Lectotypus (designated here): INDONESIA. Java: s.d., Pryon s.n. (G-PREL [G00800108]!).

Notes. – BURMAN (1768: 233) cited in the protologue a Pryon collection, a reference to his father’s Thesaurus Zeylanicus (1737: 98) and a plate (tab. 66, fig. 3) (Fig. 1).

Asingle specimen of Pryon is present in G-PREL (G00800108). HOVENKAMP & MIYAMOTO (2005: 308) and HOVENKAMP (2013a: 65) cited this specimen as type but failed to indicate the institution of deposit in 2005 and the term “ lectotype ” both in 2005 and 2013. Thus, none of these citations can be accepted as valid lectotypification (TURLAND et al., 2018: Art. 9.22, 9.23). The lectotypification is based here on the single specimen of original material present in G-PREL [G00800108].
