instead of being marginal on one side of tlie racliis, tliey are deeply 

 embedded in alternate cavities on the outer and lower side of that 

 raehis. 



Aii<i.'<froj>Jiu.<i, tlie third section, was pro])osed as a genus by 

 Sell lech tendahl. In this the s})ikelets are on alternate margins ot* 

 the narrow, somewhat tlexuose raehis of tlie spike and the back of 

 tlic floral glume being turned outwards from the raehis. The 

 spikes are generally several, close together at the end of the 

 l)ed uncle. 



Besides the above valuable notes taken from Bentham, cou- 

 sideral)le aid has been received from a valuable synopsis of the 

 genus by Vasey, in ]?ull, 'i'orr. Club, i;}: l(;-2 (1S8(1).
