Revisiting upload of Cotula anthemoides from Kashmir: It is Matricaria matricaroides:
I had uploaded a weed from Kashmir identified as Cotula anthemoides, and incidentally it also appears on Flowers of India
While visiting Kashmir again I found another plant similar to this one, and on thorough scrutiny discovered that my above plant is not Cotula anthemoides, which has lighter coloured heads and broader and shorter leaf segments. My plant is in fact Matricaria matricarioides or pineapple weed. Please go through the following link: http://www.ppws.vt.edu/scott/weed_id/matmt.htm
Here are some details about the plant:
Matricaria matricarioides (Less.) Porter ex Britton, Mem. Torrey Bot. Club. 5: 341. 1894.
syn: Artemisia matricarioides Less., Linnaea 6: 210. 1831; Matricaria discoidea DC.
Common names: Pineapple weed, false chamomile, rayless chamomile
Erect or ascending annual herb emitting pineapple like smell when leaves are crushed; leaves alternate up to 5 cm long, 2-pinnatisect with linear up to 2 mm wide ultimate segments; heads discoid, 7-12 mm across, conical, greenish yellow; involucre bracts oblong with broad hyaline margin and obtuse apex; florets tubular, 5-lobed; achene with a white corona.
Common in Kashmir along roadsides and wastelands, leaves resembling Anthemis cotula. Photographed from Srinagar Kashmir. I am again uploading the plant with correction.
The other species Matricaria area I am uploading separately.

Cotula anthemoides from Kashmir: Cotula anthemoides from Kashmir, growing along roadsides and waste places. The leaves resemble Anthemis, but the heads are different.

Plant ID Kashmir:  Plz validate the ID of Matricaria matricarioides (Less.) Porter (Syn:Matricaria discoidea DC.)
Growing on dry sites in Kashmir
Yes dear ... Matricaria matricarioides
Please also keep track of another: Matricaria aurea (earlier known as Cotula aurea), which was once more common in Kashmir, smaller plant, smaller more yellowish heads, involucre bracts with brownish (not white) margin, 4-lobed (and not 5-lobed) corolla and smaller leaf segments. You will find both growing side by side in Gurdwara Chhatipadshahi parking in the month of May.
Here are mine from Kashmir
In future uploads please first reduce picture size to 800 x 600 approx before uploading.

There was no problem till Matricaria matricarioides  (Less.) Porter ex Britton and Matricaria discoidea DC. were considered as synonyms, but now it seems two are treated distinct by both GRIN and The Plant List. It would thus worthwhile to find out differences between two taxa, so that we can place our specimens precisely. May be any researcher will help.

Another member of Asteraceae which I captured nearby a lake from our community.
Matricaria discoidea DC. (Pineapple weed)
Date: June, 2013
Place: Fountain Square, Illinois, US
Annual , 3-12" tall, branching frequently and having the appearance of a miniature bush. Fern-like leaves, alternate along the glabrous stems. Leaves pinnately divided into linear lobes. Flowerhead of each stalk is about 1/3" across, and consists of numerous greenish yellow disk florets and no ray florets. Both the foliage and flowerheads have a pineapple-like odor when they are bruised or crushed.
The blooming period occurs during the summer and lasts about 1-2 months. Each disk floret is replaced by an oblong achene that is broader at the top than the bottom.
