216 MB. J. BALL ON TIIE FLORA OF NOBTH PATAGONIA 



(No. 109, G. C). A. incana, Vogel, seems to be too near to this 

 species. 



Adesmia pendula, DC. Bahia Blanca; Cabo S. Antonio; 

 North Patagonia (No. 228, G. C). This is a yellow-flowered 

 species. The specimen represents a small form. 



Adesmia ? Bahia Blanca (No. 110, G. C). The speci- 

 men is too imperfect for determination, but is apparently the 

 same as an unnamed specimen in Kew Herbarium from M;il- 

 donado, collected by Lieut. Carr. 



Adesmia ? Valley of the Bio Colorado. Collected in 



March (No. 206, G. C ). The specimen (wanting leaves and 

 fruit) is too imperfect for determination, but appears to be near 

 A. longipes. 



*Ervum hirsutum, L. In a wood at Ajo (No. 169, G-. C). 

 Doubtless introduced from Europe. Not mentioned by C. Berg 

 in his ' Enumeracion de las Plantas Europeas que se hallan como 

 silvestres en la provincia de Buenos Ayres y en Patagonia.' 



Ehtncosia Senna, Gill., \&r.foliolis lanceolatis Sierra de la 

 Ventana, near Bahia Blanca (No. 80, G-. C). 



Ehtncosia Senna, Gill., Y&r.foliolis late ovatis. Bahia Blanca 

 (No. 189, Gh C). This species,origiually described from Chilian 

 specimens, appears to be widely spread from Texas and Mexico 

 to the borders of Patagonia. I do not think that R. texana, Torr. 

 & Gr., can be separated from it. It is an insignificant climber, 

 with small yellowish flowers. 



Rosacea. 

 Mabgybicabpus setosus, Ruiz Sf Pav. Bahia Blanca (No. 

 66, G. C). Called by the Spaniards " Yerba de la perdiz," which 

 is merely a translation of the Araucanian name Silio lahuen, Silio 

 meauing partridge, and lahuen remedy. The Tinamous (Nothura 

 maculosa, Temm.), or so-called partridges, of South America, are 

 used to eat the fruit. This species was collected at Bahia Blanca 

 by Darwin. 



Margyricarpus ? Sierra de la Ventana and North Pata- 

 gonia (No. 67, G. C). This is probably a variety of M. setosus, 

 but is prostrate and much more robust, bearing to it much the 

 same relation that Juniperus nana does to slender forms of Juni- 

 per us communis.
