Shrub or small tree reaching up to 4 m tall. Shoots glabrous or sparsely hairy when mature. Leaves deciduous, leathery, lanceolate to ovate-lanceolate, up to 7 × 3 cm, sometimes more. Margin undulate, with up to 13 sharp teeth on each side. Green and glabrous above when mature, densely covered with silvery white hairs beneath, the midrib and lateral veins conspicuous. Petiole about 5 mm. Cup hemispherical, about 3 × 2 cm, acorns up to 2 cm long, mostly enclosed in the cup and ripening the second year. (Mucina & Dimopoulos 2000; Trigas & Zigiris 2009).
Distribution Greece Euboea (Evia)
Habitat Dry Pinus halepensis woodland on rocky soils from near sea level to 600 m, with Cotinus coggygria, Pistacia terebinthus, and Erica manipuliflora.
USDA Hardiness Zone 7
RHS Hardiness Rating H6
Conservation status Not evaluated (NE)
Taxonomic note Although recently treated as a subspecies of Q. trojana, Simeone et al. (2018) found that Quercus euboica appears genetically isolated from the former and recommended it be treated as a species. It differs from Q. trojana in its shrubby habit and leathery leaves white tomentose beneath.
This interesting species, only described in 1949, has a very resticted distribution and is rare in cultivation where it has proved to be very slow growing. Two plants are growing at the Botanical Garden of the Agricultural University of Athens (M. Papafotiou pers. comm. 2020). It was introduced to Sir Harold Hillier Gardens in 2006 when seed was sent from Euboea. It has reached 2.1 m tall at Thenford, England (D. Webster pers. comm. 2020) and two plants less than 1 m tall are at Arboretum des Pouyouleix, France (Béatrice Chassé pers. comm. 2020), with another small plant at Chevithorne Barton, England.
Kartsonas & Papafotiou (2009) developed a micropropagation technique for this species and recommended it as an ornamental plant and for reforestation due to its drought tolerance and ability to resprout after fire and grazing.
Though as yet Not Evaluated according to IUCN, Trigas and Zigras (2009) suggest it should be regarded as VU (Vulnerable). The images shown here are taken from their article in the Red Data Book of Rare and Threatened Plants of Greece.
The specific epithet derives from its occurrence on the island of Euboea (Evia or Evvia), Greece.
