erect, the longer prostrate; stems yellowisli-red: leaves all 

 radical, tomentose on both sides, oblong-lanceolate, taper- 

 ing into a longer petiole: bracts linear-acuminate and pun- 

 gent: involucres scattered, spreading; tube nearly cylindrical, 

 tomentose. 4-5 mm. long, at length mucli surx3assed by three 

 bj-oad, somewhat recurved, subequal, straight-awned lobes, 

 tomentose above, near the base; the intermediate ones 

 nearly obsolete: perianth yellow, glabrous, shortly stipitate, 

 exserted J its length ; segments ovate-acuminate, entire or 

 crenate on the margins, less than J the length of the tube: 

 stamens 9, attached near the base of the tube; filaments 

 glabrous, exserted; anthers oblong: ovary nearly as long as 

 the tube; embryo straight, linear; radicle J as long as the 

 cotyledons, — Calmalli. 



Chokizanthe mutabilis. Branching at the base, erect or 

 procumbent, 3-12 inches long: stems stramineous, reddish
