2. Ceratonia siliqua, (Carob bean).

This is a native of the Mediterranean region. It requires a good rich soil and a warm climate; it would probably succeed in the northern part of the Auckland District. The fruit of the carob contains a russet, insipid edible pulp of great value as forage. The carob should be grown in clumps, as the male and female flowers are borne on separate plants. In countries where it is extensively grown the practice is to graft one branch of the male to each plant of the female.
