Closely allied to the northern A. canina Linn., to which it was originally referred 
by Sir J. D. Hooker. But it differs from all the forms of A. canina, as has been pointed 
out by Professor Hackel, in the innovation-shoots being always intravaginal, in the 
more scabrid leaves, in the narrower and more contracted panicles, and in the rather 
larger spikelets. It usually constitutes a large proportion of the alpine pastures in 
elevated districts in both Islands. 4p — (Vit —43

capillary, scaberulous, again branched ; pedicels hardly thickened at the

4 in. long, pale-green. Two outer glumes equal, lanceolate, acute, I-nerved,

Tans ss: 319 _ According to Professor Hackel this is nearest to A. canina, which differs in its 
bright-green smooth leaves, much more compound and closer panicle, smaller spikelets, 
in the scabrid keel of the empty glumes, and small anthers. A. Dyeri is separated by 
the innovation-shoots being intravaginal and not clothed with leafless scales, to say 
nothing of the broader leaves, dense panicle, and spikelets with the empty glumes 
scabrid on the keel. ¥ (94-3— Fo, —
