About Caladenia leptochila Fitzg.
Caladenia leptochila is a terrestrial, perennial, deciduous herb. It has a single, densely hairy, narrowly lance-shaped leaf that is 40 to 140 mm (1.6 to 5.5 in) long. The entire plant ranges from 150 to 450 mm (5.9 to 17.7 in) in height, and bears one or two yellowish-green and reddish-brown flowers with a dark red labellum. The dorsal sepal is 25 to 30 mm (0.98 to 1.18 in) long, curved downward, and tapers to a fine, club-shaped tip. The lateral sepals and petals are 35 to 65 mm (1.4 to 2.6 in) long, and each has a central reddish-brown stripe. For distribution and habitat, subspecies dentata occurs in the Flinders Ranges, where it grows below shrubs on forest slopes at altitudes between 700 and 800 m (2,300 to 2,600 ft). Subspecies leptochila grows in clay or gravelly soils in shrubby forest in the Mount Lofty Ranges. This subspecies is thought to have been common in Victoria in the past, but it is now probably extinct there.
