About the Problem of Differentiation Between the Oaks Quercus pubescens Willd. and Quercus virgiliana. (Ten.) Ten.     pdf     HR     EN 57
Summary: In the work the morphological differences between the related downy hairy oaks Quercus pubescens and Q. virgiliana are analyzed. They occupy large areas especially in the Adriatic littoral of the Republic of Croatia, but they develop sporadically in its hinterland, too. The said oaks can be differentiated from each other by the morphology of their leaf, cupule and bark, by the arrangement of flowers on a short fruit shoot as well as by the appearance of their cupule.
Q. pubescens has a leaf with 4–6 pairs of lateral lobes, and the petiole is 1–2 cm, maximum 3 cm, long. Its bark at the trunk base is shallowly longitudinally furrowed. All female flowers of the short, fruit shoot are sitting, placed terminally. All ripe acorns are sitting, placed terminally. The cupule covered with small, triangular scales arranged like tiles on a roof is smooth in appearance.
Q. virgiliana has a leaf with 3–4 (-5) pairs of lateral lobes, and the petiole is more than 3 cm long. Its bark at the trunk base is deeply furrowed, on the cross cut like a cogwheel. The female flowers are arranged on a more or less long rachis, not longer than 10 cm, in the form of an ear, and the ears can be arranged both terminally and laterally in leaf axils. In the ear there are often clusters of several flowers. One or several ripe acorns are on a more or less long stalk, usually 1–2 cm long. At the top or sidewise on the cupule the remnant of the rachis can often be noticed in the form of a curved, dry extension. The cupule scales are verrucously swollen or protuberated, making the entire cupule verrucously wrinkled.
In case of any deviation from the above parameters, as a rule the hybrids are involved.
