, — a. Stem 6—8 inches (or in ^8. sometimes 2 feet) high. Leaves 

 remarkably acuminate, slightly keeled at the back, with trigonous 

 points, resembling some of the narrow-leaved species of Eriophorum. 

 Spikes almost shaggy with the long white stigmas. Scales shining-', 

 ,of a deep chocolate-brown, paler in fi. Fruit at first pale, dark brown 

 .when ripe, usually much paler In j3. As to 6., the habit is consider- 

 ably different, the fruit larger and longer, but we can find no certain 

 character by which to separate it, except that the nerves of the fruit 

 iperigijnium) are very prominent and conspicuous the whole length, 

 whereas in a. they are so obscure, particularly in the upper part, that 

 some authors describe its fruit as quite free from nerves: Dr. Boott 

 considers it identical with a vesicaria jS. alpigena Fries, but Fries 

 places it (as however he also does C. saxatilis itself) among those 

 with 3 stigmas, while we find only two. 



vi. Terminal spikelet barren, solitary {sometimes 2 in 38, 39, and 53). 

 ' Fruit glabrous (or scabrous in 53). Stigmas 3.

droopi^ig).

34. C. exterisa Gooden. (lovg-hracteated C.) ; sheaths very 

 short (scarcely any) with extremely long narrow canaliculate 

 fobaceous bracteas, fertile spikelets nearly sessile oblong, glumes 

 slightly mucronate, fruit ovate ribbed with a short straight 

 smooth acuminate beak bifid at the point, leaves very narrow 

 canaliculate, stem smooth. E. B. t. 833.
