ARTHRAXON NUDUM, Benth. 
Caules vagi, e nodis radicosi. Folia 2-24 uncias longa, oblonga, 
cordata, basi in marginibus ciliata. Corymbi abbreviati (specie 
subumbelliformes), glabri; ramuli 10-15 tenues, simpliciter spi- 
cati. Spicule virides; glume superne spinoso-scabrw ; arist® 
pars exserta eum spicula xquilonga—Batratherum nudum, Nees

Kohima, alt. 3000 feet. 
An abundant grass throughout the eastern frontier of Bengal ; 
well represented in the collection of Hook. f. et T. Thoms. in the 
Kew Herbarium, and from the way in which it is written up 
* Batratherum nudum, Nees,” I infer that Nees has published 
that name somewhere, but I cannot find where. As to Pollinia 
nuda, Steud., Steudel himself states that it is equal to Leptatherum 
Royleanum, Nees, and from the description that appears so to be; 
nor is it any objection to this reduction that Steudel himself on 
the preceding page has admitted Leptatherum Royleanum, Nees, 
as a good species, the type of a distinct genus.
