Notes: Notes This species was been tranferred to Pouteria monticola (K.Krause) H.J.Lam and this view was accepted by Pennington, T.D. (1991) The Genera of Sapotaceae (Royal Botanic Gardens Kew & New York Botanical Garden). However, it is here maintained within the genus Planchonella until the relationship between Pouteria and Planchonella is resolved.
