Leptochloa panicea is distributed in Africa, Asia-temperate, Asia-tropical, Australasia and America. In India it is distributed in Madhya Pradesh (Damoh) (Roy 2001), Andhra Pradesh (Anakapalli) (Rao and Kumari 2008), Tamil Nadu (Kabeer and Nair 2009) and Maharashtra (Amaravati, Aurangabad, Bombay, Nagpur) (Lakshminrrasimhan 1996, Rao and Kumari 2008).
Leptochloa panicea is an annual slender grass found in damp or periodically flooded places but not wetland species (Cook 1996) and also grows in riverbanks, lake margins, sloughs, bottomland forest openings, ditches, roadsides and railroads (www.missouriplants.com). It is a weed of rice, corn, cotton, soybeans, sugarcane, peanuts and pastures (Waterhouse and Mitchell 1998).

Dinebra panicea (Retz.) P M Peterson (syn: Leptochloa panicea Retz.) photographed from Delhi, pl validate

It is Leptochloa panicea. But the genus Dinebra does not fit for the nomenclature as Dinebra is far too different.

Here are in support of my conclusion for Dinebra

The combination has been published in 2012, and verified by GRIN in 2013.
In any case two are synonyms.

If this is a Leptochloa species, with its flexuose racemes it should be L. chinensis (L.) Nees.
I found this grass today in a dry canal. I do not have any detail because it was not possible to go near it.
I have another similar looking, pending since last year – efi thread

Yes. Leptochloa sp. Number of florets per spikelet need to be seen for species identification. For that, photo of fresh specimen would be required.

Only possibilities are L.chinensis and L.panicea

Thank you very much Sir. I understand that close-up photo is needed to determine it to the species level. Next time i will record the same if i can get close to similar looking grasses.
