Quercus canbyi (Canby oak, Sierra oak), synonyms including Quercus graciliformis, is a North American species of oak tree. [2]
Quercus canbyi is a semi-evergreen - evergreen tree, [3] up to 40–50 feet (12–15 metres) tall in cultivation. Although, it can reach up to 80 feet (24 metres) in the wild in Mexico. It starts as a pyramidal form and then matures into an open irregular shape. [4] It can reach a spread of 30–40 feet (9.1–12.2 metres) wide. [5]
The dark, glossy green leaves are 6–8 inches (15–20 centimetres) long and have serrated edges. The petioles can have a reddish hue. [6] It blooms in March and the acorns are then seen in August. [7] [8]
It has been distinguished from Quercus graciliformis by its twig shape and by producing acorns biennially rather than annually; [9] however as of February 2023 [update] , Plants of the World Online regards them as synonymous. [2]
Quercus canbyi was first described by William Trelease in 1924. [2] It is placed in Quercus section Lobatae. [10]
The species has been found only in Texas and in northeast Mexico. [2] [11]
Quercus canbyi was assessed in 2016 for the IUCN Red List as "least concern". [1] Quercus graciliformis, regarded as a synonym by Plants of the World Online, was assessed as "critically endangered" in 2016. [12]
Quercus canbyi will tolerate most kinds of soils and is used in gardens to provide shade. [13]
Quercus ilex, the evergreen oak, holly oak or holm oak is a large evergreen oak native to the Mediterranean region. It is a member of the Ilex section of the genus, with acorns that mature in a single summer.
Quercus emoryi, the Emory oak, is a species of oak common in Arizona, New Mexico and western Texas, United States, and northern Mexico. It typically grows in dry hills at moderate altitudes.
Quercus coccifera, the kermes oak, is an oak bush in the Ilex section 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, 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'.

Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat.
