This plant was sent a long time ago from Mexico by 
M. Botteri to Mr. Wilson Saunders, and I knew it for many 
years in the Reigate collection. When this was dispersed 
it was purchased by Mr. J. T. Peacock, with whom it 
flowered, at Sudbury House, Hammersmith, in the spring of 
1875. I have not been able to refer it to any of the species 
described in the elaborate monograph of the late General 
Von Jacobi. It is a Zittea ag regards inflorescence, and, 
according to his classification, founded on characters, falls 
into the group “ Subcoriacee,” which combines the small 
teeth of the “ Aloides,” with a much thinner leaf, with the 
firmer texture of the large-spined panicled species of the 
series of which 4. americana and Scolymus are best known 
representatives. Its nearest neighbours are 4. densiflora, 
Hook. in Bot. Mag., t. 5006, the plant called 4. Keratto, 
by Salmdyck and Jacobi (which is not the original Keratto 
of Miller), and 4. zalapensis, Roezl; Jacobi Monog., 72, 
which I cannot distinguish from A. polyacantha “ Haworth,’ 
K. Koch; but in all these the leaves are at least five or six 
times as long as broad, oblanceolate, not oblanceolate-oblong. 
Descr. Leaves 40-50 in a sessile rosette, oblanceolate- or ob- 
long-spathulate, two feet long, six to eight inches broad above 
the middle, narrowed gradually to a pungent dark-coloured 
channelled spine half an inch long, and downwards to a breadth
