Material in flower has been collected between August and October, and fruits have been gathered in November and December.   Conservation status With an EOO of 69,556 km 2, a minimum AOO of 104 km 2, and 28 recorded localities, with subpopulations in at least 11 protected areas (Zahamena, Betampona, Ambalabe, Pic d’Ivohibe, Ranomafana, Analamazoatra, Makira, Nosy Mangabe, Masoala, Anjanaharibe-Sud, and Marojejy) that comprise about 22 locations,  A. lenticellatais assigned a preliminary conservation status of “Least Concern’’ [LC] using the IUCN Red List Categories and Criteria ( IUCN, 2012).   Notes Material attributable to this species was assigned by PERRIER DE LA BâTHIE (1944, 1946) to an invalidly published variety of  Protorhus ditimena(≡  Abrahamia ditimena). Despite an unquestionable similarity to that species,  A. lenticellataclearly warrants recognition at the species level, differing from  A. ditimenain having leaves with an apex that is almost always acuminate, sometimes shortly so (vs emarginate or retuse) and whose blades are chartaceous (vs coriaceous) in texture.    Paratypi   MADAGASCAR. Prov.
