armed at the edges, the lower ones recurved, the upper 

 ones erect, from two to three feet in length, and very 

 dark green in colour. It forms a compact handsome plant. 

 Native of South America. 



A. geminiflora filifera. — In all respects resembling the 

 preceding, except that the leaves are somewhat profusely 

 clothed with long white filaments ; it is, therefore, easily 

 distinguished. It is frequently obtained from seeds of 

 A. gemmiflora, and, consequently, can only be a variety 

 of that plant. 



A. Ghiesbreghtii. — A distinct aiid fine plant. The leaves 

 curve inwards slightly, and are of a dark bright green 

 colour, bordered with red, and armed at the edges and 

 point with large bright red spines. Native of Mexico. 



A. glcmceseens. — This species rises with age upon a stemi 

 some six feet in height. The leaves are from two tO' 

 two and a half feet in length, and about eight inches 

 across in the widest part, somewhat spathnlate, tapering 

 to a point, very glaucous on both sides, and quite des- 

 titute of spines either at the apex or margins. Native- 

 of Mexico. 



A. Mookerri. — An extremely rare species, a fact which 

 is much to be regretted, for it is a noble plant, peculiarly 

 attractive amongst a collection of this genus, on account 

 of its massiveness. The leaves are spathulate, recurved 

 at the apex, from four to five feet in length, and six to- 

 eight inches across in the widest part ; they are very thick 

 and fleshy, light green, in a young state slightly glaucous, 

 deeply lobed at the edges, and each lobe is armed -with 

 a large flat brown spine, and the apex with a long, terete,, 

 and very stout one. Native of Mexico. 



A. horrida. — A small-growing dwarf species, with broad, 

 oval-lanceolate, concave leaves, about four inches long,.
