... flowers of grass :: 29AUG09

[Dinesh Valke]

Hello friends,

 

I see this grass now flowering commonly in and around Thane (perhaps common in many places in India).

ID please.

 

(I did not think of leaves and other aspects of this grass)

 

Regards.

Saccharum spontaneum?

Not Saccharum spontaneum Rakesh ji. Here are pictures of Saccharum spontaneum.

Hi Dinesh,

I guess it to be Chloris sp. (C. barbata??)

Thank you very much, Gurcharan ji and Swapna,

 

I searched Flickr:

1) http://www.flickr.com/search/?s=int&w=all&q=Chloris+barbata&m=text

2) http://www.flickr.com/search/?s=int&w=all&q=Eleusine&m=text

 

... I find Chloris barbata convincing at present.

Satish ji, do you not think it to be Chloris barbata, as already put by Swapna, Rani ji and Prashant ?

 

At http://members.iinet.net.au/~weeds/western_weeds/poaceae_three.htm ...Chloris (windmill grasses) have an inflorescence that is usually purplish and composed of numerous digitate spikelets arranged on a short axis ... C. barbata (purpletop chloris) is an annual or short-lived perennial, to 90cm tall. It is distinguished by having three awns per spikelet (as opposed to two in other Chloris species) ...

 

The purplish colour of inflorescence is stressed in most of the descriptions, like http://plantsforuse.com/index.php?page=1&id=2117 and through http://www.efloras.org/browse.aspx?flora_id=5&start_taxon_id=106781

 

Attaching inflorescence (large size), but I wonder whether it would be of any help in counting "the three awns per spikelet".

 

Regards.

Satish ji's response below ....

Many thanks satish ji for the clarity and ID.

 

Regards.

Purplish inflorescneecis common in all the species of Chloris genus.
the pointis if the awns are 3 per spikelet then it is C. barbarata.
i guessed it C. virgata because of the short length of the spikes.
(c.barbarata has much longer spikes).

and

take a look at the size of the spikes  (inflorescence)
