[1] Hybanthus floribundus was first described as Pigea floribunda in 1838 by John Lindley,[2][3] but was transferred to the genus, Hybanthus in 1876 by Ferdinand von Mueller.

[2][4] This taxon name is accepted by most Australian authorities,[5][6][2] but not by Plants of the World Online[7] nor VicFlora[8] (both of which authorities consider Pigea floribunda as the accepted name).

It is a perennial shrub, growing from 15 cm to 2 m high.

[9] There are four subspecies, three of which have a restricted distribution in Western Australia, while the other is widespread.

[1] In Western Australia, it is found in the IBRA regions: Avon Wheatbelt, Coolgardie, Esperance Plains, Geraldton Sandplains, Great Victoria Desert, Jarrah Forest, Mallee, Murchison, Swan Coastal Plain, and Yalgoo.
