The leaves are some four feet in height, and six inches 

 in breadth, saving at the base where they spread, and the

 ones spreading, all glaucous green, armed at the point 

 with a stout brown spine, and at the edges with white, or 

 sometimes faint red ones, but much smaller. Native of

A. Karatto. — This is a handsome strong-growing plant. 

 The leaves are somewhat spreading and incurved, about 

 four feet long, and some three or four inches wide about 

 the centre, where they are widest, pea green in colour, the 

 spines on the margins small, and reddish brown, whilst 

 the terminal one is stout and of the same colour. Native 

 of Tropical America. 



A. KelloaMi, — This is one of the most distinct, and at 

 the same time most beautiful of the genus. The habit is 

 compact and erect, spreading gracefully with age ; leaves 

 from three to four feet in height, and two to four inches 

 in breadth, very glaucous on both surfaces, armed at the 

 apex with a long, stout, black spine, and clothed at the ■ 

 margins with small closely set white teeth. We found 

 this as a unique plant at Stamford Hill, Middlesex, in 

 the beautiful collection of the enthusiastic and generous 

 amateur whose name it bears. Native of Jalapa, Mexico,
