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.
