What is "planchonella"

Planchonella is a genus of flowering trees in the gutta-percha family, Sapotaceae. Named in honour of Jules Émile Planchon, it contains around 100 mainly tropical species, two of which reach South America and about 18 make it to Australia. It was described by Jean Baptiste Louis Pierre. The genus is included in the larger genus Pouteria by some authorities, hence species such as Planchonella queenslandica are also known as Pouteria queenslandica.
