Quercus canariensis is a species of evergreen broadleaf flowering plants (in the Fagaceae or Beech family), native to the southern Iberian Peninsula and north-west Africa. It is a medium-sized to large tree of 20–30 metres, and up to 35 metres in Algeria. Its bark is grey-brown and rugged, with many fissures that are irregularly arranged but predominantly vertical, similar to other oak species.
Quercus canariensis bears leaves all year, being most sparsely arrayed in early spring. When new leaves open in spring they are light yellow-green. They soon become darker, but remain slightly glossy; some of them turn brown later in the year, before falling. They are fairly large and broad, roughly oval, with six to a dozen rounded shallow lobes on each side, and veins running forwards to the the lobes from the central axis. It has strings of catkins in spring, and grows acorns in cups, turning brown in autumn, similar to those of Quercus robur, the common oak
Quercus canariensis grows naturally in moist well-drained humid forests. In its native range it is a tree of ecological importance, and was an important source of timber for ship-building in Spain and Portugal in past centuries. As well as in Britain, it is widely cultivated in Australia and New Zealand. Despite its scientific specific name, it is not native in the Canary Islands. The International Oak Society provides an article with further information about this species.

Turn on a flashing dot which tracks your live location on the map, surrounded by a circle indicating the accuracy of the location. This will work only if your device has a satellite navigation (GPS etc.) receiver which is enabled and can acquire a signal. You will probably be asked to allow the website to access "location services" the first time you press this button. The button flashes orange while trying to locate you, and green while your location is shown. Press it again to turn it off.
