WISTARIA CHINENSIS (_syns W. sinensis, Glycine chinensis_, and _G. sinensis_).--Chinese Wistaria. China, 1816. This is the only species at all common in gardens, and by far the handsomest in cultivation. It justly ranks amongst the most beautiful of hardy climbing shrubs, and is invaluable as a wall plant, or for clothing the bare stems of sparsely foliaged trees. The purplish-lilac flowers are produced in long, drooping racemes in early summer. W. chinensis alba has pretty white flowers; W. chinensis flore-pleno has not proved very satisfactory, but when seen at its best, which is, however, but rarely, the double flowers are both beautiful and showy; W. chinensis variegata has badly variegated foliage; and W. chinensis macrobotrys is a plant of great beauty with very long racemes of pale lavender flowers, but they vary a good deal in colour, those of some plants being almost white. It is a very desirable variety, and one that when better known is sure to attract attention. W. FRUTESCENS (_syns Glycine frutescens_ and _Thyrsanthus frutescens_).--North America, 1724. This is a very handsome deciduous climbing species from North America. The flowers, which appear towards autumn, are bluish purple and fragrant, and borne in erect racemes. It is quite hardy and equally suitable with the Chinese species for using as a wall covering. W. frutescens magnifica is an improved form of the species. W. JAPONICA.--Japan. A bush-like species bearing white flowers, but it is rarely seen in cultivation. It is, however, quite hardy, and succeeds well in the bush state at Kew. W. MULTIJUGA.--Japan, 1874. Resembles somewhat our commonly-cultivated species, and has pale purple flowers arranged in long racemes. It is a very ornamental and desirable species, but the flowers are not borne in great quantity. The Wistarias are of simple culture, but succeed best in rather rich alluvial soil, and where protection from cold winds is provided. XANTHOCERAS. XANTHOCERAS SORBIFOLIA.--China, 1870. An extremely pretty flowered and handsome leaved shrub, but owing to its late introduction is not yet well known. So far it has proved itself perfectly hardy in this country, there being specimens at wide distances apart that have stood uninjured through our past severe winters.
