westward and southward through Patagonia (No. 97, G. C). The 

 Indians call this plant Mm nim, and chew the root to allay thirst. 

 A decoction is also used with a compress for headache. M. 

 Claraz's specimen is named Gaillardia Doniana on the authority 

 of Lorentz ; but there must be some mistake, as that is a very 

 different plant. 



*Bidens ciieysanthemoides, Michx. A.bout Cabo S. Antonio, 

 in inhabited places (No. 195, G. C). Probably spread by the 

 agency of man. B. helenioides, H. B. K., seems to be a form of 

 the same species. 



Flaveeia Contbayeeva, Pers. Bahia Blanca (No. 51, G. C). 

 Perhaps an introduced plant ; but its use as a yellow dye is known 

 to the Indians. 



Tagetes ? Bahia Blanca (No. 220, G-. C). An imper- 

 fect specimen which I have been unable to make out. Even the 

 genus is uncertain. 



Gaillabdia megapotamica, Spreng., var. scabiosoides, Baker, 

 = Cercostylos scabiosoides, Am. Bahia Blanca and North Pata- 

 gonia (No. 75, G. C). The Araucanian name is Tschdike catschu, 

 meaning Ehea-grass. The leaves are very aromatic, and the 

 infusion is used as a sudorific. It is an illustration of the justice 

 of the precept of M. Alphonse de Candolle, that you should never 

 attribute to an author a name which he has not used, to observe 

 that this species is cited by Grisebaeh (' Plantas Lorentziaii®,' 

 P- 140, and 'Symbols? ad floram Argeutinam,' p. 199), as "Gail- 

 lardia scabiosoides, Benth. Hook." If the authors of the ' Genera' 

 had undertaken to name the species, they would probably have 

 formed the same conclusion as Mr. Baker has expressed in the 

 ' Flora Brasiliensis.' 



Senecio pinnatus, Poir. Sierra de la Ventana and North 

 Patagonia (No. 78, G. C). The Araucanian name is Tschacalia. 



Senecio pinnatus, Poir., var. ? glandulosus. Bahia Blanca, 

 and through North Patagonia (No. 98, G. C). I am somewhat 

 doubtful as to this being referred to a form of S. pinnatus. It 

 closely resembles S. punctatus, Hook. & Arm, which has been by 

 Mr. Baker united to S. pinnatus ; but this specimen differs from 

 all the forma of that species in the rather dense glandular pubes- 

 cence of the upper ramifications and the involucres.
