Quercus
An oak is a hardwood tree or shrub in the genus ''Quercus'' of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne within a cup. The genus is widely distributed in the Northern Hemisphere; it includes some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene. Molecular phylogeny shows that the genus is divided into Old World and New World clades, but many oak species hybridise freely, making the genus's history difficult to resolve. Ecologically, oaks are keystone species in habitats from Mediterranean semi-desert to subtropical rainforest. They live in association with many kinds of fungi including truffles. Oaks support more than 950 species of caterpillar, many kinds of gall wasp which form distinctive galls (roundish woody lumps such as the oak apple), and a large number of pests and diseases. Oak leaves and acorns contain enough tannin to be toxic to cattle, but pigs are ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

''Quercus coccifera'', the kermes oak or commonly known as Palestine oak, is an oak shrub or tree in section '' Ilex'' of the genus. It has many synonyms, including ''Quercus calliprinos''. It is native to the Mediterranean region and Northern African Maghreb, south to north from Morocco to France and west to east from Portugal to Cyprus and Turkey, crossing Spain, Italy, Libya, the Balkans, and Greece, including Crete. The Kermes oak was historically important as the food plant of '' Kermes'' scale insects, from which a red dye called crimson was obtained. The etymology of the specific name ''coccifera'' is related to the production of red cochineal (crimson) dye and derived from Latin coccum which was from Greek κόκκος, the kermes insect. The Latin -fera means 'bearer'. Description ''Quercus coccifera'' is usually a shrub less than high, rarely a small tree, reaching tall (with specimens recorded in Kouf, Libya).

Quercus Ilex

It is a member of the section (botany), section ''List of Quercus species#Section Ilex, Ilex'' of the genus, with acorns that mature in a single summer. Description It is a large evergreen tree, attaining in favourable places a height of , and developing in open situations a huge head of densely leafy branches as much across, the terminal portions of the branches often pendulous in old trees. The tallest recorded, a tree planted at Windsor Great Park, is 30.4 m tall. The trunk is sometimes over in girth. The young shoots are clothed with a close grey felt. The leaves are very variable in shape, most frequently leaf shape, narrowly oval or ovate-lanceolate, long (rarely to 10 cm long), 2–5 cm wide (rarely to 8 cm wide), rounded or broadly tapered at the base, pointed, the margins usually Glossary of botanical ...
