A much smaller plant than Æ. comosum, of which it has been regarded as а 
depauperated alpine form. The inflorescence, however, is very different, and the leaves 
and bracts are relatively very much shorter, Figures Bl and B2, representing a 
spikelet and a flower of E. comosum, mdicate other important differences, such as the 
shape of the glumes, the length of the bristle, and the very different shape of the 
nut. |
