Quercus suber, commonly called the cork oak, is a medium-sized, evergreen oak tree in the section Quercus sect. Cerris.It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls.
The bark of the cork oak is used to produce cork stoppers for wine bottles. This species grows around the Mediterranean Sea; Portugal, Spain, Algeria, and Morocco produce most of the world's supply. [90] Acorns of various oak species have been used as food for millennia, in Asia, Europe, the Middle East, North Africa, and among the native ...
The flowers are wind-pollinated catkins produced in mid spring, maturing about 18 months after pollination; the fruit is a globose acorn, 1.5–2 cm (5 ⁄ 8 – 3 ⁄ 4 in) diameter, two-thirds enclosed in the acorn cup, which is densely covered in soft 4–8 millimetres (3 ⁄ 16 – 5 ⁄ 16 in) long 'mossy' bristles.

Many species of oak, chestnut, and beech (genera Quercus, Castanea, and Fagus, respectively) are commonly used as timber for floors, furniture, cabinets, and wine barrels. Cork for stopping wine bottles and a myriad other uses is made from the bark of cork oak, Quercus suber. Chestnuts are the fruits from species of the genus Castanea.
Quercus cornelius-mulleri acorns. Quercus cornelius-mulleri is a North American species of oak known by the common name Muller oak, or Muller's oak. It was described to science in 1981 when it was segregated from the Quercus dumosa complex and found to warrant species status of its own. [3] [4] [5] It was named after ecologist Cornelius Herman ...
California physician and botanist (and one of the founding fathers of the California Academy of Sciences) Albert Kellogg described an oak in an 1855 publication as Quercus arcoglandis (spur acorn oak), [10] apparently the same species as Q. wislizeni. This clearly predates French-Swiss botanist de Candolle's 1864 name, and if confirmed to be ...
Together with larva of the filbertworm moth (Cydia latiferreana), the filbert weevil feeds on the acorns of several species of oak tree. In British Columbia, up to 66% of acorns from garry oak (Quercus garryana) were infected with these larvae. These acorns are still able to germinate, but the germination rate is lower than for uninfected nuts. [2]
