  • Interesting fact: In a day, a mature oak tree can draw approximately 50 gallons of water
    • Oak (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.
    • Oak The strong wood or timber of the oak.

  • Interesting fact: Oak trees do not produce acorns until they are fifty years of age or older
    • n oak A tree or shrub of the genus Quercus, a large and widely dispersed group, chiefly of forest-trees. In its nobler representatives the oak as “the monarch of the forest” has always been impressive, and it anciently held an important place in religious and civil ceremonies. Oak chaplets were a reward of civic merit among the Romans; the Druids venerated the oak as well as the mistletoe which grows upon it. The timber of many species is of great economic value, and the bark of several is used for tanning and dyeing and in medicine. (See oak-bark and quercitron.) One species furnishes cork (see cork). The fruit-cups of some are used in tanning (see valonia). (See also gall, kermes, and kermesoak.) The oak of English history and literature is chiefly the British oak, Quercus Robur, having two varieties, pedunculata and sessiliflora, often regarded as species. The species is distributed throughout a great part of Europe and in western Asia. It attains great age, with an extreme height of 120 feet. For ship-building its timber is considered invaluable, having the requisite toughness and most other qualities without extreme weight, and until recently it was the prevailing material of British shipping. It is also used for construction, cabinet-work, etc. Its bark is a tanning substance of great importance. In the eastern half of North America the white oak, Q. alba, in England sometimes called Quebec oak, occupies a somewhat similar but less commanding position. It rises from 70 to 140 feet, and affords a hard, tough, and durable wood, used, though not equal to the English oak, in ship-building, construction of all sorts, the manufacture of carriages and implements, cabinet-making, etc. The bur, overcup, or mossy-cup oak. Q. macrocarpa, is a tree of similar range, equal size, and even superior wood, which is not always distinguished from that of the white oak.
