[1] Padbruggea species are scrambling climbers, reaching heights of up to 25 m (82 ft).

The erect inflorescence is a panicle, 7–35 cm (3 in – 1 ft 2 in) long, usually terminal, sometimes leafy and sometimes emerging directly from the stem.

The individual flowers are 13–25 mm (0.5–1.0 in) long and have the general shape of members of the subfamily Faboideae.

[5] A 2019 molecular phylogenetic study placed the genus in an expanded tribe Wisterieae, in a clade with Austrocallerya and, more distantly, Wisteria.

[2] According to Kew:[1] Padbruggea species are native from south-central and southeast mainland China, through Indo-China (Laos, Malaya, Myanmar, Thailand and Vietnam) to Sumatra and Java.
