This species is recognized by the unusual length and distance 
of its spines, which are somewhat cuiwed, and not stout. The 
branchlets, in my specimen, are about 7 inches long, and barely 
a line in diameter : the primary spines are from 1 to 2 inches 
long, and about | 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, decmTent 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 | line long; it is | 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 lon^-er, 
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 eachf.
