Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary narrowly conical, the apex tapering into the style, c- 4 mm long in total, glabrous; style glabrous, persistent after the corolla has fallen, divided 4 – 7 mm above the ovary into unequal arms, one 2 – 3 mm long, the other 2.5 – 4.5 mm long; stigmas reniform, 0.25 mm in diam- Capsule and seeds not seen

Morphology General Habit
Scrambling undershrub reaching 1 m; stems woody, wiry in texture, reddish-brown, roughly and thinly pilose to subtomentose on young parts, the ultimate parts very thin
Morphology Reproductive morphology Flowers
Flowers in axillary, pedunculate, compound cymes with up to 20 flowers forming somewhat elongate lateral inflorescences c- 5 × 3 cm; bracts resembling leaves; peduncles 2 – 5 cm, somewhat woody, pubescent; pedicels 3 – 4 mm, thinly pubescent; bracteoles 1 – 3.5 × 0.2 – 0.5mm, filiform to linear-lanceolate, pubescent
Phenology
Found in flower in February and April so probably flowering in the second half of the summer rainy season from about January to April.
Note
This species is superficially similar to several others described from sect. Trichantha, which are all similar woody climbers having white flowers with distinctive brown midpetaline bands and hirsute seeds. Following Myint & Ward’s key (1968: 145ff.) Bonamiacerradoensis will key out near to B. balansae but is immediately distinguished by its more numerous flowers and leaves tomentose on the abaxial surface. It is probably closer to B. agrostopolis but it is easily distinguished by the near glabrous sepals and the clearly lateral inflorescences, which, in none of the specimens seen, show any tendency to become aggregated towards the branch tips. The somewhat elongate axillary inflorescences appear to be unique to this species.
