathing and for washing livestock.

After photographing this plant from fields outside Jim corbett and identifying it as Leucas cephalotes (Roth) Spreng., I noticed that the species although very distinctive is not represented on Flowers of India. Next I checked our database and realised that though several uploads have been suggested as L. cephalotes, they mostly turned out to be some other species.
The species is very distinct from other species that it has single terminal compact head-like verticillaster with numerous closely overlapping bracts which concoel most of the calyx, and only one or two flowers may be seen coming out at a time, one or two floral leaves emerging from top of the head. The leaves are ovate to lanceolate in shape. Plant is up to 1 m tall with hispid stems.
Thanks Sir for this upload, I thought this is a common plant, strange to know that this is not represented on the forum. ...I will share my pics of the same from Panipat and Morni Hills. ....anyway, thanks a lot for your upload from the latest tour....hope to see many more......
A few uploads earlier identified as Leucas cephalotes:
Leucas (from ...)
Pl. correct if any of the above post is wrongly identified.
One uploaded by ... is clearly not L. cephalotes. It appears L. aspera
One by ... may be but bracts are not clear from distant shot

Leucas aspera I hope.
Leucas aspera (Willd.) Link should have (ref. FoC) -
  • densely hispid many flowered globose verticillaster
  • hispid linear bracts as long as calyx
  • oblique calyx mouth, calyx hispid outside, teeth straight-triangular-spinescent apex
This species is not Leucas aspera (Willd.) Link. This species is L. cephalotes (Roth.) Sprengel.

This species is not Leucas aspera (Willd.) Link.

This is recorded from Panipat..
I hope this is Leucas cephalotes, please validate/correct..

The plant in the attached photo is ..............
Leucas cephalotes (Roth) Sprengel, Syst. Veg. 2: 743. 1825.
[Syn: Phlomis cephalotes Roth, Nov. Pl. Sp. 262. 1821; Leucas capitata Desfontaines.]
Herbs annual, to 90 cm tall. Stems hispid. Leaf blade ovate to lanceolate, 5-10 cm, membranous, pubescent, base cuneate, margin crenate-serrate, apex acute. Verticillasters terminal, globose, many flowered, to 5 cm in diam.; bracts narrow lanceolate, overlapping, concealing calyces. Calyx tubular, ca. 2 cm, slightly curved, softly pubescent; teeth very short, subulate.
"I think ... is right
it looks like Leucas cephalotes from lamiaceae
Could it be a dried up plant of Leucas Indica?
Please check the link http://www.flickr.com/photos/amithes/3386432033/

I think inflorescence and leaf morphology does not match with Leuca indica
