This specimen was given to me by Dr. IVIiller, who I believe 

 obtained it in the south of Chile, from the neighbourhood of 

 Concepcion. Its main branch is perfectly straight, a foot in 

 length from where it has been cut off, having evidently been 

 longer; it is 1| line in thickness : the primary nodes are 1| inch 

 distant, the secondary and tertiary 3 lines apart ; the primary 

 spines or branchlets are 1 to 2| inches long, gradually decreasing 

 upwards ; the secondary spines are 9 lines, the tertiary 3 or 4 

 lines long, all terminated by a reddish corneous sharp point ; 

 the leaves, including the petiole, measure only a line in length, 

 and \ line in breadth; the flowers are small, and of a pale 

 whitish colour ; the peduncle is | line long, the tube of the calyx 

 1| line in length, the segments h line long, the tube barely 

 \ line in diameter*.

 berculo stipula sustentato infra singulam spinam ortls, vel e 

 medio spinse nascentibus : pedunculo flore paulo breviore, 

 calycis tubo late cylindrico, limbi laciniis 4-5, oblongis, acutis, 

 reflexis, staminibus totidcm, erectis, laciniis dimidio breviori- 

 bus, stylo vix exserto. — Chile. — v.s. in herb.meo (Bridges, 140) ;

 raiso (Gaudichaud, 12G8) ; Monte La Leone (Bertero) ; Val- 

 divia, Rio Callecalle (Lechler, 391). 



The species is recognized by the unusual length and distance 



of its spines, which are somewhat curved, and not stout. The 



branchlets, in my specimen, arc about 7 inches long, and barely 



a line in diameter : the primary spines are from 1 to 2 inches
