Caladenia oreophila is a plant in the orchid family Orchidaceae and is endemic to south-eastern Australia. It is a ground orchid with a single leaf and a single greenish-cream flower with pale red stripes a red labellum with a greenish-cream base.
Description
Caladenia oreophila is a terrestrial, perennial, deciduous, herb with a spherical underground tuber and a single leaf, 60–100 mm (2–4 in) long and 5–12 mm (0.2–0.5 in) wide. A single greenish-cream flower with pale red stripes is borne on a spike 120–200 mm (5–8 in) tall. The sepals have dark red, club-like glandular tips 2–5 mm (0.08–0.2 in) long and are 20–30 mm (0.8–1 in) long and 2–3 mm (0.08–0.1 in) wide whilst the petals are slightly shorter. The sepals and petals curve downwards, the petals more widely spreading than the sepals. The petals taper to a point and lack club-like tips. The labellum is reddish with a greenish-cream base, 11–13 mm (0.4–0.5 in) long and 7–8 mm (0.28–0.31 in) wide with the sides curved upwards and the tip curled under. The sides of the labellum have triangular teeth about 0.5 mm (0.02 in) long, decreasing in size towards the tip. There are four rows of calli about 1 mm (0.04 in) long near the base of the labellum and tapering towards the tip. Flowering occurs in September and October.
Taxonomy and naming
This orchid was first formally described in 2006 by David Jones and given the name Arachnorchis oreophila. The description was published in Australian Orchid Research. In 2007 Gary Backhouse changed the name to Caladenia oreophila. The specific epithet (oreophila) is derived from the Ancient Greek words oros meaning "mountain" or "hill" and philia meaning "friendly love" , "affection" or "fondness", referring to the habitat preference of this species.
Distribution and habitat
Caladenia oreophila is only known from the Cann River valley in Victoria, growing in tall forest with a sparse understorey. It probably also occurs on the Southern Tablelands of New South Wales.
Conservation
Caladenia oreophila is listed as "endangered" under the Victorian Flora and Fauna Guarantee Act 1988.
