132 COMPOSITE. Aplopappus. 



A. Brandegei. A span high from a tufted caudex, cinereous-pubescent or puberulent, and 

 the involucre lanuginous-tomentose : radical leaves obovate or spatulate or roundish (half- 

 inch long), contracted into a slender petiole; cauline few and sparse, small (quarter-inch 

 long), oblong or lanceolate : head one-third inch high and broad : bracts of involucre loose, 

 lanceolate, nearly equal : young akeues hirsute-pubescent : pappus rather scanty : style- 

 appendages triangular-subulate. Mountains of Washington Terr., in the Yakima district,

 acute. 



H H Depressed-cespitose from a multicipital lignescent caudex, glabrous or puberulent-sca- 

 brous: leaves rigid and persistent, crowded on the crowns of the caudex or on short shoots, and 

 a few on the lower part of the scapifonn flowering stems: rays 6 to 15, rather broad: style- 

 apjiendayes subulate: akenes canesceutly villous. Stenolus, Nutt. 



A . acaulis, Gn.vv. Leaves from spatulate (and inch or less long) to oblanceolate or linear

 bracts of the involucre from ovate to ovate-lanceolate, mucronately acute or acuminate, desti- 

 tute of greenish tips; the outer a little shorter than the inner. Proc. Am. Acad. vii. 353;

A. armerioid.es, GRAY. Smooth and glabrous : flowering stems naked above (for 1 to 3 

 inches), sometimes nearly scapiform : bracts of the campanulate involucre broadly oval,

 most of them greenish at apex. Stenotus armerioides, Nutt. 1. c. ; Torr. & Gray, 1. c.

 Too near the preceding. 



A. stenophyllus, GIIAY. More snffruticulose, hirtellous-scabrous : leaves very narrow, 

 linear-spat nlate to filiform-linear (commonly inch or less long and half a line wide), one-

* * * Anomalous species, shrubby, a transition t<> tin- following section, of which it has the 

 foliage and habit, but with broad rather large heads and little-imbricated involucre. 



A. linearifolius, DC. Under.shrub, a foot to a yard or more high, fastigiately much 

 branched, with herbage, oftm ruinous-dotted anil balsamic-viscid: brandies thickly leafy : 

 leaves all narrowly linear (an inch or less long, a line or less wide), sometimes almost filiform, 

 many in axillary fascicles: heads solitary terminating the corymhiform branehlets, on pedun- 

 cles bearing one or two setaceous-subulate bracts: involucre fully half-inch hie;h ; its bracts 

 thin, lanceolate, acute or acuminate, somewhat scarious-margined (at least when dry), in 

 about 2 series of nearly equal length : rays about li>, oblong or broadly lanceolate, in largest 

 heads nearly three-fourths inch long, in smaller only half that length: style-appendages
