 A widely and closely ca3spitose grass, very rarely well-developed on 

 account of the plentiful disease of the spikelets. In thicket-grown 

 meadows near Pedras de Guinga ; March 1857. No. 2806. 



These last two numbers have the spikes much eaten and dis- 

 torted by a fungus, which Miss Smith has determined as UstUago 

 •Cesatii Fiseh. de Waldh. 



The numbers included show considerable variation in the hairi- 

 ness of the outer- glume of the male spikelet, and would fall under 

 subvars. ti/jncns and Mspidisshaus of Hackel {I.e., pp. 586, 587): 

 but I agree with Sir J. D. Hooker (Fl. Brit. Ind. vii. p. 200) that 

 the character is too inconstant for such definition of subvarieties.
