* Ptilorid ramosa. 



(?) Stephanomerta runcina^a Nntt. Trans. Am. Phil. Soc. (II.) 7: 



427 ; not Prenanthes rtmcinata James. 



Stems several, from a woody caudex, much branched with spread- 

 ing branches, striate, puberulent below, glabrate above; lower leaves 

 lanceolate, runcinately divided, the lobes narrow, divergent and 

 recurved, the uppermost leaves linear and entire; heads about i cm. 

 long, the bracts oblong, acute; flowers generally 5, reddish purple; 

 achenes glabrous ; pappus plumose to near the base. 



Has been confused with P. faiicifora and P. tenutfolia, having 

 the habit more like the former, but more branched and with broader 

 leaves. The pappus is, however, that of P. tentiifolia. The form 

 of the heads and the color of the flowers are strikingly like those of 

 Lygodesynia juncca. It grows in dry places, on magnesia hills, in bad- 

 lands, etc., at an altitude of 1000-1500 m.
