218 MR. .T. BALL ON THE FLORA OF NORTH PATAGONIA 



Crassulace^;. 

 Tilljea muscosa, L., var.,=T. minima, Mers. South of pro- 

 vince of Buenos Ayres and North Patagonia (No. 156, G-. C). 

 This was gathered by Darwin at Bahia Blanca. 



HaLORAGEJE. 



Mtriophyllum ? Streams at Bahia Blanca (No. 123, 



G. C). This has neither flower nor fruit, but is almost certainly 

 M. proserpinacoides. It also grows in Entrerios (No. 122, G. C). 



Lythrarie.e. 

 Cuphea spicata, Cav., var. racemosa, Koehne ? Marshes of 

 the Naporta Chico, Bahia Blanca (No. 117, G. C). I do not feel 

 certain of the identity of this with the Uruguay plant of Koehne, 

 but it is certainly very near to C. spicata. 



Onagrarie-j:. 

 (Enothera mendocinensis, Gill. Bahia Blanca and North 

 Patagonia (No. 137, G. C). It is called Balsamo by the Spaniards, 

 and by the Indians Inulei, and is used for application to wounds. 

 This, which was collected by Darwin in Patagonia, differs from 

 CE. odorata, Jacq., in being altogether more glabrous, and having 

 the leaves more attenuated at the base, but I doubt whether it 

 should be ranked as more than a variety of that species. It is 

 doubtful whether CE. mollissima, L., should not be included 

 under the san^e specific type. 



Loasace^;. 

 Mentzelia albescens, Griseb., = Bartonia albescens, Gill. 

 North Patagonia (No. 92, G. C). This species is widely spread 

 throughout temperate South America. 



Loasa prostrata, Gill. ? Sierra de la Ventana, near Bahia 

 Blanca (Nos. 61 & 107, G. C). I am somewhat doubtful as to 

 this. The species of Loasa are very variable, and their limits ill- 

 defined. 



Blumenbachia multifida,= Loasa multifida, C. Gay. In 

 woods at Ajo, near Cabo S. Antonio (No. 167, G. C). Called 

 Amor seco by the Spaniards. 



Grammatocarpus volubilis, Presl. Bahia Blanca and North 

 Patagonia (No. 176, G. C). Araucanian name Fueo. Gathered 

 by Darwin at Bahia Blanca.
