Etymology
Derived from Greek, "Penta-" (πέντα) means "five" and "-nisia" may come from the word "nisos" (νῆσος), which means "island" or "land." The specific epithet is derived from Latin, "angusti-" coming from "angustus," meaning "narrow" or "tight" and "-folia" coming from "folium," which means "leaf," hence the "narrow-leaved" reference in this flower's common name.

Taxonomy
Synonyms include Diotocarpus angustifolius Hochst. and Pentanisia variabilis Harv. var. glaucescens Cruse ex Sond. The genus Diotocarpus was revised alongside other herbaceous Rubiaceae in 1952, having been considered a taxonomic synonym of Pentanisia.
