Caladenia applanata, commonly known as the broad-lipped 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 up to three flowers on a stem up to 50 cm (20 in) high. The flower colour may be red, cream, green or yellow and is distinguished by its broad, flattened, red-tipped labellum.
Description
Caladenia applanata is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf 9–20 cm (4–8 in) long and 4–10 mm (0.2–0.4 in) wide.[2][3][4]
The inflorescence is a raceme, 25–50 cm (10–20 in) high with up to three flowers, each flower 7–9 cm (3–4 in) long and 6–8 cm (2–3 in) wide. The dorsal sepal and the lateral sepals have club-like glands on their ends. The lateral sepals and petals spread widely and have red markings but the petals lack glands on their ends. The labellum may be red, cream, green or yellow with a red tip and is a broad and flattened. There are short teeth along its edge, extending to its tip and four or more rows of red calli along its centre. Flowering occurs between September and October.[2][3][4]
Taxonomy and naming
Caladenia applanata was first formally described by Stephen Hopper and Andrew Brown in 2001 from a specimen collected south-west of Denmark. The description was published in Nuytsia.[1] The specific epithet (applanata) is a Latin word meaning "flattened",[5] referring to the labellum of this species.[2]
There are two subspecies:
- Caladenia applanata subsp. applanata;[6]
- Caladenia applanata subsp. erubescens[7] which has pink flowers[2]
Distribution and habitat
Broad-lipped spider orchid occurs in coastal areas between Yallingup and Albany in the Jarrah Forest and Warren biogeographic regions[8] where it shallow soil over granite.[2][3][9]
Conservation
Caladenia applanata is as "Not Threatened" by the Western Australian Government Department of Parks and Wildlife.[8]
