Notes.

There are no nomenclature issues with E. amazonica , as the name was validly published and its type specimen was correctly cited (Fig. 1 ). However, all databases and studies of the genus state that the protologue was published in 1939. Still, according to the journal’s website, the publication date is October 1938.

Etymology.

The specific epithet " Erythrina amazonica " is derived from Latin, meaning "from the Amazon", and it was chosen due to the species being native to the Amazon Forest domain.

Vernacular names.

According to herbaria labels, E. amazonica is generally known as “mulungu” in Brazil, and also “açacurana” (and spelling variations) or “mulungu-de-espinho” in the state of Maranhão, and “açacurana” (and spelling variations) or “tento” in Pará.
