Description

Genoplesium mucronatum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single leaf sheathing the flowering stem. Between six and twelve green and reddish-purple flowers are arranged along a flowering stem up to 120 mm (4.7 in) high. The flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal forms a hood over the column and is about 2 mm (0.079 in) long, the lateral sepals are linear, about 3 mm (0.12 in) long and spread widely apart with a club-shaped gland at the tip and swollen at the base. The petals are triangular to lance-shaped, scarcely 2 mm (0.079 in) long with a pointed or tapering tip. The labellum is about 3 mm (0.12 in) long with a winged column. [2]

Taxonomy and naming

This species of orchid was first formally described in 1948 by Herman Montague Rupp, who gave it the name Prasophyllum mucronatum in The Victorian Naturalist from specimens collected at Woodford in the same year. [2] [3] In 2022, Matthew Renner changed the name to Genoplesium mucronatum in the journal Telopea [4] and the name is accepted by Plants of the World Online. [1] The name (as Prasophyllum mucronatum or Corunastylis mucronatum) is listed as a synonym of Genoplesium rufum at the National Herbarium of New South Wales [5] and the Australian Plant Name Index. [6]

Distribution and habitat

Genoplesium mucronatum occurs in eastern New South Wales. [1]

<i>Genoplesium</i> Genus of orchids

Genoplesium commonly known as midge orchids, is a genus of about 50 species of flowering plants in the orchid family, Orchidaceae and is found in Australia, New Zealand and New Caledonia. Midge orchids are terrestrial herbs with a single leaf at the base of the plant. They are similar to orchids in the genus Prasophyllum in that plants without flowers have a hollow, onion-like leaf. The flowers are small but often scented and attractive to their insect pollinators. There is disagreement about which species belong to this genus and some taxonomists suggest that most belong in the genus Corunastylis.
