Streptoglossa adscendens, commonly known as desert daisy,[1] is a species of flowering plant in the family Asteraceae and grows in all mainland states of Australia with the exception of Victoria. It is a ground cover, upright or ascending perennial or annual herb with purple or pink flowers.
Streptoglossa adscendens is a short-lived, leafy, many branched perennial or prostrate herb to high with faintly aromatic, glandular leaves and upright stems covered in soft, thin hairs. The leaves are oblong to lance shaped, rarely spoon shaped, long, wide, narrowing gradually at the base, margins smooth or toothed and ending in a point. The flowers are borne on a short peduncle or almost sessile usually in clusters near the apex of leafy branches, consisting of 20-40 pink florets, involucre long, enclosed by a distinctive whorl of 3 or 4 leaves long, bracts purplish or green, smooth or with soft hairs. Flowering occurs from March to October and the fruit is dry, one-seeded, ribbed, long and densely covered with silky, flattened hairs.[2] [3] [4]
Streptoglossa adscendens was first described George Bentham in Flora Australiensis as Pterigeron adscendens. In 1981 Clyde Robert Dunlop changed the name to Streptoglossa adscendens and the description was published in Journal of the Adelaide Botanic Garden.[4] [5] The specific epithet (adscendens) means "ascending".[6]
Desert daisy grows in a variety of habitats including granite hills and the edges of salt lakes in rocky, clay soils in all Australian mainland states other than Victoria.[1]
