Eucalyptus – from Greek, eu, “well” or “true” and calyptus, referring to the calyptra (καλύπτρo) or operculum, which is a bud cap or covering which covers the developing flowers. The calyptra is a fusion of petals and/or sepals and is shed when the flower opens, leaving a flower with many stamens (staminate) surrounding one female part (carpel).

curtisii – honours Densil Curtis (1893-1973) who was a farmer, naturalist and bushman, who collected the type specimen. The species was named in 1931 from material collected in sandstone hills near Plunkett (hence the common name), 53 kilometres southwest of Brisbane, Queensland. 

This species is listed as “near threatened” under Queensland legislation.
