(Greek eu, well, handsome, and ptelea, elm). Trochodendraceae. Ornamental woody subjects grown for their handsome foliage; also the red anthers of the precocious flowers are conspicuous in early spring.
Deciduous shrubs or small trees: winter-buds conspicuous, with imbricate dark brown scales: leaves alternate, slender-petioled, dentate: flowers before the leaves, in axillary clusters along last year's branches, perfect, without perianth; stamens many, with large oblong-linear, red anthers: carpels many, stipitate, oblique, with a decurrent stigma, developing after the stamens have dropped, growing into a small, slender-stalked obliquely winged 1-4-seeded nutlet. - Three species in Japan, Cent, and W.

They are graceful bushy trees resembling the linden in habit and foliage; the bright green leaves are very slender-stalked, and the tree is conspicuous in early spring from the bright red anthers of its flowers. E. polyandra has proved hardy at the Arnold Arboretum and possibly E. Franchetii is of the same hardiness. They seem to grow well in a loamy well-drained soil and prefer somewhat moist situations. Propagation is by seeds or by grafting on their own roots.
