the many hundred species of Solatium described from South 

 America. This is certainly the same as Argentine specimens 

 (unnamed) preserved in Kew Herbarium from Twecdie and 

 Miers. It is nearest to S. Tweedianum, Hook., but much smaller 

 than that species. Whether it should be ranked as a variety or 

 as a distinct species, I will uot attempt to determine. 



Piiysalis viscosa, L. This is widely spread from Entrerios 

 through the province of Buenos Ayres to the Eio Negro, and be- 

 yond it in North Patagonia, but always near inhabited places (No. 

 175, G. C). This is commonly called Camanbu, a Griiarani name, 

 showing that the plant has spread from the north {i. e. Brazil) 

 The same name is given to the fruit of another Solanaceous plant 

 which has also spread from South Brazil to Patagonia, Salpichroma 

 rhomboidewn, Miers*. The Araucanian Indians have no name for 

 the present species, but call the fruit Kilien, the name given to 

 the Strawberry {Fragaria chilensis).

 S. Am. PL ii. p. 130. Bahia Blanca and through North Pata- 

 gonia (No. 158, G-. C). This is common about Buenos Ayres, 

 but appears to have been introduced there. The Araucanian 

 name is Tschayem. This is a small bush, 2-3 feet in height, 

 with feeble branches, which, when not supported, usually rest 

 on the ground. 



Lyoium ? Bahia Blanca ; Sierra de la Ventana; North 



Patagonia (No. 208, G. C). Araucanian name Ruingan, called 

 by the Spaniards Mataperro, probably because dogs, attempting to 

 penetrate the bushes, are seriously injured by the sharp tough 

 spines. I cannot identify this with any described species ; but as 

 there are several of which I have not seen specimens, I hesitate to 

 give this a name. It agrees with an unnamed specimen in Kew 

 Herbarium from the Eio Negro, from Wilkes's Exploring Expedi- 

 tion, and approaches L. elongatum, Miers ; but is, I think, certainly 

 different. In the present plant the calyx is minute, with very 

 short segments, the corolla attenuated, almost entire, scarcely 

 lobed, but rather crenated at the mouth ; the pedicels, which are 

 very short in flowering-time, are somewhat elongated when the 

 plant bears its 'bright-red berries. The leaves are small, linear- 



* T may remark that the locality " Magellania," given by Dunal in PC. 

 Prod, for this Salpkhroma, on- the supposed authority of Commerson, is au in- 

 dubitable mistake. Cominerson found the plant mar Monte Video.
