Cyperus alulatus J.Kern, Reinwardtia 1: 463 1952.;
Both looks very similar. Identity can be confirmed by checking the specimens.
Rachis of spikes glabrous and keel of the glumes smooth (not spinulose ciliate) ………….. C. iria
Rachis of spikes hispid on angles and keel of the glumes spinulose ciliate ………………….. C. alulatus
Spikes finally reflexed; glumes 1.5-2 mm….. Cyperus alulatus
Spikes suberect; glumes 1-1.5 mm…………. Cyperus iria
Cook (1996) reported the species as endemic to India, Nepal and Pakistan. He reported the distribution in Andhra Pradesh, Himachal Pradesh, Gujarat, Jammu and Kashmir, Karnataka, Maharashtra, Orissa, Punjab and Rajasthan. It is common in all districts in Maharashtra (Lakshminarasimhan 1996).

It can be either Cyperus iria or C. alulatus, both are very similar. In Cyperus iria rachis of the spikes are glabrous and glumes not spinulose-ciliate on the keel But in C. alulatus rachis of the spikes are hispid on angles and glumes are often spinulose-ciliate on the keel.
Yes Cyprus alulatus..
Please identify this grass.
I Hope Cyperus alulatus C. iria ? It can be either Cyperus iria or C. alulatus. The inflorescence need to be examined with a lens or under a microscope to confirm the identity. Cyperus alulatus
Need help to identify this Cyperaceae

Cyperus alulatus I found the keys as below: Spikes finally reflexed; glumes 1.5-2 mm….. Cyperus alulatus
Spikes suberect; glumes 1-1.5 mm…………. Cyperus iria
Cyperus iria spikelets hang loose, in C. alulatus they are always stiff, perpendicular to the axis/ rachis …both pretty common in Surat. C. alulatus can be seen 15 cm to 100 cm tall bearing spikes, in C. iria I am yet to see a less than 30 cm plant with spike.
