Senecio adenophyllus Meyen & Walp. in Nov. Act. Nat. Cur. 



19: Suppl. 1, p. 282. 1843; Walp. Rep. 6:271. 1846-47; Wedd. 

 Chlor. And. 1:112. 1855-57. 



Bolivia: vicinity of Oruro, August 18, 1914, Mr. & Mrs. J. N. 

 Rose 18932 (U. S. Nat. Herb, and Mo. Bot. Gard. Herb.).

 Mrs. J. N. Rose 18951 (U. S. Nat. Herb, and Mo. Bot. Gard. 

 Herb.). 



The leaves of this species are apparently quite variable in 



size and outline. Walper's description reads "foliis sessilibus 

 confertis ovato-lanceolatis acuminatis grosse serratis vel subin- 

 tegris lineari-lanceolatis." In the Gray Herbarium there is a 

 drawing of Meyen's original material from Peru which shows a 

 narrowly lanceolate, coarsely and irregularly dentate form of 

 leaf. Although the leaves on the specimens above cited are 

 narrower than they would appear to be in the type, yet the 

 specimens collected by Mr. and Mrs. Rose in all probability 

 represent a narrow-leaved form of the above species.
