Millettia Sect. Nothomillettia Miq., Fl. Ned. Ind., Eerste Bijv. 2: 301 (1861) ≡ Millettia subgen. Nothomillettia (Miq.) Kurz, J. Asiat. Soc. Bengal, Pt. 2, Nat. Hist. 45(2): 273 (1876).

Diagnosis.

Adinobotrys comprises two species of evergreen trees (vs. lianes in Tribe Wisterieae ). The bracteoles are persistent (caducous in Callerya s.str.), the calyx is oblique in both species, the standard is glabrous (sericeous in Callerya s.str.) and the wing petals are ± equal to the keel in length (vs. much shorter than the keel in Callerya s.str.).

Type species.

Adinobotrys atropurpureus (Wall.) Dunn ≡ Pongamia atropurpurea Wall.

Genus description.

Large spreading evergreen trees to 20 m or more in height. Stems green when young, terete, finely brown pubescent becoming brown and glabrous with age. Leaves with 5-9 (- 11) leaflets, evergreen, coriaceous and nitent when mature, imparipinnate, rachis 11-33 cm long. Stipules 2-4 mm long, deltoid, persistent. Stipels absent. Leaflets 5-21 × 2-11 cm, ovate, elliptic or obovate, glabrous above and below, upper surface nited, apex acute to acuminate, margins entire, base obtuse or cordate. Inflorescence a robust many-flowered erect terminal panicle 10-40 cm long, peduncle sparsely hairy to tomentose. Flowers 14-20 mm long, emerging from February to May (in A. atropurpureus ) and May to November (in A. vastus ). Floral bracts 2-4 mm long, persistent (caducous in A. vastus ), ovate. Bracteoles 1-2 mm long, at base of calyx tube, persistent, ovate. Pedicels 2-6 mm long, densely pubescent. Calyx narrowly campanulate, oblique, green, tube 4-6 × 6 mm, puberulent externally, five lobed, lobes unequal 0.5 mm long, acute or obtuse. Standard 11-20 × 13-20 mm broadly ovate, inner surface pink, dark reddish-purple, rarely white, nectar guide yellow, back of standard glabrous, apex acute, callosities of boss type. Wing petals 12-19 × 5-8 mm, glabrous, ± equal or longer than keel in length, each broadly semi-pandurate with basal claws 3-5 mm long. Keel petals 12-18 × 9 mm, glabrous, apex acute to rounded. Stamens diadelphous, nine fused together, the vexillary one free, all curved upwards at apex. Ovary sparsely to densely hairy, style glabrous, 5-6 mm long curved upwards at apex, stigma punctate. Pods 7-25 × 3-6 cm, inflated or flat ( A. vastus ), irregularly ovate to oblong or narrowly elliptic, dehiscent, surface glabrous, finely rugose, subseptate. Seeds 1-4, irregularly ovoid to oblong or flattened orbicular, sometimes laterally compressed inside the pod, 15-38 × 20-35 × 3-26 mm, hilum 2-3 × 2 mm, ovate-elliptic or circular.

Etymology.

adino - botrys = congested - bunch (Gk) referring to the congested inflorescence.
