The citron-tree,[1] the juniper, and the holm-oak are looked upon as having fruit on them the whole year through, and upon these trees we see the new fruit hanging along with that of the preceding year. The pine, however, is the most remarkable of them all; for it has upon it at the same moment the fruit that is hastening to maturity, the fruit that is to come to maturity in the ensuing year, and the fruit that is to ripen the next year but one.[2] Indeed, there is no tree that is more eager to develope its resources; for in the same month in which a nut is plucked from it, another will ripen in the same place; the arrangement being such, that there is no month in which the nuts of this tree are not ripening. Those nuts which split while still upon the tree, are known by the name of azaniæ;[3] they are productive of injury to the others, if not removed.
