About the fact sheet
The Large-club Spider-orchid is a native terrestrial orchid with a single short and narrow hairy leaf that is dull green with irregular red/purple blotching at the base. Flowering time is August to October. The flower stalk measures 15–28cm, and the flowers are about 5cm across. Flowers are green to yellowish green, with brown tipped club-shaped petal and sepal tips. The labellum, or lip, has green to yellow-green fringes and a dark maroon centre.
In 2001 the orchid genus Caladenia underwent taxonomic review that entailed the inclusion of C. macroclavia in a new genus, Arachnorchis.
