Hhynchelytrum grandlflorum, Hoclist. (in 'Flora,' 1844, 249) is very 

 near to our plant, and 'perhaps might have been rightly reduced as 

 synonymous, but in view of the much larger spikelets I have hesitated 

 to cite it formally as such. Both Rhynchehjtrum and Monachyron 

 were reduced to rric/io/fraT. by Hackel (Engl, and Prantl, 'POanzen- 

 familien,' ii. Gram. 36), and Dr. Baillon has also pointed out their 

 identity in 'Bull. Soc. Linn. Par.' They are all three reduced by hmi 

 to Panicum (' Hist, des Plantes,' xli. [Gram. ] 175). In ' Genera Flant- 

 arum ' they are referred to three different tribes ; Moyuichyron at the 

 tune it was worked up, not being represented in the Kew Herbarium. 

 Tricholffna Wiyldii is another near ally of our plant, with larger ana 



moie villous glumes.— D. Oliver.
