4.1.6. Macropsychanthus densiflorus (Huber) L.P. Queiroz & Snak comb. nov.
Basionym: Dioclea densiflora Huber, Bol. Mus. Goeldi Hist. Nat. Ethnogr. 5(2): 406-407. 1909. Type: Brazil, Pará, Oriximiná, Ducke s.n. MG 7903 (holotype: MG! [007903]; isotype: RB! [00174878]).
Note.
Huber (1909: 406-407) did not cite any specimen in the original description of Dioclea densiflora and, in the absence of a type, Maxwell (1969: 254-255) indicated the specimen Ducke s.n. RB 11744 (collected on 20 Dec 1919) as a neotype. However, in the introductory pages of his work, Huber (1909) stated that all species were described, based on specimens collected by A. Ducke from 1902 to 1907 and housed at the Museu Goeldi herbarium (MG). He also transcribed Ducke’s field notes showing that he collected in Oriximiná in December of 1906 ( Huber 1909: 301), which coincides with the date and locality of the specimen A. Ducke s.n. MG 7903. Thus, we are assuming that this specimen is the same one used by Huber (1909) when describing the new species and consider the material housed at MG as the holotype.
