    eik, G. eiche, OHG. eih, Icel. eik, Sw. ek, Dan. eeg.]
    1. (Bot.) Any tree or shrub of the genus {Quercus}. The oaks
    have alternate leaves, often variously lobed, and
    staminate flowers in catkins. The fruit is a smooth nut,
    called an {acorn}, which is more or less inclosed in a
    scaly involucre called the cup or cupule. There are now
    recognized about three hundred species, of which nearly
    fifty occur in the United States, the rest in Europe,
    Asia, and the other parts of North America, a very few
    barely reaching the northern parts of South America and
    Africa. Many of the oaks form forest trees of grand
    proportions and live many centuries. The wood is usually
    hard and tough, and provided with conspicuous medullary
    rays, forming the silver grain.
