COMPOSITE. 31 



On dry stony ground in the lowlands about Gunnison, 

 nn. 449 and 840. 



ARTEMISIA BAKERI. Allied to A. Mexicana but more 

 slender, and with the tufted stems decumbent or depressed 

 and also rather loosely branching: foliage rather sparse, 

 green and glabrous above, white-torn entose beneath, the 

 lower leaves with few and rather remote pinnate segments, 

 those of the branchlets entire, all linear or with linear seg- 

 ments, the margins narrowly re volute: heads in an ample 

 and loose panicle, many of them short-pedicellate, campanu- 

 late, the outer bracts short, herbaceous, acute, the inner 

 obtuse and largely scarious, all somewhat arachnoid- 

 canescent. 



This species, very well marked as to habit, was first col- 

 lected by myself, in the canon of the Gunnison, near 

 Cimarron, Colorado, in August of 1896. Mr. Baker now 

 distributes it, and from the original station, or near it, 

 under n. 698. 



ERIGERON SIMULANS. Near E. pumilus and of the same 

 size and habit, the many short stems crowning the taproot 

 almost or altogether herbaceous; the spatulate-linear leaves 

 strongly and very stiffly hispid-ciliate from the base to the 

 middle, the upper portion (or proper blade) with a finer 

 strigose hairiness closely appressed: pedunculiform mono- 

 cephalous branches sparingly leafy below, slender and 

 naked under the involucre, this green and as if glabrous 

 to the unaided eye, but its outermost bracts sparsely bristly- 

 hairy: rays pale flesh-color or white: outer pappus very 

 conspicuous, of oblong-obovate acutish laciniate-toothed 

 paleae.
