Calytrix angulata, commonly known as yellow starflower, is a species of flowering plant in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with linear to egg-shaped leaves and clusters of yellowish-cream coloured flowers with 30 to 40 yellow stamens in several rows.
Calytrix angulata is a shrub that typically grows to a height of, and has linear to egg-shaped leaves long, wide and sessile or on a petiole up to long. There no stipules. The flowers are arranged singly in leaf axils, the floral tube more or less spindle-shaped with 10 ribs and long. The sepals are joined at the base, long with an awn up to long. The petals are creamy-yellow, lance-shaped to narrowly elliptic, long and wide and there are about 30 to 40 yellow stamens in 3 rows. Flowering occurs between August to December or January.[1]
Calytrix angulata was first formally described in 1839 by John Lindley in his A Sketch of the Vegetation of the Swan River Colony.[2] [3] The specific epithet (angulata) means "angular", referring to the branchlets.[4]
Yellow starflower is commonly found on plains and slopes in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia, where it grows in sandy soils.
