Mackenzie : Notes on Carex 269 



not seen, the pistillate (terminal) linear, 1.5-4 cm. l°ng, 4-8 mm. 

 wide, with an ovate short-pointed scale-like bract at base, and an 

 elongated (2—4 cm. long) bract 1—3 cm. below, its sheath some- 

 what darkened and scarcely sheathing, often with a small peduncled 

 spike in its axil ; scales oblong-ovate, glabrous, brownish-black 

 with lighter midrib and narrow hyaline margins, acute or obtuse, 

 as wide as the perigynia but shorter ; perigynia numerous, black, 

 4-4.5 mm - l° n g> 1-5 mm. wide, the body lanceolate, flattish, rounded 

 at base, tapering at apex into the minute entire (or nearly entire) 

 beak (0.5 mm. long), minutely puberulent and pubescent on the 

 angles above ; achenes triangular, 2 mm. long ; stigmas three. 



The perigynium in this plant is so nearly glabrous in age that 

 at a first glance it appears completely so, and this lack of apparent 

 pubescence gives the species a very different aspect from that of 

 C. scirpoidea.
