Lemma awnless or, in a few of the spikelets, with a very short awn. 
This variety has so far not been found in Canada, but may occur in 
Prince Edward Island. It has been collected at Glenwood, valley of 
Gander river, Nfld., July 11-13, 1911 (M. L. Fernald and K. M. Wiegand). 
A. canina L. x tenuis Sibth. 
This hybrid has a compartively short, 1-2 mm. long, ligule which 
clearly indicates the influence of A. tenuis Sibth. The lemma is awned as 
in A. canina L ., and the palea about one-third to almost one-half the 
length of the lemma. At least 80 per cent of the pollen grains are incapable 
of effecting fertilization. Rare.
