The Holm Oak (Quercus Ilex), which skirts the Mediterranean coast of Europe, and seems to thrive best, even in England, when exposed to sea breezes, is the Ilex, famous in classical literature. Its evergreen leaves resemble those of the holly, whose generic name is Ilex. This is one of the most ornamental of the oaks, compact and regular in form, and beautiful in its glossy foliage the year round. Its acorns form one of the important edible sorts in Europe. The value of its mast alone would justify the planting of the Holm oak. It is also one of the truffle oaks, and its bark and the galls of one of its varieties are of the highest value in dyeing and tanning.
