outer scales very obtuse, the innermost narrower and rather acute. — Arctic 

 America, and from Newfoundland and Labrador to California ; mountainous 

 parts of Europe and Northern Asia. In Nevada and Utah, from the Haval- 

 lah Mountains to the Uintas; 6,000-10,000 feet elevation. (651;) and Var. 



KOSEA, (652.) 



Antennaeia dimoepha, T. & Gr. Dwarf, csespitose ; stems i^-2' high 

 from a somewhat woody entangled caudex ; leaves 2-12" long, silvery- 

 tomentose ; the radical spatulate, their bases inclosing large ovoid-fusiform 

 white-woolly leaf-buds; stem-leaves linear, the uppermost exceeding the 

 solitary top-shaped heads ; sterile heads with ovate-lanceolate scarious brown- 

 ish involucral scales, the outer ones shorter and woolly at the base, pappus 

 strongly barbellate toward the ends ; fertile heads larger, the inner involu- 

 cral scales lanceolate-acuminate, equaling the very slender and nearly 

 smooth setas of the pappus. — Two forms occur : — 



Var. NuTTALLii. Stems 4-6" high ; leaves proportionately small ; fer- 

 tile heads 3-4" long ; styles slightly exserted. (653.) 



Var. MACEOCEPHALA. Stems 8-15" high; leaves often 1' long, very 

 silky, and the pod-like buds very large ; fertile heads 7-9" long ; styles 

 sometimes exserted, but often only half as long as the corolla. (654.) 

 Both forms occur on the foot-hills from the Sierras to the Wahsatch, at 

 4,500-6,000 feet elevation ; May, June. The smaller form was collected 

 near Virginia City by Bloomer, and in the Black Hills of the Platte by 

 Nuttall. 



Aenica longieolia. Many-stemmed from a scaly caudex, minutely 

 scabrous-puberulent ; leaves in 5-6 pairs, elongated, lanceolate, acuminate, 

 denticulate, the upper pairs sessile and slightly connate-amplexicaul, the 

 lower with sheathing connate petioles ; heads 1-8, commonly 5, not 

 large ; involucral scales lanceolate, acute ; achenia minutely glandular, but 

 not hispid. — Stems 14-24' high ; leaves 5-6' long, 7-10" broad, the very 

 lowest reduced to ocreate scales. In dense clumps among rocks. Clover 

 Mountains, Nevada, and in the Uintas above Bear River Caiion; 10,000 feet 

 altitude; August, September. (655.) 



Aenica angustifolia, Vahl. Hirsute or hairy ; leaves lanceolate, 3-5- 

 ribbed, entire or remotely denticulate, radical ones and the lowest pair taper- 

 ing into short petioles ; cauline in 1-3 pairs, sessile ; heads 1-3 ; involucre 

 villous-hirsute, [woolly, T. 4* G.-] achenia hirsute. — Arctic America and
