Populas tremula, Linn. European Aspen. Fig. 3127. Open-headed light-lvd. tree, becoming 50-60 ft. tall, but mostly small and of relatively slow growth, producing suckers: lvs. small and thin, round-oval, more or less whitened beneath when young, bordered with deep and rounded incurved teeth; lf.-stalks long, slender and flattened, giving a restless motion to the foliage: lf.- buds small: catkins small, with hairy scales and stigma deeply divided; stamens usually 6-8. Widely distributed in Eu. and Asia, in this country known chiefly in its grafted weeping form (var. pendula, Hort.). The eastern Asiatic and Chinese form is made var. Davidiana by Schneider: always a slender tree, rarely exceeding about 60 ft.: young lvs. reddish purple and handsome as they unfold: suckers freely: there is a pubescent form of this variety.—The drooping form of the European aspen is perhaps the best weeping tree amongst the poplars. The spray is light, airy, and fountain-like, quite unlike the more common weeping forms of the native P. grandidentata, which present a stiff angular form, a combination that is rarely pleasing. A characteristic feature of this tree is the profusion of its very long catkins that appear in earliest spring, even before our native poplars are in bloom. The staminate or male catkins are parti -cularly pleasing, and planters should choose that sex, if possible. Var. pyramidalis, Hort., is a slender pyramidalform. Var. Freynii, Herv. Lvs. rhombic in outline, cuneate at base, ciliate, pubescent beneath when young. France, Germany. Var. villosa, Wesm. Hairy on. young growths. Var. pseudograndidentata, Aschers. & Graebn., see description under No. 5. P. adenfipoda, Maxim. (P. tremula var. adenopoda, Burkill. P. Sil- vestrii, Pampan.), is a recent Cent. Chinese species (allied to P.tremula) not in the trade: lvs. long-stalked, broad-ovate, long-acuminate, serrate, soft-pubescent at least on young trees, those on old mature trees closely crenate, greenish beneath. It is growing at the Arnold Arboretum and in the Rochester parks, where it is doing well. CH The above text is from the Standard Cyclopedia of Horticulture.
