Distribution, ecology and phenology

Abrahamia nitida occurs in humid forest in coastal eastern Madagascar ( Map 6 View Map 6 ). It has been recorded in flower in December and in fruit in late January.

Conservation status

With an EOO of 45,042 km 2, a minimum AOO of 76 km 2, and 14 known locations, with subpopulations in 4 protected areas (Agnalazaha, Makira, Nosy Mangabe, and Pointe à Lareée) and the remainder subjected to pressure from forest exploitation and land clearing, A. nitida is assigned a preliminary conservation status of “Near Threatened” [NT] using the IUCN Red List Categories and Criteria ( IUCN, 2012).


The leaves of A. nitida are usually whorled, a feature found in only a few other members of the genus, the most similar being A. sericea , from which A. nitida can be distinguished by its leaves with widely (vs very closely) spaced secondary veins, glabrous (vs pubescent) disk, and glabrous (vs velutinous) fruit.

We have followed René Capuron (note in herb.) in considering the second collection made by Thouars listed above as an isotype despite the fact that we cannot be certain it represents part of a single gathering.
