fruit. The ligule is often shorter and usually truncate. This form 
is common in grass land in the northeastern states, where it is 
introduced or escaped from cul- 
tivation. 
Agrostis alba maritima 
(Lam.) G. F. W. Mey. Creep- 
ing bent. Differs from redtop 
in its creeping or stoloniferous 
stems and narrow panicles, the 
blades mostly short and ap- 
pressed. Native along the North 
Atlantic coast of America and 
Europe, and the Pacific coast 
from central California to British 
Columbia. The form cultivated 
for lawns appears to have been 
derived from this. 
Rhode Island bent. In 
botanical literature this name 
has been applied to Agrostis 
canina L., a grass similar in 
appearance to A. alba vulgaris, 
but usually more delicate, the 
glumes about 2 mm. long, the 
lemma about three-fourths as 
long as the glumes, bearing a 
little below the middle a bent 
exserted awn, the palea wanting. 
This is a native of Europe and 
is rare in America. There is no 
evidence that this species has 
been cultivated in Europe or 
America. The seed sold under 
the name Rhode Island bent is

reduced; spikelet, the floret raised from 
the glumes, 3. (U. S. Dept. Agr., Div.

imported from Europe, and consists for the most part of some form 
of Agrostis alba, usually of creeping bent, or the form described 
above under A. alba vulgaris.
