Inflorescence axillary or terminal, a panicle, 3-5 cm long, the axes terete or flattened, with ferruginous indument. Male and female flowers 5-merous (rarely 6-merous); pedicel 0-0.5 mm long, ferruginous pubescent or strigose; calyx lobes ovate, c. 1 3 1 mm, imbricate, adaxial surface glabrous, abaxial surface pubescent or ferruginous pubescent; corolla lobes ovate, 2 3 1 mm, imbricate, adaxial surface glabrous, abaxial surface ferruginous pubescent or scabrous; stamens 5 or 6. Male flowers with filaments 1-1.5 mm long, glabrous, anthers c. 0.5 mm long, subglobose, glabrous; disk cupuliform, sometimes shallowly so, 1-1.5 mm in diam., glabrous; ovary rudimentary. Female flowers with filaments 0.5-0.7 mm long, glabrous, anthers c. 0.3 mm long, subglobose to slightly ovoid, glabrous; disk annular, cupuliform, sometimes shallowly so, 1.5 mm in diam., sterile, glabrous; ovary very widely ovoid, slightly asymmetric, 1 3 1 mm, glabrous, placentation apical; style simple, very short, inserted more sub-apically than laterally, 1 mm long, glabrous, stigma capitate, 3-4-lobed.

Distribution, ecology and phenology Abrahamia oblongifolia occurs in far northern and northwestern Madagascar (Map 6), from sea level to an elevation of c. 300 m, usually along rivers or at the base of hills or mountains. Flowering material has been recorded in October and November, and fruits have been collected in December and January.
