COLLETIA CRUCIATA (_syn C. bictonensis_).--Chili, 1824. With flattened

woody branches, and sharp-pointed spines which take the place of

leaves, this is at once one of the most singular of hardy flowering

shrubs. It forms a stout dense bush about 4 feet high, and bears

quantities of small white flowers, which render the plant one of great

beauty during the summer months.

C. SPINOSA.--Peru, 1823. This species grows fairly well in some parts

of England and Ireland, and is a curious shrub with awl-shaped leaves,

and, like the other members of the family, an abundant producer of

flowers. It thrives best as a wall plant, and when favourably situated

a height of 12 feet is sometimes attained.
