AND THE ADJOINING TERRITORY. 227 



*Oxypetalum solanoides, Hook. At Ajo, Dear Cabo S. 

 Antonio (No. 165, G. C). 



Hydrophyllacej:. 



Phacelia glandulosa, JVutt., var. patagonica. South of 

 province of Buenos Ayres (JSTo. 211, G. C). A very imperfect 

 fragment, but evidently the same as a plant in Kew Herbarium 

 gathered by Darwin at Bahia Blanca, and another from the Pata- 

 gonian coast, sent by Captain Middleton. It differs from the 

 variety neo-mexicana by a smaller corolla and less exserted 

 stamens and style. 



BoRAGINEiE. 



Helioteopium ANcnus^FOLiuM, Poir., var. angustifolidm. 

 Marshes of the Naporta Chico near Bahia Blanca (No. 119 b, 

 G. C). This was collected and sent along with Stemodia lan- 

 ceolata, Benth. 



Heliotropium curassavicum, L., var. parviflorum. Salt- 

 marshes at the mouth of the Eio Negro, and elsewhere in Pata- 

 gonia and Buenos Ayres (No. 221, G. C). 



Ebitrichium ? Valley of the Eio Negro on moist ground 



(No. 199, G. C). lam unable to determine this plant, not find- 

 iug it possible to fix the characters of the numerous American 

 species with minute flowers. It has some resemblance to E. albi- 

 florum, Griseb. (Myosotis albijlora, Banks. & Sol.), but cannot, I 

 think, be referred to that species. Its true position, I believe, 

 either as a variety or as a distinct species, is between E. califor- 

 nicum, A. DC, and E. tenellum, Gray. 



* SOLANACE-&. 



Solanum eleagnifolium, Cav. South of the province of 

 Buenos Ayres (No. 81, G. C). This plant, whose original home 

 is the subtropical zone of South America, appears to have followed 

 the spread of colonization southward. It is very common about 

 inhabited places, and a troublesome weed in cultivated soil. 



Solanum ? About Bahia Blanca, and along the valley 



of the Eio Negro (Nos. 55 and 99, G. C). The Araucanian 

 Indians cook the leaves and eat them as a vegetable, calling the 

 plant LiagM. Without a familiar acquaintance with the plants 

 in their home, it is not easy for a botanist to find his way among
