Ovary pedicellated, ovate, smooth. Stigmas sessile.( Willd. and Forbes .) A native of Dauphine, where, according to Willdenow ,it forms a shrub 5 ft. or 6 ft. high, with dark violet-coloured, shining branches;but, according to the experience of Mr. Forbes, in the Woburn salictum,it is a handsome upright-growing tree, attaining the height of 12 ft. or14 ft., with the preceding year’s branches of a greyish brown colour, andthe young twigs dark brown above, paler beneath, polished, and some-what angular, or striated, and very brittle. Introduced in 1818. Themale, as observed in the London Horticultural Society’s arboretum, m1835, is an elegant kind, noticeable early in spring for its plentiful blos-soms, and subsequently for its leaves, which are remarkably neat in theirfigure and serrature, and more or less peculiar as compared with those ofkindred kinds. The dark colour of the shoots of the preceding year oryears is also an ornamental feature. There are plants at Woburn Abbey ,Henfield, and Flitwick House.
