 respects. Care.r frdiiilidans nay. spec, iiowcvci-. is dislinclly flivcrgent in its consideiahly 

 larger spikes, with Ihc pi'(hiiu'les glabrous or slightly lough, never hairy. Tlic iiiacls have 

 ralhcr long and narrow slicallis, llic lower one wilii a lamina levelling tile middle of 

 the spike, llie upjicr one only with a very small and nnicii reduced lamina. The sta- 

 minate spike is larj^e, dense and flowery, iong-slalked. fre(]ucnllv slightly drooping, 

 distinctly much overtoj)ping the upper pistiUale sj)ike. Tiic glumes in the pistillate 

 .spikes are of the same ienglh as the perigynia, about :5 mm. long, gradually tapering 

 upwards, rounded or subacute at the sunnnit. of a light yellowish i)rown, broadly 

 scarious-margined, and furnished wilii a distinct dorsal nerve, wliicli is frequently rough. 

 They are persistent, not deciduous. In other respects, the species is characterized by 

 having the perigynia of a light yellow, the beaks of which are very long, about equally 

 narrow throughout their length, and — not as in Carex capillnris and its varieties, more or 

 less conical — distinctly apart from the perigynium itself, the orifice of which is hyaline, 

 more or less distinctlv 2-cleft. The base suddenlv narrow ed into a rather long, cvlindrical 

 stalk. The perigynium is distinctly triquetrous, with concave sides, somewhat compres- 

 sed, and furnished with 2 longitudinal lateral ribs, continued right out into the beak, and 

 distinctly beset with rather long, dense, vigorous prickles, spreading, or more or less 

 appressed. As for the rest, glabrous and nerveless. 



The perig\nia are of about the same length as the glumes, by which character this 

 species is distinctly divergent from Carex koreana Komakow. which it resembles in the 

 structure of the perigynium, l)ut in the latter species the perignnia are twice as long as 

 the glumes. The nut is about I'j to 2 mm. long, broadly ovate, triquetrous, with con- 

 cave sides, furnished above with a subcylindrical beak, truncate at the summit, and 

 filhng up the whole of the perigynium. The stigmas are 3, rather long. 



There can he little doul>l that this species systematically is rather nearly allied to 

 Carex capillaris and must be reckoned in the same section, but differs from the latter in 

 its long beak, distinctly apart from the perigynium, and etiually broad throughout its 

 length, 2-cleft at the summit, moreover in the two lateral ribs, beset with dense and long 

 prickles, and in its narrowed, frequently subacute glumes, of the same length as the 

 perigynium; moreover, in its long-stalked staminale spikes, nuicli overtopping the 

 upper pistillate spike. The stigmas are also considerably longer than in Cari-x capilldiis. 



Collected in the Altaian, at an altitude of about 2000 m. above sea-level, in some- 

 what moist, grass-grown ])laces. In flower and with ripe fruits in the second half of 

 .lulv.
