About Corybas fimbriatus (R.Br.) Rchb.f.
Corybas fimbriatus (R.Br.) Rchb.f. is a terrestrial, perennial, deciduous herb that produces a single broad, egg-shaped to round leaf, measuring 15–40 mm long and wide. The upper surface of the leaf is dark green, and the lower surface is silvery green. The plant bears a single dark reddish purple to crimson flower that has translucent patches. The dorsal sepal is 20–25 mm long and 15–18 mm wide, concave, and it partially forms a hood over the labellum. The lateral sepals are linear, around 5 mm long, and usually joined to one another. The petals are linear and approximately 4 mm long. The labellum is around 15 mm long, with a transparent central mound, and has many long, narrow teeth along its edges. Flowering of this species takes place from May to August. This species is widespread and common, growing in heath and moist forest. It occurs in Queensland south from Gympie, on the coast and ranges of New South Wales, in south-east Victoria, and in Tasmania. There is also an isolated population of this species located on the Atherton Tableland. Corybas fimbriatus is usually only cultivated by orchid enthusiasts, but it is easier to grow than other orchids in the same genus. It is grown in a free draining, sandy mix, and requires good air circulation with 50% sun.
