20b. Artemisia dracunculus glauca (Pallas.) — Plant silky on the young parts and 

 glabrate or glabrous from the beginning (minor variation 4, A. dracunculoides Pursh), 

 inodorous; leaves 3 to 8 cm. long, 1 to 4 mm. wide, rather thick and firm; branches of 

 the panicle comparatively dense, inclined to droop at the ends because of the slender 

 branches, the peduncles mostly less than 2 mm. long; involucre 2 to 3 mm. broad. Ap- 

 parently there are Siberian variations with wider leaves and others with larger heads.

 Chihuahua, New Mexico, and British Columbia; also in Siberia. Specimens from the 

 San Bernardino Mountains and Catalina Island, California, sometimes referred here 

 belong to subspecies typica. Type locality, Siberia. Collections, mostly of the glabrous

 or finely canescent on all the young parts, in age glabrous, or occasionally glabrous from 

 the beginning, inodorous; leaves 3 to 8 cm. long, 2 to 6 mm. wide, rather thin and soft;

 the slender peduncles (sometimes drooping) 2 to 5 mm. long; involucre 2 to 2.5 mm. broad.
