22. Carex tahoensis, sp. nov. 



Khizoma caespitosum. Culmus 1.5-3 dm. altus subfirmus triqueter 

 scaber superne foliatus inferne. Folia culmo multo breviora 1 mm. 

 lata complicata rigidula pallida, vaginae inferiores hyalinae. Spiculae 

 3-4, ovatae gynaecandrae (masculina inferne), densiflorae sessiles col- 

 lectae, Squamae lanceolatae ovatae castaneosae, cum marginibus albo- 

 hyalinis, 5 mm. longae viridi-carinatae. Utriculi longiores (6 mm. 

 longi) erecti concavo-convexi brunnei nervosi, cum marginibus an- 

 gustis viridi-alatis et per dimidium superius dense ciliato-scabris, in 

 rostrum longum bidentatum sensim attenuati. Stigmata 2. 



(Plant densely caespitose. Culms 1.5-3 dm. high, rather firm and 

 somewhat triangular, roughened above, leafy at the base. Leaves light 

 green, shorter than the culm, rather rigid, 1 mm. broad and closely 

 folded along the midrib, their sheaths hyaline. Spikelets 3-4, ovate, 

 bisexual, male at base, densely flowered, sessile and approximate. 

 Scales 5 mm. long, lanceolate-ovate, castaneous, their margins broadly 

 hyaline and midnerves green. Perigynia 6 mm. long, exceeding their 

 scales, erect, concave-convex, broAvn in color and nerved on the inner 

 side above the constricted base, their narrow margins green and 

 winged, with the upper halves of the wings densely ciliate-scabrid 

 along the sides of the gradually attenuate bidentate beak. Stigmas 2. ) 



The species here proposed as new has its nearest allies in C. Lid- 

 donii Boott and C. phaeocephala Piper: from the former it differs in 

 the merely bidentate beak, which in C. Liddomi is deeply cleft and 

 in the beak being gradually acuminate, not abruptly rostrate as in 

 Dr. Boott 's species. From C. phaeocephala, this species may be dis- 

 tinguished by the much longer beak of the perigynium and the oblong 

 ovary, the latter in C. phaeocephala being obovate. 



Type collected Julj' 19, 1913, on Mt. Tallac, west of Lake Tahoe, 

 at an elevation of about 9,300 feet in the Hudsonian life-zone, Smiley
