Similar to this is the carob-tree, by the Ionians known as the “ceraunia,”[846] which in a similar manner bears fruit from the trunk, this fruit being known by the name of “siliqua,” or “pod.” For this reason, committing a manifest error, some persons[847] have called it the Egyptian fig; it being the fact that this tree does not grow in Egypt, but in Syria and Ionia, in the vicinity, too, of Cnidos, and in the island of Rhodes. It is always covered with leaves, and bears a white flower with a very powerful odour. It sends forth shoots at the lower part, and is consequently quite yellow on the surface, as the young suckers deprive the trunk of the requisite moisture. When the fruit of the preceding year is gathered, about the rising of the Dog-star, fresh fruit immediately makes its appearance; after which the tree blossoms while the constellation of Arcturus[848] is above the horizon, and the winter imparts nourishment to the fruit. CHAP. 17. (9.)—THE PERSIAN TREE. IN WHAT TREES THE FRUITS GERMINATE THE ONE BELOW THE OTHER. Egypt, too, produces another tree of a peculiar description, the Persian[849] tree, similar in appearance to the pear-tree, but retaining its leaves during the winter. This tree produces without intermission, for if the fruit is pulled to-day, fresh fruit will make its appearance to-morrow: the time for ripening is while the Etesian[850] winds prevail. The fruit of this tree is more oblong than a pear, but is enclosed in a shell and a rind of a grassy colour, like the almond; but what is found within, instead of being a nut as in the almond, is a plum, differing from the almond[851] in being shorter and quite soft. This fruit, although particularly inviting for its luscious sweetness, is productive of no injurious effects. The wood, for its goodness, solidity, and blackness, is in no respect inferior to that of the lotus: people have been in the habit of making statues of it. The wood of the tree which we have mentioned as the “balanus,”[852] although very durable, is not so highly esteemed as this, as it is knotted and twisted in the greater part: hence it is only employed for the purposes of ship-building.
