Waitzia acuminata, commonly known as orange immortelle, is an annual forb in the family Asteraceae. It is native to Australia. Plants grow to between 10 and 60 cm in height and have leaves that are long and narrow. These are between 2 and 7 cm long[2] and 2 to 5 mm in width.[3][4] The yellow, orange or white flowers appear between July and January.[3] Waitzia Acuminata occurs in all mainland states of Australia and is currently not considered rare or endangered. Its genus Waitzia is named after German botanist Karl Friedrich Waitz. Acuminata is a latin name describing things that are tapered to a point, named after the plants spindle like outer bracts.[5]
The species was first formally described in 1845 by German botanist Joachim Steetz in Plantae Preissianae.[1]
