Type material.

Brazil. Rio de Janeiro: "Guanabara, Horto Experimental do Aterro Glória-Flamengo; Culta de sementes recebidas de Bureau of Plant Introduction (U.S.A.). Cresceu no Horto do Museu Nacional e depois foi transplantada para o Aterro da Glória”, 26 August 1963, Mello Filho 2025 (holotype: R [R000117879, two sheets]; isotype: NY [NY00007994]).

Notes.

There are no nomenclature issues with E. x fluminensis , as the name was validly published, and the type specimen was correctly cited (Fig. 12 ). The species is a hybrid between E. fusca Lour. and E. speciosa Andrews (Guedes-Oliveira et al. manuscript in preparation).

Etymology.

The specific epithet " Erythrina fluminensis " was based on the Portuguese word “fluminense”, which is derived from Latin meaning "inhabitant of river". It was presumably chosen as a homage to the denomination of people born in the state of Rio de Janeiro, Brazil, where the hybrid species was first cultivated in the country and still exists to the day of this publication.

Vernacular names.

There are no other known vernacular names for E. x fluminensis in Brazil besides the commonly used “mulungu”.
