168 ENGLISH BOTANY. 
Newbould tells me he believes it is abundant in Essex, and probably 
occurs in Herts. I have a specimen from Alloa, Clackmannanshire, 
collected by Dr. Carrington. In the " Cybele Hibernica," it is said to 
be not unfrequent in Ireland. 
England, Scotland, Ireland. Biennial. Summer. 
Stems 18 inches to 8 feet high, erect. Leaves 2 to 6 inches long, 
and about I inch broad. Panicle 2 to 6 inches long. Spikelets ^ to 
I inch long, green, always glabrous. Florets | inch long, exclusive 
of the awns. Awns long, purple. 
A much slenderer and often a taller plant than B. secalinus, with 
smaller and more acute fructing spikelets. Florets not separated in 
fruit, and the margins of the pale not rolled inwards in fruit. 
The greater part of what has been called B. racemosus in Britain is 
doubtless a small state of B. commutatus, while in some cases the 
name has been applied to a glabrous state of B. mollis, but besides 
these, we have in Britain the plant named B. racemosus on the Conti- 
Racemose Brome- Grass.

Panicle (lroo[)ing. except in starved specimens, when it is sometimes 
erect. Lower panicle-])r:uiches frequently with 2 or more spike- 
lets. Spikelets oblor.g-lanceolate, always very acute. Lower pale 
not unifornily curved on the margins from the base to the apex, 
but with an obtuse an-jle a little beyond the middle on each side. 
By roadsides and in dry pa>tures and cultivated ground. ^ Piather 
land, extending north to iMoray and Aig\le. Said to be rare in 
Ireland, but with the tolKnviug qualilication by Dr. 1). Moore :—
