I was consulting poaceae genera given in my ‘plant groups’ book along with the internet. Found two similar species –

This grass has been identified by … as Pennisetum purpureum Schumacher, along with a note at another thread at – efi thread

Yes, it is Pennisetum purpureum, commonly called Napier grass. 

I cannot express in writing how i am thankful to you. I have one earlier post of similar looking grass and i think that is also P. purpureumefi thread

Yes. That is also the same. However, under cultivation, there are also hybrid napiers which are man made hybrids of Pennisetum purpureum and P.americanum (Bajra). Their seeds will not be fertile.

Manoj why would they be hybridized? for what purpose?

ANd I have one more silly question…
how does our Indian Bajra become p. americanum????? american??

I found a well written paper at this site for the hybridization and its utility in animal husbandry …

When i searched the net for Pennisetum species in West Bengal i came across the cultivated hybrid of the two Pennisetum species as you have mentioned here. But, i think this grass is no more cultivated in our locality, instead i have seen cultivation of another fodder grass and i have a post of that species too, at – efi thread.

It is just a nomenclature change. Earlier, Indian and African Bajra was known as Pennisetum typhoides. There was another species called P.spicatum from Africa, which later on was found to be just a variation of Pennisetum americanum, which is based on the originally published Panicum americanum Linn. published in 1753. A detailed study of P.americanum and P.typhoides from different areas and by different authors finally led to the consensus that both of them have several variations which are continuous in nature and hence should be considered as the same species. By rule of priority of publication, Pennisetum americanum (Linn.) K.Schum. was accepted as the correct name of pearl millet (bajra).

Pennisetum polystachion (L.) Schult.  ??

No doubt it is Pennisetum genus. but species is doubtful

Looks more like an unusual variety of Napier grassPennisetum purpureum. The commonly grown varieties do not have such a hirsute leaf base.
In case of P.polystachyon, the rachis of the spike would be winged along its ribs. The inner bristles of the spikelets also would be hairy. Also, if you squeeze a spikelet from its bottom, the upper floret will jump out and fall off. You can try this trick to confirm. This feature of jumping floret is seen in P.polystachyon, P.pedicellatum and P.setosum and P.hordeoides.

Thank you …!! Nepali Name : नेपियर घाँस Nepiyar Ghaans
