 Take then the various kinds of oak; for in this tree men recognise more differences than in any other. Some simply speak of a cultivated and a wild kind, not recognising any distinction made by the sweetness of the fruit; (for sweetest is that of the kind called Valonia oak, and this they make the wild kind), but distinguishing the cultivated kind by its growing more commonly on tilled land and having smoother timber, while the Valonia oak has rough wood and grows in mountain districts. Thus some make four kinds, others five. They also in some cases vary as to the names assigned; thus the kind which bears sweet fruit is called by some hemeris, by others 'true oak.' So too with other kinds. However, to take the classification given by the people of Mount Ida, these are the kinds: hemeris (gall-oal), aigilops (Turkey-oak), 'broad-leaved' oak (scrub oak), Valonia oak, sea-bark oak, which some call 'straight-barked' oak. All these bear fruit; but the fruits of Valonia oak are the sweetest, as has been said; second to these those of hemeris (gall-oak), third those of the 'broad-leaved' oak (scrub oak), fourth sea-bark oak, and last aigilops (Turkey-oak), whose fruits are very bitter. However the fruit is not always sweet in the kinds specified as such ; sometimes it is bitter, that of the Valonia oak for instance. There are also differences in the size shape and colour of the acorns. Those of Valonia oak and sea-bark oak are peculiar; in both of these kinds on what are called the 'male' trees the acorns become stony at one end or the other; in one kind this hardening takes place in the end which is
