This plant, gathered by me in the Travesia of Mendoza, in the 

 year 1826, is certainly a distinct species : it bears greatly the 

 habit of L. tenuispinosum, but its branches are straighter, the 

 spines stronger, the leaves larger, the calyx of much greater size 

 and more rigid in its texture, and the stamens are of different 

 structure. It is at once distinguished by its peculiar calyx. The 

 spines measure 2 lines, the leaves, including the petioles, are 3 

 lines long and 1 line broad ; the peduncle is 1 line ; the calyx 

 3 lines in length, the tubular portion being only | line ; the tube 

 of the corolla measures 3 lines, the segments of the border 

 2 lines. 



Var. p. parvifolium, Gill. MSS., is a more intricately nodose 

 plant, becoming with age more glabrous ; the leaves are more 

 linear, smaller, 2 J to 3 lines long, \ line broad : the flowers do 

 not differ from the former in size or structure ; it was found by 

 Dr. Gillies in the Travesia, and is preserved in Sir Wm. Hooker's 

 herbarium.
