former species a central, sometimes winged, line goes from the convex 

 surface of tlie fruit along the beak, giving it a triangular form. (Boott.) 

 The C. paradoxa of continental writers appears to be almost interme- 

 diate between them.

 — Root creeping. Stem 1 — 2 ft. high, erect, acutely triangular, rough, 

 leafy at the base, and clothed with purple sheaths which are torn and 

 reticulated at their edges. Leaves straight, shorter than the stem. Middle 

 spikes smallest, more or less approximate. Bracteas rough, auricled, 

 but without sheaths, the lowest sometimes longer than the stem ; upper 

 ones setaceous. Fruit glaucous-green, stained with brown, shorter at the 

 base of the spikelets than the cuspidate scales, which are brown with a 

 pale green nerve. — Linnaeus confounded C alpina, Vahl ( C. Vahlii, 

 Sclikh.) and C. curta, Good, with this species. The specimens from 

 Lapland are of the present plant. C. curta was described by the late 

 Bishop of Carlisle in the Linn. Trans, v. 2. p. 145, in 1792, eleven years 

 before Wahlenberg, in Act. Holm. (1803) described the present species 

 under the name of C. Bux baumii. The original name of C. canescens 

 must be restored to it. (Boott.)
