Ulmus ×hollandica 'Hollandica'

Dutch Elm

Lower branches often with corky outgrowths. Young shoots and leaf stalks mostly hairless, occasionally sparsely soft hairy. Leaves large, ovate-elliptic, tapering fairly uniformly to the tip, mostly 8-11 cm long, 5-6.5 cm wide, dark green, smooth and glossy above (rarely slightly rough and then mostly when young) and tending to lie in flat planes; vein pairs mostly 12-18; the basal lobe may cover the leaf stalk but is not so pronounced as in U. glabra. Leaf stalks mostly 0.5-1 cm long, hair absent or sparse.

Strictly, the common name Dutch Elm refers to the clone U. הhollandica 'Hollandica' although in Australia it is applied to most U. הhollandica clones. The name alludes to the country where the tree was first cultivated. In Australia, however, the common name has been applied to U. הhollandica and most of its clones.

A clone with roundish leaves having short pointed tips and intergrading with large-leaved U. procera (see illustrations).

Vic: Box Hill (Central Plantation, Whitehorse Rd); Kew (Genezzano College, side of drive); South Yarra (Fawkner Park) Tas: Launceston (most of the public parks and gardens; Cataract Gorge Reserve commemorative tree planted 1884).
