ENGLISH BOTANl'. 
Generally distributed in England ; more rare in Scotland, extending 
north to Aberdeen and Stirling. Not common in Ireland, and there 
found chiefly in the south and middle of the island. 
England, Scotland, Ireland. Perennial. Summer. 
Rootstock shortly creeping, producing at its apex a small dense 
tuft consisting of stems and barren shoots, and producing rather short 
slender subterranean stolons, which in the succeeding year produce 
tufts similar to those of the parent, from which they become discon- 
nected. Stems 9 inches to 2 feet high. Longest leaves 2 to 4 inches 
long by J to \ inch broad, gradually tapering. Panicle 2 to 6 inches 
long, Spikelets i to i inch long, exclusive of the awns. 
On the Continent a variety of this plant occurs, with the spikelets 
variegated with violet, but I have seen no British specimens of this 
form.
