No. 2786. Mountain meadows of the presidium ; Feb. 1857. No. 2783. 
A widely and closely cespitose 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 Ustilago 
Cesatit Fisch. 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. typicus and hispidissimus of Hackel (i.c., pp. 586, 587); 
but I agree with Sir J. D. Hooker (FI. Brit. Ind. vii. p. 200) that 
the character is too inconstant for such definition of subvarieties.
