''Erythrina × bidwillii'' is the scientific name for two different cultivars produced from hybridising ''Erythrina'' species at Camden Park Estate, New South Wales, Australia, in the early 1840s by William Macarthur, one of the most active and influential horticulturists in Australia. The two different cultivars resulted from two separate crossings of ''Erythrina herbacea'' L. (female) with ''Erythrina crista-galli'' L. (male): * ''Erythrina × bidwillii'' Lindl. 'Camdeni' * ''Erythrina × bidwillii'' Lindl. 'Blakei' Although the flowers of both cultivars are similar, the form of the plants is different — one is a small tree, while the other is a shrub. == Botanical description == Depending on the cultivar, they are either shrubs or small trees. Leaflets 5–10 cm long, generally ovate-elliptic as in ''Erythrina crista-galli'' and occasionally with a single prickle. Flowers to 5 cm long, in characteristic long, deep blood red clusters; standards about 4–5 cm long, relatively narrow, about 1–1.5 cm wide. Sepals in a bell-shaped slightly split tube, mostly as long as or slightly longer than wide. Stamens with upper half protruding from the keels in mature flowers.〔(''Horticultural Flora Of South Eastern Australia'' Volume 3, Part 2 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Erythrina × bidwillii」の詳細全文を読む スポンサード リンク
