Oak \Oak\ ([omac]k), n. [OE. oke, ok, ak, AS. [be]c; akin to D.       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.          2. The strong wood or timber of the oak.          Note: Among the true oaks in America are:          {Barren oak}, or          {Black-jack}, {Q. nigra}.          {Basket oak}, {Q. Michauxii}.          {Black oak}, {Q. tinctoria}; -- called also {yellow} or             {quercitron oak}.          {Bur oak} (see under {Bur}.), {Q. macrocarpa}; -- called also             {over-cup} or {mossy-cup oak}.          {Chestnut oak}, {Q.

Chrysolepis}, of California.                      {Pin oak}. Same as {Swamp oak}.          {Post oak}, {Q. obtusifolia}.          {Red oak}, {Q. rubra}.          {Scarlet oak}, {Q. coccinea}.          {Scrub oak}, {Q. ilicifolia}, {Q. undulata}, etc.          {Shingle oak}, {Q. imbricaria}.          {Spanish oak}, {Q. falcata}.          {Swamp Spanish oak}, or          {Pin oak}, {Q. palustris}.          {Swamp white oak}, {Q. bicolor}.          {Water oak}, {Q. aguatica}.          {Water white oak}, {Q. lyrata}.          {Willow oak}, {Q.

Ilex}.          {Kermes oak}, {Q. coccifera}.          {Nutgall oak}, {Q. infectoria}.          Note: Among plants called oak, but not of the genus                {Quercus}, are:          {African oak}, a valuable timber tree ({Oldfieldia             Africana}).          {Australian, [or] She}, {oak}, any tree of the genus             {Casuarina} (see {Casuarina}).          {Indian oak}, the teak tree (see {Teak}).          {Jerusalem oak}.
