subsp dalechampii (Ten.) A.Camus 1936|
robur var. dalechampii (Ten.) Fiori & Paol. 1908
petraea var. dalechampii (Ten.) Cristur. 1972
sessileis var. aurea (Wierzb. ex Rochel) Schur 1857
|Range||Central and SE Europe to Austria and Sicily; 800-1300 m;|
|Leaves||resembles Q.petraea, but leaves are thinner, oblong lanceolate, more lobed (4-7 pairs of narrow, irregular, subacute lobes), base cordate; hairless above, pubescent beneath (less than in Q.pubescens); petiole glabrescent 1.5-3 cm;|
|Fruits||cup with diamond-shaped, warty, slightly hairy, greyish scales;|
Bark, twigs and
|twigs hairless; terminal buds often with persistent stipules;|
|Hardiness zone, habitat||prefers dry, rocky soils;|
this taxon is perhaps a hybrid with Q.petraea; it shows, like Q.pubescens,
buds often silky, leaves with tertiary veins and pubescence beneath; like Q.petraea,
it shows a long petiole, and mature leaves nearly glabrous;|
-- for Govaerts & Frodin, it is a true species.
-- for Menitsky (1974), it a synonym of Q.petraea subsp medwediewii, itself product of the introgression of genes of Q.pubescens into Q.petraea.
