Inflorescence terminal, sometimes axillary, a panicle or thyrse, 5-10 cm long, the axes flattened, covered with yellowish, ferruginous strigose indument. Male and female flowers 5- or 6-merous; pedicel 0-0.3 mm long, strigose or pubescent; calyx lobes deltate or narrowly deltate, 1-1.2 3 1-1.5 mm, imbricate, rarely valvate, adaxial surface glabrous, abaxial surface pubescent or ferruginous, persistent on fruit; corolla lobes ovate, 2-3 3 1-1.8 mm, imbricate or quincuncial, adaxial surface glabrous, abaxial surface pubescent; stamens 5 or 6.

Vernacular names

“Ditimena’’, “Hazombarorana’’, “Rodrano’’ (Tanala), “Sandramy’’, “Sosoka’’, “Tsimalazo’’, “Varoa’’, “Vodihazo’’ (Tanala).

Distribution, ecology and phenology

Abrahamia sericea occurs in eastern humid domain forest, extending from coastal areas to the escarpment ( Map 8 View Map 8 ), where it can reach 800-1200 m elevation. It flowers from September through December, and sets fruit from December until May.

Conservation status

With an EOO of 178,062 km 2, a minimum AOO of 236 km 2, and 64 known localities, with subpopulations in numerous protected areas, A. sericea is assigned a preliminary conservation status of “Least Concern’’ [LC] using the IUCN Red List Categories and Criteria ( IUCN, 2012).


Abrahamia sericea and A. grandidieri are distinctive within the genus in having very closely spaced, parallel secondary veins, but A. sericea differs by the presence of indument on its disk and ovary, a character absent in A. grandidieri but shared with another species, A. thouvenotii , which, however, has very widely spaced, arcuate secondary veins.
