Nomenclatural notes.

Burret (1926) based Eleutherostylis renistipulata on two collections (syntypes) made by C.L. Ledermann in Sepik, Papua New Guinea: Ledermann 10535 with male flowers and Ledermann 10754 with female flowers and fruit. Neither of these syntypes, which were in Berlin (B), survived World War II (Juraj Paule, pers. comm.; see also Hiepko (1987)). Steenis-Kruseman (1950, Steenis-Kruseman 1958) noted that, in addition to Ledermann collections deposited in B, duplicate material sometimes can be found in E, K, L and SING, but no duplicates of the syntypes have been located in these Herbaria. Hence, the designation here of a neotype for the name (Fig. 2 ).

Kostermans (1969) used two different epithets in the original description of Grewia morotaiensis : “raorotaiensis” in the text and “morotaiensis” in the figure caption. These epithets have equal priority. Subsequently, Kostermans (1972) effectively made a choice between these competing epithets when he placed G. morotaiensis in synonymy under Eleutherostylis renistipulata (see Turland et al. (2018; Art. 11.5)).
