Caladenia leptochila subsp. leptochila |
Caladenia leptochila subsp. leptochila, commonly known as the narrow-lipped spider orchid, [2] is a plant in the orchid family Orchidaceae and is endemic to South Australia. It has a single leaf and one or two yellowish or red flowers. It differs from subspecies leptochila in the colour of its flowers, lack of toothed edges to its labellum, and its distribution.
Caladenia leptochila subsp. leptochila is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect leaf, 100–200 mm (4–8 in) long and 8–12 mm (0.3–0.5 in) wide. One or two yellowish or red flowers 25–35 mm (0.98–1.4 in) in diameter are borne on a stalk 200–450 mm (8–20 in) tall. The sepals have thin, reddish, club-like glandular tips 5–8 mm (0.2–0.3 in) long. The dorsal sepal is erect, 40–65 mm (2–3 in) long and about 4 mm (0.2 in) wide. The lateral sepals are about the same size as the dorsal sepal but are turned stiffly upwards. The petals are 35–45 mm (1.4–1.8 in) long and about 3 mm (0.1 in) wide and spread horizontally or turn upwards. The labellum is 12–15 mm (0.5–0.6 in) long and 5–7 mm (0.2–0.3 in) wide and red with the tip rolled under. The sides of the labellum lack the teeth of subspecies dentata but there are four rows of short, red calli along its mid-line. Flowering occurs from September to November. [2]
Caladenia leptochila was first formally described by Robert FitzGerald in 1882 and the description was published in The Gardener's Chronicle from a specimen collected on Mount Lofty. [3] [4] In 2008 a new subspecies (Caladenia leptochila subsp. dentata) was described, with the result that Caladenia leptochila subsp. leptochila became an autonym. [1] [5] The specific epithet (leptochila) is derived from the ancient Greek words leptos (λεπτός) meaning "fine", "small" or "thin" and cheilos (χεῖλος) meaning "lip". [6]
The narrow-lipped spider orchid occurs in the south-east of South Australia where it grows in clay or gravelly soils in shrubby forest in the Mount Lofty ranges. [2] It is thought to have been common in Victoria in the past but is now probably extinct. [7]
Caladenia attingens, commonly known as mantis orchids, are plants in the orchid family Orchidaceae and are endemic to the south-west of Western Australia. There are three subspecies, each of which has a single hairy leaf and one or two brightly coloured flowers with upswept sepals and a labellum with long, comb-like fringes. The subspecies differ in size, distribution and habitat.
Caladenia denticulata subsp. denticulata, commonly known as the yellow spider orchid, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single erect, hairy leaf and one or two yellowish flowers which have a white labellum with pale red markings.

It has a single, hairy leaf and up to three lemon-yellow flowers with brownish-fawn spots on some parts. It mainly occurs in near-coastal areas north of Geraldton.
Caladenia leptochila subsp. dentata, commonly known as the toothed spider orchid, narrow-lipped spider-orchid or narrow-lipped caladenia, is a plant in the orchid family Orchidaceae and is endemic to South Australia. It has a single leaf and one or two mostly reddish-brown flowers. It differs from subspecies leptochila in the colour of its flowers, toothed edges to its labellum, and its distribution.
