marginibus latemlibiis inslnicti in rostrum continiiatis, in parte dimidia superiore dense 

 aculeatis. Nux late ovata, 1,5-2 mm. longa, trigona, lateribus concavis, apice stylo 

 cylindriaco instrucla. Stigmata 3, longiora. 



In point of external habitus this species resembles not a little Carex capillaris, espe- 

 cially so the subspecies Ledebouriana C, A. Meyer = Carex lenaeensis Kukenthal, 

 Cariceae Cajanderianae (1903) p. 10, with the description of which it agrees in many 

 respects. Carex fraudiilans nov. spec, however, is distinctly divergent in its considerably 

 larger spikes, with the peduncles glabrous or slightly rough, never hairy. The bracts have 

 rather long and narrow sheaths, the lower one with a lamina levelling the middle of 

 the spike, the upper one only with a very small and much reduced lamina. The sta- 

 minate spike is large, dense and flowery, long-stalked, frequently slightly drooping, 

 distinctly much overtopping the upper pistillate spike. The glumes in the pistillate 

 spikes are of the same length as the perigynia, about 3 mm. long, gradually tapering 

 upwards, rounded or subacute at the summit, of a light yellowish brown, broadly 

 scarious-margined, and furnished with a distinct dorsal nerve, which 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 capillaris and its varieties, more or 

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

 more or less distinctly 2-cleft. The base suddenly narrowed into a rather long, cylindrical 

 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 perigynia are of about the same length as the glumes, by wMch character this 

 species is distinctly divergent from Carex koreana Komarow, which it resembles in the 

 structure of the perigynium, but in the latter species the perigynia are twice as long as 

 the glumes. The nut is about IK 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 be little doubt that this species systematically is rather nearly alhed 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 equally 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 staminate spikes, much overtopping the 

 upper pistillate spike. The stigmas are also considerably longer than in Carex capillaris. 



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

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

 July.
