Kindly mention habitat. P. setosum is usually cultivated, taller with longer and thicker spikes.


Its on the bank of a pond in kaiga & water lasts throughout the year.Sorry for the late reply.


Please also check with P. orientalis??


yes its Pennisetum orientalis, check description in cooke’s flora


The picture (grass) looks like P. purpureum – a common fodder grass often found as a feild escape. But confirmation is a must by disecting the spikelets. However, I am sure that was not P. orientalis which is usually grown as a ornamental garden grass. 


Pennisetum pedicellatum Trin.


i also go with … pennisetum pedicellatum


i still go with P. orientale and not Pennisetum purpureum which is quite tall grass


I agree with … that it can’t be P. purpureum which is a much taller grass with much broader leaves and dense inflorescence.


It is also not P. setaceum a South African grass with dense spike and stiffer short bristles, often cultivated in gardens.

Pennisetum pedicellatum and P. orientale are closely similar but the spikelets in P. orientale are much separated, rachis hairy and bristles much longer and plumose.
I am also attaching my photograph of P. orientale from Kashmir and P. setaceum from California for comparison
The more denser arrangement of spikelets and shorter bristles suggests P. pedicellatum for above plant as indicated by Nirbay ji and Anil ji, out expert on grasses.
You may please compare above and give your opinion


sirji your photo of P. orientale look quite different,, very interesting


I feel this is pennisetum pedicellatum
