Caladenia leptochila, commonly known s narrow-lipped spider-orchid or narrow-lipped caladenia, [2] is a species of flowering plant in the orchid family Orchidaceae and is endemic to South Australia. It is a ground orchid with a single slender, hairy leaf and one or two yellowish-green and reddish-brown flowers.
Caladenia leptochila is a terrestrial, perennial, deciduous herb with a single, densely hairy, narrowly lance-shaped leaf 40–140 mm (1.6–5.5 in) long. The plant is 150–450 mm (5.9–17.7 in) high with one or two yellowish-green and reddish-brown flowers with a dark red labellum. The dordal sepal is 25–30 mm (0.98–1.18 in) long and curved under, tapering to a fine, club-shaped point. The lateral sepals and petals are 35–65 mm (1.4–2.6 in) long with a central reddish-brown stripe. [2] [3]
Caladenia leptochila was first formally described in 1882 by Robert D. FitzGerald in The Gardeners' Chronicle from specimens collected on Mount Lofty. [4]
In 2008, Robyn Mary Barker and Robert John Bates transferred Arachnorchis leptochila subsp. dentata D.L.Jones to the genus Caladenia as Caladenia leptochila subsp. dentata in the Journal of the Adelaide Botanic Gardens , [5] and the name, and that of the autonym are accepted by the Australian Plant Census:
Subspecies dentata is found in the Flinders Ranges where it grows below shrubs on forest slopes at altitudes of 700–800 m (2,300–2,600 ft), and subsp. leptochila grows in clay or gravelly soils in shrubby forest in the Mount Lofty Ranges. The latter subspecies is thought to have been common in Victoria in the past but is now probably extinct in that state. [3] [8]
Eriochilus, commonly known as bunny orchids, is a genus of flowering plants in the orchid family, Orchidaceae that is endemic to Australia. Orchids in this genus are distinguished from those in the similar Caladenia by having a glabrous leaf and a densely woolly labellum. Species occur in south-west Western Australia, South Australia, Queensland, New South Wales, the Australian Capital Territory, Victoria, and Tasmania. Their common name alludes to their prominent ear-like lateral sepals.
Dendrobium tetragonum, commonly known as the tree spider orchid, is a variable species of epiphytic or lithophytic orchid endemic to eastern Australia. Tree spider orchids are unusual in having pendulous pseudobulbs that are thin and wiry near the base then expand into a fleshy, four-sided upper section before tapering at the tip. There are only a few thin but leathery leaves at the end of the pseudobulbs and up to five flowers on relatively short flowering stems. To allow for the variations in the species there are five subspecies and a variety, some with a unique common name.

It is a ground orchid which grows singly or in small groups, has a single dark green, hairy leaf and a single yellowish-green flower with red stripes. It is only known from a few sites and has been classified as Endangered.
Caladenia attingens, commonly known as mantis orchid, is a species of flowering plants in the orchid family Orchidaceae and are endemic to the south-west of Western Australia.

The subspecies differ in size, distribution and habitat.
