E. bellioides it might be supposed to be a variety of that species, but 

 no intermediate forms are detected among previous collections. 



AsTEii FouAVOODii. Of the A. puuiceus group, stout and leafy 

 (2 feet high), rough-pubescent: leaves large (4 inches long), sessile, 

 ovate to lanceolate, short-acuminate, narrowed to a broad subauricu- 

 late base, coarsely serrate, very scabrous, hairy on the veins beneath ; 

 bracts of the corymbose panicle small and narrow : heads large (6 

 lines high) ; scales rigid, very unequal, short-acuminate with lax or 

 squarrose herbaceous tips : rays purple, 4 to 6 lines long. — Black 

 Hills of S. Dakota; Dr. W. H. Forwood, U. S. A., August, 1887. 

 A strongly marked species, clearly distinct from A. pum'ceus and 

 A. Cusickii, and in habit much resembling A. foliaceus, var. Caiihrji. 



Artemisia Forwoodii. Biennial, erect, 2 feet high, the simple 

 stem bearing numerous axillary erect narrow and slender panicles : 

 leaves canescent both sides with a short villous pubescence or the 

 upper glabrous above, twice pinnately parted into linear acute seg- 

 ments ; bracts of the glabrous intlorescence small, linear, entire : 

 heads numerous, small (1 to 1^- lines broad), globose-campanulate, 

 with thin and subscarious greenish scales, 15-20-flowered. — Black 

 Hills of S. Dakota ; Dr. W. H. Forwood, September, 1887. Re- 

 sembling A. discolor, with very numerous smaller subglobose heads in 

 an elongated narrow compound panicle. 



LEriDosPARTUJi LATisQUAMUM. A compact shrub 3 to 5 feet 

 high, with numerous erect branches, floccose-tomentose and angled 

 with mostly continuous lines of prominent greenish glands : leaves 

 filiform, acute, an inch long or less : heads clustered at the ends of 

 the branches, about 5-flowered ; involucral scales broad and ap- 

 pressed, ovate to oblong, very obtuse, rigid and scariously margined, 

 tomentose : corolla very deeply cleft : achenes densely villous, the 

 long silky hairs passing into the very copious pappus. — Soda Spring 

 Canon, Esmeralda County, Nevada, at 6,000 feet altitude ; W. H. 

 Shockley, August, 1888. The anthers are almost caudate at base, 

 but for which character the genus might be considered most nearly 

 allied to Bigelovia. 



HiERAciUM (Stenotheca) nigrocollinum. Subscapose, a foot 

 high, sparsely hirsute throughout with white hairs: radical leaves 

 thin, oblong-spatulate, obtuse, entire, the one or two on the base of 

 the stem oblanceolate and acute : heads rather few in a loose oblong 

 raceme, on slender peduncles \ to 1 inch long, somewhat rufous- 

 tomentose and hispid, ^ inch long: flowers numerous and apparently 

 white: achenes (immature) somewhat tapering upward and shorter
