GREENMAN — SOUTH AMERICAN SENECIOS 87 



Bolivia: without locality, Bang 1890 (Mo. Bot. Gard. Herb., 

 Phil. Acad. Nat. Sci. Herb., Gray Herb., and U. S. Nat. Herb.). 



The specimen here cited agrees in all essential characters with 

 the original description and illustration of the above species. 

 Mr. Bang's No. 1890 was referred doubtfully by Doctor Rusby, 

 Bull. N. Y. Bot. Gard. 4:397. 1907, to S. rhizomatus Rusby from 

 which it is amply distinct. 



Senecio nubigenus HBK. Nov. Gen. & Sp. 4:174. 1820. 



S. pimpinellijolius var. nubigena (HBK.) Hieron. in Engl. 

 Bot. Jahrb. 28:034. 1901. 



Ecuador: Pichinca, alt. 3350 m., March, 1864, Jameson (U. S. 



Nat. Herb.) ; vicinity of Santa Rosa de Cahar, September 14, 



15, 1918, Rose & Rose 22669 (U. S. Nat. Herb, and Gray Herb.). 



The specimens here cited agree in all essential characters with 

 the original description of the above species, although in some 

 respects they correspond equally well to S. pimpinellaefolius 

 HBK. In foliar characters, however, the material at hand seems 

 to accord more closely with S. nubigenus. Further collections, 

 upon comparison with the types, may prove the two species, as 

 characterized by Kunth, to be conspecific.
