. This plant was raised in England many years since, and then 

 erroneously supposed to be a hybrid, or a monstrosity of C. 

 spinosa, and was described by Dr. Lindley under the name of 

 C. Bictonensis. It is the most remarkable species of the genus, 

 on account of its monstrous spines, which are flattened, and 

 extend from one axil to another in cruciating and divaricating 

 pairs : they are nearly an inch long and 3 to 6 lines broad at 

 their base. Its leaves are very caducous, oblong, acute, with a 

 mucronate apex, more obtuse at the base, fleshy, obsoletely 3- 

 nerved, toothed on the margin, quite glabrous, 2 lines long, 

 1 line broad, on a slender petiole of 1 line in length ; this springs 

 out of a sinus of a bidentate acute stipule, also caducous. The 

 flowers are smaller than in any of the preceding species, and 

 are of a whitish colour : the length of the tube is 1 j line, of its 

 reflected segments 1 line, its diameter 1 line. The annular peri- 

 gynous disk] is green, and situated near the base of the tube ; 

 the filaments are one-fourth of the length of the segments, and 

 are reflected within the mouth; the style is exserted. The 

 capsule is 2J lines in diameter, 3-lobed, and seated in the free 

 cupular persistent base of the calyx*.
