Prasophyllum obovatum is a species of small terrestrial orchid endemic to New South Wales. It has a single leaf fused to the flowering stem and a few reddish-purple flowers with translucent patches.
Prasophyllum obovatum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single leaf sheathing the flowering stem at the base. A few reddish-purple flowers with translucent patches are arranged along a flowering stem up to high. The flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal and is broadly egg-shaped, about long, and forms a hood over the column. The lateral sepals are lance-shaped, about long, deeply concave with a tiny, down-curved point on the tip. The petals are broad and curved with two tiny points at the tip, one with a small gland. The labellum is egg-shaped with the narrower end towards the base, about long with a winged column.[1]
Prasophyllum obovatum was first formally described in 1948 by Herman Montague Rupp in The Victorian Naturalist from specimens collected at Heathcote in the same year.[2] The name is accepted at Plants of the World Online but is considered a synonym of Corunastylis rufa at the Australian Plant Census.[3]
Prasophyllum obovatum occurs in New South Wales.
