Carex parryana Dewey ssp. idahoa (Bailey) Murray 



Idaho sedge 



DESCRIPTION: Idaho sedge forms small clumps that arise from 

 short rhizomes. The stems are 20-35 cm (8-14 in) high with most 

 leaves crowded near the base. Leaves are flat and 2-4 mm wide. 

 Flowers are clustered in 3 (usually) oblong-cylindrical spikes, 

 1-3 cm (0.5-1 in) long, with the uppermost larger than the 

 others. Male flowers are absent or scattered among the female 

 flowers (perigynia) on the largest spike. Spikes form a narrow, 

 interrupted head, subtended by small leaf-like bracts, at the top 

 of the stems. The narrowly oval scales subtending each perigynia 

 taper to the tip and are 2-3 times longer than the perigynia. 

 These scales are brown with membranous margins and a distinct 

 pale center. Glabrous, egg-shaped perigynia are yellow-green and 

 ca. 3 mm long with a short beak. There are 3 stigmas and the 

 seed is 3-sided.
