to Chusquea, from which, as far as the structure and details of the spicula are concerned, 

 it can scarcely be distinguished, although in inflorescence and foliage the two genera are 

 widely apart ; and I have already, at pp. 52 and 53, slated in what respects these two 

 genera differ from all other grasses.

This plant, as represented by Kunth in his fine drawing, has very much the general 

 appearance of a large Eragrostis, and is extremely like P. acumiuatissiaia, which, how- 

 ever, is well distinguished by its long glumes.
