Neyraudia reynaudiana from Arunachal Pradesh_RKC: 5 posts by 4 authors. Attachments (5).
Neyraudia reynaudiana (Kunth) Keng ex Hitchc.
Loc.: Itanagar, Arunachal Pradesh, ca 550 m.
Date: 2006 (can’t remember the month).

– Thanks For sharing the photos of Burma grass 

I think this species need to be worked out again as it is definitely not Neyraudia, which is a reed like grass. N.arundinacea is common in Himalayan foothills whereas N.reynaudiana is common in north-east india and burma, which is also a tall reed.
I think this species need to be worked out again as it is definitely not Neyraudia, which is a reed like grass. N.arundinacea is common in Himalayan foothills whereas N.reynaudiana is common in north-east india and burma, which is also a tall reed. The tapering leafbase in this picture clearly indicates its affinity towards Microstegium, but the branched panicle puts it towards Spodiopogon. The general habit and habitat as seen from the pictures is of the various Microstegium species found all over the slopes of north-east India, but usually they have digitate or subdigitate racemes. It is also to be noted that both the genera have several morphological characters in common.

It would be nice if very close up photographs of the inflorescence is posted. Also kindly mention whether the lower glume is channelled/furrowed on the back (a character of Microstegium).
A sample photograph of Burma reed grass can be seen at this link

This is Thysanolaena latifolia

Not Thysanolaena. Kindly observe the slender awns on the spikelets. Thysanolaena are completely awnless. Also Thysanolaena have large leaves and are not narrowed to a petiole at the base. Of course, it is found in similar habitat.

Thanks … for responding to this thread. But to me it does not look like a Thaysanolaena. Thanks to … and … too for the efforts.
I am forwarding this to …, BSI, Itanagar who is expert on monocots of North East. Hoping a kind response.

The specimen may be belongs to Hemisorghum sp. and closely resembles to Lakshmia Veldk.(?) Need for microscopic observation

It is Microstegium petiolare
