84. Psychotria expansa Blume, Bijdr. 963. 1826.

Ξ Chassalia expansa (Blume) Miq., Fl. Ned. Ind. 2: 280. 1857 .

Lectotypus (designated by SOHMER, 1988: 320): INDONESIA. Java: “ ad pedem montis Salak, floret Majo ”, s.d., Blume s.n. (L [L-908-202-2]) .

Notes. – This name was accepted and said to be a species occurring from Borneo to Java and Sumatra by GOVAERTS et al. (2015). However this name was lectotypified and then placed in synonymy with another poorly known species, Psychotria montana Blume (discussed below), by SOHMER (1988). The treatment of this name by BEAMAN & ANDERSON (2004), who were followed by GOVAERTS et al. (2015), is confused because they simultaneously accepted the name P. expansa Blume and placed a combination based on this name, Chassalia expansa (Blume) Miq., in synonymy with a different species, P. malayana Jack. The status of P. expansa cannot be clarified until these various species are better understood.
