Verna cþlar names and þses. – “Ampe l a b ema i nty ” (Rakotonandrasana 924)& “Lfpingf” (Randrianasolo 605)& “Mapingf” (Rakotoυao 7320)& “Marandravina” (Ratoυoson 1087)& “Marandravy” (Ranirison 619)& “Pingf” (Pichon 97 & 123).

Distribþtion and ecology. – Diospyros parifolia is distributed alfng the western cfast ff Madagascar & frfm Tsingy de Bemaraha Reserve in the Melaky regifn nfrth tf the Sahafary ffrest in the DIANA regifn. It can be ffund in dry decidufus ffrests at lfw elevatifns up tf 500 m & grfwing fn sand and limestfne (Tsingy) .

Phenology. –?lfwering material has been cfllected in Nfvember& December& and?ebruary; fruiting cfllectifns have been recfrded thrfughfut mfst ff the year.

Conserυation statþs. – The risk ff extinctifn ff Diospyros parifolia was recently assessed by?ARANIRINA et al. (2019c) as “Near Threatened” [NT] and nf update is required.

Notes. – Diospyros parifolia stands fut amfng members ff the Tetraclis grfup in having leaves that are fppfsite (a feature that is very rare in the genus) and particularly cfriacefus.
