long, and about J inch apart; the secondary spines are from 

 7 to 10 lines long : the oblong leaves, with a toothed margin, 

 are 3 to 5 lines long, 1| to 2| lines broad, decurrent on a deeply 

 channelled deflected petiole 1 line long; the nervures are sul- 

 cated on the upper surface, and prominent beneath : the flowers 

 are small and pale, clustered together upon a large scaly tubercle ; 

 the pedicels are 1 line long, the tube, contracted for some length 

 in the middle, is 2 lines, and its segments f line long; it is j line 

 in diameter : the peduncle in fruit is thicker, 2 lines long, and 

 the 3-lobed capsule is 2| lines in diameter. In Bridges's and one 

 of Bertero's specimens, the spines are much stouter and longer, 

 much paler, yellowish, being 1| to 2| inches long, and a line or 

 more in thickness, and they bear no spinelets, but two pairs of 

 floriferous nodes upon each*. 



Var. /?. insularis : spinosissima, spinis iterumque spinosis, vali-

 This variety is very dissimilar in appearance to the fore- 

 going, but has no tangible differential characters; it is of a 

 darker olivaceous hue, and quite glabrous ; the primary spines 

 are 8 lines apart and 1| to 2 inches long, the secondary spines 

 3 lines apart and 6 to 9 lines long; the pedicels 1| line long, 

 and the flowers are like those of the preceding.

The drawing and floral analysis I made of this plant thirty- 

 five years ago are still preserved, but my specimens were lost by 

 shipwreck. I have still many of its seeds, which enabled me to 

 investigate the seminal structure given in a preceding page. 

 The species is closely allied to C. armata, but differs in its much 

 closer axils and much shorter spines; the floral pedicels are
