Spyridium daltonii is a species of flowering plant in the family Rhamnaceae and is endemic to Victoria in Australia. It is a shrub with softly-hairy branchlets, linear to narrowly elliptic leaves, and small groups of hairy, yellowish flowers.
Spyridium daltonii is a shrub that typically grows to a height of, its branchlets covered with a soft layer of star-shaped hairs. The leaves are linear to narrowly elliptic, mostly long and about wide with stipules long at the base. The edges of the leaves are rolled under, the tip is sharply-pointed, the upper surface is glabrous and the lower surface is covered with star-shaped hairs. The heads of flowers arranged on the ends of branches and in upper leaf axils and are up to about in diameter with bracts at the base, the individual flowers more or less sessile, yellowish and densely hairy. The sepals are long and the petals about long. Flowering occurs from August to October and the fruit is a capsule about long.[1]
This spyridium was first formally described in 1875 by Ferdinand von Mueller who gave it the name Trymalium daltonii in Fragmenta Phytographiae Australiae from specimens collected by St. Ely D'Alton.[2] [3] In 2006, Jürgen Kellermann changed the name to Spyridium daltonii in the journal Muelleria.[4] [5]
Spyridium daltonii grows in heathy woodland and is endemic to central areas of the Grampians in Victoria.
