It flowers between September and November, and has been collected in fruit in November and December. <b>Conservation status</b> With an EOO of 51,339 km 2, a minimum AOO of 40 km 2, and an estimated maximum AOO of less than 2,000 km 2, as well as 10 known locations, only 2 of which are situated within protected areas (Ankarafantsika and Bemaraha) with the remainder projected to be subjected to continuing decline in habitat quality due to a combination of fire and land clearing, <i>A. deflexa</i> is assigned a preliminary conservation status of “Vulnerable’’ [VU B 2 ab(iii)] using the IUCN Red List Categories and Criteria (IUCN, 2012). <b>Notes</b> <i>Abrahamia deflexa</i> can easily be distinguished from all its congeners by the combination the small, glabrous leaves with a long, thin petiole and glabrous fruits. Of the five collections cited in the protologue, we have selected <i>Perrier de la Bâthie 1627</i> as the lectotype because it is represented by three specimens, whereas one of the other syntypes <i>(Perrier de la Bâthie 1627bis)</i> comprises only a single sheet, another <i>(Humbert 5063</i> = <i>Humbert &amp; Swingle 5063</i> = <i>Service Forestier 50)</i> is a collection of <i>A. phillipsonii</i>, and the remaining two <i>(Humbert 11694ter</i> and <i>13850)</i> could not be located. <b>Additional material examined</b> MADAGASCAR.
