spathulate. If, as I believe, undescribed, it ma}' properly be 

 called Lycium Wilkesii. 



Oestrum Parqui, I? Her., var. South of the province of 

 Buenos Ayres (Nos. 174 and 219, G. C). This species, almost 

 universal in South America, is extremely variable. M. Claraz's 

 specimen represents a small and slender form. 



Petunia nvctaginiflora, Juss. North Patagonia, Sierra de 

 la Ventana, Sierra de Tandil (No. 192, G-. C). This was known 

 to extend from South Brazil to Buenos Ayres ; but M. Claraz 

 has added considerably to its known area. 



Nierembergia hippomanica, Miers. On the dry stony and 

 rocky plateaux near Bahia Blanca, find through North Patagonia 

 (No. 135. G. C). 



Nierembergia rigida, Miers. Common about Bahia Blanca 

 (No. 144, Gr. C). This is very near to, and perhaps only a variety 

 of, N.Jilicaulis, Lindl. 



SCROPHULAKINE.E. 



Linaria canadensis, Spr. Banks of the Naporta near Bahia 

 Blanca (No. 72, Gr. C). This has possibly been introduced by 

 man ; but the species is very widely Bpread through the American 

 continent. 



Stemodia lanceolata, Benth. Marshes of the Naporta Chico 

 near Bahia Blanca (No. 119, G. G). Flowers of a violet-blue 

 tint. This species appears to extend from the northern provinces 

 to the extreme south of the Argentine territory. 



Herpestis radicata, Bentham. Same locality as the last 

 species (No. 118, G. C). 



Scoparia flava, Cham, et Schlecht. Same locality as the two 

 preceding species (No. 118 b, G. C). 



Gerardia genistvefolia, Cham, et Schlecht. Sierra de la 

 Ventana and Sierra de Tandil (No. 161, G. C). Flowers full 

 rose-colour. 



Verbena ce^;. 



Lantana Clarazii, n. sp. Plateaux of North Patagonia above 

 the valley of the Bio Negro, flowering in spring (September) 

 (No. 214, G . G). I subjoin a brief description of this very distinct 

 plant : —
