From Professor Macloskie I received a specimen of a Senecio collected 

 by Hatcher in the Cordilleras of South Patagonia and determined by 

 Prof. Dr. O. Hoffmann as S. pachyphyllus Remy. Dr. Hoffmann had 

 an opportunity to compare Hatcher's specimens with a specimen collected 

 by Dr. R. A. Philippi and by him referred to S. pachyphylfas. My own 

 specimens exactly agree with the specimen sent me by Prof. Macloskie. 



In order to determine my specimen I had at my disposal no authentic 

 specimen of S. pachyphyllus, but only the diagnosis given by Remy in 

 Gay, Flora Chil., vol. iv., p. 147. The leaves of S. pachyphyllus are there 

 described as follows: "foliis crassissimo-cylindraceis . . . acutis," which 

 does not agree with my plant, its leaves being quite plane, but somewhat 

 fleshy, and hardly acute. And further, S. pachyphyllus is described as 

 quite glabrous, while my plant (being for the most part glabrous) is pilose 

 on the margins of the leaf-sheaths, and of the basal parts of the scape- 

 leaves, as well as on the margins of the outer scales. 



I have therefore separated my plant from S. pachyphyllus. The two 

 species, however, are near to each other. 



Is known from the eastern slopes of the cordilleras, and grows in open 

 humid places, in South Patagonia, near Lago San Martin (250-500 m.), 

 and in Mid-Patagonia near Lago Buenos Aires. D.

S. MICROFOLIUS DC. 



Is also identical with S. patagonicus Hook. & Arn., and should con- 

 sequently be deleted. D. 



S. MISER Hook. fil. var. TEHUELCHES Speg. 



Probably belongs to S. longipes, as remarked by Skottsberg in his paper, 

 "Zur Flora des Feuerlandes," p. 33. I am not very decided in this
