Taxonomy and naming
Calothamnus cupularis was first formally described in 2010 by Alex George from a specimen found in the Kalbarri National Park.[2][3] The specific epithet (cupularis) is from the Latin word cupula meaning "a small tub" or "a cask"[4] referring to the shape of the fruits of this species.[2]
Distribution and habitat
Calothamnus cupularis occurs in a small area in the Kalbarri National Park,[2] in the Geraldton Sandplains biogeographic region[5] where it grows in sand in kwongan.[2]
Conservation
Calothamnus cupularis is classified as "priority 2" by the Western Australian government Department of Parks and Wildlife[5] meaning that is poorly known and from one or a few locations.[6]
