base by the permanent tube of the calyx, tricoccous, dehiscent. (Don’s 
Mill.) 
Leaves, when present, simple, opposite, stipulate, deciduous ; very minute, 
and quite entire. Flowers axillary, fascicled, or racemose; and, when the 
leaves are absent, rising from beneath the base of the spines. — Much- 
branched shrubs, with divaricating, decussately opposite branches, and spiny 
branchlets. ;

Spec. Char., §c. Spines rigid, simple, or much branched. Peduncles mostly 
in pairs. Calyx ovate-oblong. Stamens sessile. (Lind/.) A spiny shrub, 
evergreen, from the colour of its branches and branchlets. Chili and 
Mendoza, on mountains. Height 3 ft. to 4ft. Introduced in 1823. 
Flowers greenish white, stained with dull purple; May to July. Berry 
whitish, about the size of a small pea; ripe in Sept. y 
The young branches are furnished with “ bright 
green sawed scales” as leaves ; they are placed oppo- 
site, and at the base of each isa small stipule. The ,, 
leaves and stipules speedily fall off, “leaving the ~M@iyy 
branches to act as leaves, by the aid of their soft par- 
enchyma, with which they are clothed in the form of 
bark.” Hence, plants of any size appear one mass of 
naked spiny green branches in winter ; and, in summer, 
having leaves and flowers all over the points of the 
branchlets. It is a most desirable addition to our 
evergreen shrubs; and, as it escaped the winter of 
1837-8, it may be safely recommended as hardy, for cli- 
mates not much colder than that of London. It grows 
in common garden soil, in a dry situation, fully exposed 
to the sun. It has not yet been propagated otherwise 
than by Chilian seeds, which are frequently received 
under the name of Retanilla. We haye no doubt, 
however, that it might be increased by layers, or by 
cuttings in sand under a glass. 
269. Collétea hérrida. 
Other Species of Collétia. — There are plants in the London gardens, under 
the name of C. spinésa and C. wlicina, which we consider merely as varieties 
of C. hérrida; though the former has white flowers, and the latter broader 
leaves than those which we have described. They are considered more ten- 
der than C. hérrida ; but this may possibly be owing to the plants having been

younger, C. E’phedra Vent. Choix, t. 16. (the Rhamnus E phedra Domb., and 
the Retanilla E’phedra Brong.) is said to have survived the criterion winter 
at Liverpool. In jig.270.,a represents C. wlicina; 6, C. E’phedra (Reta- 
nilla E’phedra Brong.) ; and c, C. spinosa. «
