Culms of medium height, very slender, 4-6 dm. high, probably pale- 
green, firm and wiry in texture, evenly and finely striate throughout, 
1-1.5 mm. in diameter at the top of the sheaths: sheaths of medium 
firmness, pale brownish-rufescent below; the uppermost greenish 
toward the summit and 9-11 em. long; involucral leaf 4-10 cm. 
long: inflorescence loosely fastigiate, 4—5.5 em. long: perianth very 
small, 2 mm. long, soft, when dry wrinkled and curved; midrib green- 
ish or tinged with pale-brown, bordered with pale-brown bands and 
narrow scarious margins: capsule scarcely equaling the perianth, pale 
olive-brown, not apiculate——CarirorNniA: Yosemite Valley, July,

This variety is usually quite distinct in appearance. It may be 
recognized by the very small pale flowers in open fastigiate inflores- 
cences, and the very slender culms with pale sheaths. 
Var. GRACILIS Hooker, Fl. Bor. Am. ii. 190, (1840).— Plant slender, 
6-8 dm. high: culms rigid and wiry, faintly many-striate throughout, 
1-1.5 mm. in diameter at the top of the sheaths: sheaths close, coria- 
ceous, lustrous, castaneous throughout; the uppermost 7-11 cm. long: 
involucral leaf 5-9 em. long: inflorescence small, varying from rather 
dense to somewhat open, 1.5-4 em. long: perianth 2-2.9 mm. long, 
soft, when dry more or less wrinkled and curved; midribs greenish, 
very slender, bordered by very broad dark-brown bands and an 
almost obsolete scarious margin; sepals very slender-pointed: cap-

A portion of the Suksdorf material was kindly compared by Dr. 
Otto Stapf with Hooker’s original specimens at Kew and he states 
that the two are undoubtedly the same.
