-- The term "aegilops" is very confused, as it has been given to several species:
_aegilops L. or Auctores (Boiss. or Lam.) = Q.ithaburensis subsp macrolepis
_aegilops Griseb. = Q.trojana
_aegilops Scop. = Q.cerris
_aegilops Mill. = Q.pubescens
so it is better to give up with it !

"Valonia oak"
15-20 m; crown elliptic; leaves flat or slightly wavy, subleathery ,6-15 x 2.5-6 cm, oval or elliptical ; semi-evregreen; densely hairy beneath, with stellate trichomes; greyish-green and glabrous above; apex
pointed, base subcordate; margin with 3-8 pairs of triangular, broad, spiny, often lobulate lobes; petiole tomentose 1.5-4 cm; acorn 2.5-4 cm long, 2-3 cm wide, enclosed 1/2 by deep, wooly, 3 cm in diameter cup, with scales thick, recurved outward; acorn maturing in 2 years; bark blackish, fissured, scaly; young twig pubescent; bud ovoid, obtuse, tomentose; hardy (to -18°C); all types of soils, prefers dry ones; withstands alkaline soils;
The Balkans; Greece; South Italy; SW Turkey; Syria; Lebanon; 600 to 1600 m;
This taxon is today (2010) considered as being a true species (= Q. macrolepis Kotschy)

--- Q.x look  Kotschy 1860 Eich. Eur. Orient. 21
= Q.aegilops subsp look (Kotschy) A.Camus 1934
= Q.brantii subsp look (Kotschy) Mouterde 1966
For Menitsky, it is a hybrid with Q.libani, in mountains. Closely related to Q.brantii, but with cupscales less recurved, cup covering almost all the fruit (with apex sunken), and petiole shorter; Syria; "lo-ok" is the local name of the species.

However, the recent genetic studies (2018) show that the assessment of this oak as a parent of Q. ithaburensis can be rejected. Additional investigations are required to evalutate if the features of Q. look justifie its exclusion from the genetically and morphologically variable Q. cerris.
