1. Family: Sapindaceae Juss.
    1. Genus: Xanthoceras Bunge
      1. Xanthoceras sorbifolium Bunge

        Xanthoceras sorbifolium was described by Joseph Hooker (Director of the Royal Botanic Gardens, Kew from 1865-1885) in 1887 as '…one of the most attractive and interesting hardy garden shrubs that has been introduced for many years'. It was originally collected near Beijing in about 1830 by the botanist Alexander von Bunge (1803-1890), when he was accompanying an overland mission to the capital from St Petersburg. It was brought into cultivation in Europe in 1868, when the botanist and missionary Père David (1826-1900) sent seeds and live plants to the Jardin des Plantes in Paris. David reported that although he had only seen wild plants in a small and mountainous area of China, the tree was well-known in Beijing and much cultivated by the Chinese, who ate the seeds.

    Description

    A deciduous, leafy bush or small tree growing up to 5 m tall and bearing reddish-brown branches. The leaves are glossy dark green on the upper side and paler below. The leaves are up to 30 cm long, held on a short petiole (leaf-stalk), borne alternately on the stem and are pinnate (divided into leaflets). The leaflets are narrow, 4-5 cm long and have serrated margins. The flowers appear in May or June (before the leaves) in sprays up to 25 cm long. Individual flowers are white, with streaks of greenish-yellow, turning to red at the base. The fruit is a round or pear-shaped capsule up to 6 cm long, revealing a spongy, white inner surface when it splits into three sections to release the seeds, which are round, purplish-brown and edible.
