Genoplesium tectum
Genoplesium tectum, commonly known as the Cardwell midge orchid, is a small terrestrial orchid endemic to a small area in north-eastern Queensland. It has a single thin leaf fused to the flowering stem and up to thirty light red flowers with a dark reddish-black, hairy labellum. Description. "Genoplesium tectum" is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf with a reddish base and long, fused to the flowering stem with the free part long. Between five and thirty flowers are well spaced along a flowering stem long, reaching to a  height . The flowers lean downwards, are light red, about long and wide. As with others in the genus, the flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal is broadly egg-shaped, about long, wide and light reddish with prominent reddish-black bands. The lateral sepals are linear to lance-shaped, about long, wide, have a small gland on their tips and spread widely apart from each other. The petals are narrow egg-shaped, about long and wide with dark reddish bands. The labellum is elliptic to egg-shaped with the  narrower end towards the base, about long, wide with its edges densely covered with short, purplish hairs. There is a dark reddish-black callus in the centre of the labellum and extending almost to its tip. Flowering occurs from November to March. Taxonomy and naming. "Genoplesium tectum" was first formally described in 1991 by David Jones and the description was published in "Australian Orchid Research". In 2002, David Jones and Mark Clements changed the name to "Corunastylis tecta" but the change is not accepted by the Australian Plant Census. The specific epithet ("tectum") is a Latin word meaning "covered", "concealed  or secret", referring to the dense vegetation usually concealing this orchid. Distribution and habitat. The Cardwell midge orchid grows with dense sedges and grass in woodland and is only known from an area south of Cardwell.
