^ canescently and densely tomentose; the leaves broadly" obovate, 

 toothed, narrowed into a petiole. Heads on short peduncles, ter- 

 minating the somewhat corymbose branches. 



T. (Polydymia) ramosissim.a, n. sp. Hills bordering the Gila. ' 

 Stem spreading, with very numerous matted branches. Leaves 

 about three-fourths of an inch in length, the lamina broader than 

 long, with 5-7 indistinct rounded teeth, abruptly narrowed into a 

 longish petiole. Heads about one-third of an inch in diameter, 

 ovate. Involucral scales in several series, the exterior ones shor- 

 ter than the interior. Hairs of the achenium smooth, slightly bifid 

 at the summit. Pappus longer than the achemum. . This plant is 

 clearly allied to Tetradymia, but differs in the many flowered heads; 

 numerous scales of the involucre; slightly cleft corolla tube, and in 

 several other characters, so that it should perhaps form the type of 

 a distinct genus. . '
