Notes: Notes Previously known as Planchonella obovoidea H.J.Lam. Although Jessup, L.W. Austrobaileya, 6: 163 (2001) reduced the former species to the synonymy of Pouteria myrsinodendron (F.Muell.) Jessup, the epithet 'myrsinodendron' has not been applied within the genus Planchonella. This species was orginally described as Chrysophyllum myrsinodendron F.Muell., Fragmenta 6: 178 (1868). Therefore, the name Pouteria myrsinodendron is used here until the relationship between Pouteria and Planchonella is resolved. Jessup (pers. comm. 2006) suggests that this taxon probably belongs to the genus Planchonella.
