Type.

Adinobotrys Dunn, Bull. Misc. Inform. 1911: 194. 1911.

Diagnosis and note.

Compared to the tribe Wisterieae , the monogeneric Adinobotryeae comprises four species of evergreen trees (vs. lianas in tribe Wisterieae ). The species are: A. atropurpureus (Wall.) Dunn, A. katinganensis (Adema) J.Compton & Schrire, A. sarawakensis (Adema) J.Compton & Schrire and A. vastus (Kosterm.) J.Compton & Schrire. See the detailed description of Adinobotrys in Compton et al. (2019: 49) and a diagnostic key to the species and full list of synonymy in Compton and Schrire (2020).

Description.

Evergreen trees, up to 20 m in height. Stipules triangular, persistent. Stipels absent. Leaves 5-9 (-11) foliolate; rachis 11-33 cm long; leaflets 5-21 × 2-11 cm, coriaceous, ovate, elliptic to obovate, glabrous, apex acuminate, base obtuse to cordate. Inflorescence a terminal panicle 10-40 cm long; bracts 2-4 mm long, ovate; peduncle sparsely hairy to tomentose. Flowers 14-20 mm long; bracteoles at base of calyx tube, persistent, ovate; pedicels densely pubescent. Calyx narrowly campanulate, oblique, green, puberulent, five lobes acute to obtuse. Standard 11-20 × 13-20 mm, broadly ovate, apex acute, outer surface glabrous, inner surface pink to reddish-purple, rarely white, nectar guide yellow, with callosities; wings 12-19 × 5-8 mm, glabrous; keel ± equal to wings in length, glabrous, apex acute to rounded. Stamens diadelphous, vexillary filament free from other nine, all curved upwards at apex. Ovary hairy; style glabrous. Pods 7-25 × 3-6 cm, dehiscent, inflated or compressed, irregularly ovate to oblong or narrowly elliptic, surface glabrous, rugose, subseptate. Seeds 1-4 per pod, ovoid to oblong or flattened-orbicular, 15-38 mm long.

Distribution and habitat.

Evergreen forests in Brunei, Cambodia, India, Indonesia (Java, Kalimantan and Sumatra), Laos, Malaysia (Peninsula and Sabah), Myanmar, Thailand and Vietnam, below 1200 m in altitude.
