Mus. Paris (Guillemin, Bertero) ; in hb. Hook. (Bertero, 1448 ; 
Cuming). 
This species is remarkable for its broom-like habit and the 
brancblike length of its extremely slender and lax spines. Bertero 
describes it as a tree 8 or 10 feet in height, with whitish flowers of 
a rose-coloured tint, and as being almost bare of leaves : its leaves, 
however, are larger than in any other species, measuring 9 lines 
in length (including a petiole of 1 line) and 2^ lines broad. 
The pedicels are 1^ line long, the tube of the calyx 2 lines, the 
segments 1 line long, and the tube is 1^ line in diameter; the 
position of the disk is mai’ked by a line of constriction above the 
semiglobose base of the calyx. The fruit, surmounted by the 
persistent style, is nearly globose, 2 lines in diameter, and sup- 
ported by the lax persistent cup of the calyx*.

Chile meridiondis ; in herb, meo (Miller) . 
The above plant was given to me by Dr. Miller, who I believe 
obtained it in the south of Chile, from the neighbourhood of 
Concepcion. Its main branch is perfectly straight, a foot in 
length from where it has been eut ofi", having evidently been 
1 onger ; it is 1^ line in thickness : the primary nodes are 1^ inch 
distant, the secondary and tertiary 3 lines apart ; the primary 
spines or branchlets are 1 to 2^ inches long, gradually decreasing 
upwards ; the secondary spines are 9 lines, the tertiary 3 or 4 
lines long, all terminated by a reddish corneous sharp point ; 
* This species is shown in Plate 35 n of this volume.
