Notes: Notes Pennington, T.D. (1991) The Genera of Sapotaceae (Royal Botanic Gardens Kew & New York Botanical Garden) transferred all species of Planchonella to the genus Pouteria. Therefore, he regarded this species as Pouteria torricellensis; however, it is here retained in the genus Planchonella until the results of further molecular work resolve the taxonomic status of these two genera.
