long as the glumes and of the same texture, lower pale with a 
bent awn from its lower part, which exceeds the glumes. Hairs 
very short, about 4/1 of the length of the pale; the rudiment of 
the second flower with longer hairs, about half as long as the pale. 
The Arctic form (C. purpurascens R. Br.) has lower culms, 20— 
50 cm. high, and a spike-like contracted, 5—8 cm. long panicle, 
tinged with purple or violet.

Obs. We have seen the specimens in the Herb. of the Riksmuseum at Stock-

they are C. arundinacea, f. purpurascens.

Loosely czespitose. Culm with about 3 joints, of which the 
uppermost occupies more than half of the length of the culm, 
somewhat scabrous in the upper part. Leaves with prominent 
scabrous veins on the upper surface, sometimes slightly involute; 
ligule short, obtuse, sheaths slightly scabrous. Panicle narrow, ob- 
tuse, generally tinged with violet. Glumes ovate-lanceolate, acute, 
about 5 mm. long, scabrous on the dorsal vein. Pales unequal, 
lower pale slightly shorter than the glumes and with a stout, bent 
or straight awn from below the middle. Hairs as long as the pale 
or somewhat shorter; rudiment short and with long hairs. 
The Arctic form (C. hyperborea Lge.) has short, straight awns, 
and the hairs are not so long as the pale, also the panicle is more 
contracted.
