 Lake to the shores of the Arctic Sea. Dr Hichardson. — Of this little known grass, Dr Richardson has the 

 following description in his notes made on the recent plant — " Calyx of 2 unequal valves, which are ovato- 

 lanceolate, boat-shaped, concave, scarcely acuminate, compressed, quite smooth and entire, reddish-brown 

 and shining ; smaller valve half the size of the other. Corolla of 2 nearly equal valves, of similar colour and 

 consistence with the calyx, equal to, or rather longer than the larger valve of the calyx ; its outer valve em- 

 bracing the inner, and a little longer : both obtuse, compressed, serrulated at the keel, otherwise smooth, 

 somewhat membranaceous at the margin and edges, and there entire. Stamens 3. Styles 2 ? perhaps united. 

 Stigmas plumose, branching ? Seed loose. This seed appears to be oblong, and there are 2 or 3 lanceo- 

 late, pointed membranaceous scales. — I should be disposed to refer it to Ciiina, if it had only one stamen 

 and one style ; as it is, it possesses all the characters of Vilfa or Colpodium."

3. C. pauciflorum ; panicula erecta spicsefornii angusta pauciflora, gluma perianthium 

 superante uniflora cum rudimento pedicellato, valvis subeequantibus acutissimis carina 

 superne prsecipue aspera unifloris, perianthioobtuso valvis apice dorso marginibusque as- 

 perulis, foliis lineari-acuminalis subrigidis siccitate complicatis vel marginibus involutis. 



Hab. Between Fort William and Cumberland House Fort. Dr Richardson. — Smaller and much slenderer 

 than C. latifolium, with a very narrow few-flowered panicle, the floret of a much paler and greener hue, the 

 glumes sharper and constantly longer than the perianth ; and there is always a distinct but abortive pedicel- 

 late floret present, arising from the base of the inner valve of the perfect one.
