grass-like, those above aristate and sharply scabrid, the uppermost 
scarious and inconspicuous; basals heaths nodulose, and the mar- 
gins mostly fibrillose-reticulate.

8. Carex laciniata, Boott, Ill. 4:175, t.594. W. Boott in 
Wats, Bot. Cal. 2:243. Bailey, Proc. Am. Acad. 22:83. 
Stoloniferous; culms stout, acutely angled, seabrid, 3-10 am. 
tall; leaves glaucous, stiff, carinate, equalling the culms; lowest 
bract equalling or exceeding the inflorescence; staminate spike 
3-0 em. long, usually with 1-2 short, sessile spikes at or near 
the base; pistillate spikes 3-4, sessile, or the lowest on a long 
pedunele, 3-10 em. long; scales hardly equalling the perigynia, 
brown, narrow, the apex acute or prolonged, acicular-toothed ; 
perigynia ferrugineous, orbicular to obovoid, nerved on the 
outer face, the beak, and usually the upper margin, acicular- 
toothed, contracted at base, 3 mm. long; achenes palid, orbic- 
ular, obtuse, papillose.

The basal sheaths are described as fibrillose-margined, but 
the character does not appear in any of the numerous spect- 
mens examined.

Stoloniferous; culms erect, rough on the acute edges, 3-5 
dm. tall; leaves flat, 4-5 mm. wide, shorter than the culms; 
staminate spikes 1-3, contiguous, the lower sessile; pistiilate 
spikes 2-3, on short peduneles, 2-3 em. long, 5 mm. thick; scales 
shorter than the perigynia, lanceolate, acute or mucronulate; 
perigynia ovoid or obovoid, nerved; achenes ovoid. 
Bear Valley, 7,000 ft. alt., in the San Bernardino Mts.; 1578,

mountains, probably belong here.
