Carex nardina Fries. This plant is very common on all the alpine peaks 

 and rocky meadows of the Sperry Glacier region, and in Lambert Valley 

 in the Mission Mts. Though it agrees with other material from the Cas- 

 cades sent out by the Gray Herbarium, it does not accord with the usual 

 character given this species. In case it should prove distinct it may bear the 

 name Carex Stantonensis. Densely caespitose, with many large and brown 

 she'aths like C. filifolia, and with thick crowns. Root leaves many, filiform, 

 channeled, smooth, truncate, rigid, erect, .5 mm. wide, about 4 inches 

 long and as long as the stems which are filiform. Spike single, inclined to 

 be clavate and narrowed below, but acute at tip. The two lowest peri- 

 gynia contiguous, the rest imbricated closely. Spike staminate at tip and 

 with few stamens, 13 mm. long, 5 mm. wide. Bracts none. Scales 

 ovate-oval, acute, fully 2 mm. long, chestnut-colored but with lighter 

 midrib, closely investing the perygynia and fully as wide, very thin, with 

 entire edge. Perigynia closely appressed but with tip inclined to turn out, 

 manifestly inflated and with papery covering, about a third longer than the 

 akene and inclined to wrinkle lengthwise as if nerved, tip a little oblique, 

 with very short otblique beak, not cleft down the outside to speak of and 

 nearly entire. Perigynia white except the chestnut-colored tip, about as 

 long as the inflated scale, smooth except the scabrous edges above and near 

 the tip on the back, apparently plano-convex, not winged, oblong-ovate. This 

 is manifestly a close ally to C. Lyoni but differs in the much broader 

 scale, while the perigynia are 'wanting in the mature state. It is also near 

 to C. rupestris but the stigmas are two and not three and the perigynia 

 are not smooth above as in that species. Collected by Williams on a moun- 

 tain above Stanton Lake, Aug., 1894 and distributed as C. Pyrenaica.
