It flowers from September through December, and sets fruit from December until May. <b>Conservation status</b> 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, <i>A. sericea</i> is assigned a preliminary conservation status of “Least Concern’’ [LC] using the IUCN Red List Categories and Criteria (IUCN, 2012). <b>Notes</b> <i>Abrahamia sericea</i> and <i>A. grandidieri</i> are distinctive within the genus in having very closely spaced, parallel secondary veins, but <i>A. sericea</i> differs by the presence of indument on its disk and ovary, a character absent in <i>A. grandidieri</i> but shared with another species, <i>A. thouvenotii,</i> which, however, has very widely spaced, arcuate secondary veins. <b>Additional material examined</b> MADAGASCAR.
