Carpinus betulus
‘Frans Fontaine’
The leaf of the Hornbeam isa simple leaf that is oval and pointed. The leaf is quite long (7 - 12 cm) but has a relatively short leaf stalk or petiole. The leaf edge / margin is serrated / toothed, with many, small ‘teeth’ ..The leaf blade (lamina) is slightly corrugated / uneven as it is divided up by (ten - thirteen) pairs of ‘sunken’ veins. The underside of these veins may be hairy, as is the leaf stalk. The leaves are arranged alternately along the stems.In the Spring, the young stems and leaves (as they unfurl) may have a reddish tinge to them. In the Autumn, the leaves turn yellow / orange and may persist on the tree for some time.
Buds, Bark & Stem
Not unlike the buds of beech, hornbeam buds are long and slender but close to the stem. The bark is (silvery) grey, and may have vertical, ‘wriggly’ markings that vary in colour from silver to orange. At intervals, the bark may bear occasional wide but shallow fissures, and as the trunk ages it may develop criss-crossing ridges.
