Woody climber. Leaflets 9-13, ovate to more or less oblong, silver-haired on both surfaces. Flowers to about 15 cm long, covered with downy hair. Flowers mostly white to pink. Fruit pod to about 20 cm long, velvet-hairy. Syn. W. venusta Rehder & E.H. Wils.
Valder (1995) states that this white Wisteria is that described as a new species, W. venusta, by Rehder and Wilson in 1916. It seems that they regarded the name W. brachybotrys as applying to a variant of W. floribunda. However, according to Valder, the illustrations given by Siebold and Zuccarini show the distinctive characters of W. brachybotrys, while their illustration of W. floribunda (as W. chinensis) shows differences in these important characters: thus the name W. brachybotrys should stand.
Leaves silvery-hairy on both surfaces.
