Calectasia intermedia, commonly known as blue tinsel-lily or eastern tinsel lily is a species of flowering plant in the family Dasypogonaceae, native to the border areas of western Victoria and south-eastern South Australia and flowering in early spring. It is the only member of the genus Calectasia that is not endemic to Western Australia.
Calectasia intermedia is a rhizomatous perennial herb growing to a height of about 65 cm (25.5 in) as an undershrub. The rhizome is about 50 cm (19.5 in) long, horizontal and buried about 7–10 cm (3–4 in) deep and there are no stilt roots. The stems have many side branches and bear leaves with few hairs. Each leaf is about 5.7–16.8 x 0.5–0.8 mm (0.2–0.7 x 0.02–0.03 in) and tapers to a short, sharp point on the end. The base of the petals (strictly tepals) form a tube 10.5–11.6 mm (0.41–0.46 in) long, while the outer parts spread outwards to form a blue, papery star-like pattern which does not fade with age. In the centre of the star are six yellow stamens forming a tube which turns orange-brown with age. The thin style extends beyond the stamens. Flowers appear from September to October.
Calectasia intermedia is one of eleven species in the genus Calectasia. It was formally described in 1856 by German botanist Otto Wilhelm Sonder, based on plant material collected by Ferdinand von Mueller in the Grampians in Victoria. The specific epithet (intermedia) is from the Latin intermedius "coming between", referring to its apparent intermediate appearance between C. cyanea and C. grandiflora, the only two other species recognised at the time.
