It has been collected in flower in September and in fruit in December. <b>Conservation status</b> With an EOO of 28 km 2, an AOO of 12 km 2, and three known locations, 2 of which are situated within protected areas (Mandena and Petriky) whereas the third one is highly degraded and subjected to continued degradation from uncontrolled harvesting and possibly also fire leading to a projected decline in all 5 sub-criteria, <i>A. ellipticarpa</i> is assigned a preliminary conservation status of “Endangered’’ [EN B1ab(i,ii,iii,iv,v)+2ab (i,ii,iii,iv,v)] using the IUCN Red List Categories and Criteria (IUCN, 2012). <b>Notes</b> <i>Abrahamia ellipticarpa</i> is vegetatively similar to <i>A. oblongifolia</i> but can be distinguished by its fewer secondary veins (18-30 vs 35-40), impressed and barely visible (vs slightly raised and very visible) tertiary venation, and large fruits (3-3.5 <b>3</b> 1.5-1.8 vs 2 <b>3</b> 1 cm) with evident (vs obscure) longitudinal striations. <b>Paratypi</b> MADAGASCAR.
