Description

Caladenia radialis is a terrestrial, perennial, deciduous, herb with an underground tuber and which often forms clumps of up to ten plants after good rainfall. It has a single erect, hairy leaf, 50–180 mm (2–7 in) long and about 6 mm (0.2 in) wide. One or two red and cream-coloured flowers 40–50 mm (1.6–2.0 in) long and 40–80 mm (2–3 in) wide are borne on a stalk 150–350 mm (6–10 in) tall. The sepals and petals have long, brown, drooping thread-like tips. The dorsal sepal curves forward and is 25–45 mm (1–2 in) long and about 2 mm (0.08 in) wide. The lateral sepals and petals have about the same dimensions as the dorsal sepal although the lateral sepals are slightly wider. The labellum is 12–15 mm (0.5–0.6 in) long, 8–10 mm (0.3–0.4 in) wide and cream-coloured with red lines. The sides of the labellum sometimes have a few short teeth, the tip is curled under and there is a dense band of red or cream-coloured calli along the mid-line. Flowering occurs from August to early October.[2][3][4]

Taxonomy and naming

Caladenia radialis was first described in 1927 by Richard Rogers from a specimen collected near Dowerin and the description was published in Transactions and Proceedings of the Royal Society of South Australia.[1][5] The specific epithet (radialis) is derived from the Latin word radius meaning "ray", "rod" or "spoke",[6] referring to the radiating red lines on the labellum.[3]

Distribution and habitat

The drooping spider orchid is found between the Fitzgerald River National Park and Northampton in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest and Mallee biogeographic regions where it grows in a range of habitats including on granite outcrops and near the edges of salt lakes.[2][3][4][7]

Conservation

Caladenia radialis is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[7]

Caladenia radialis é uma espécie de orquídea, família Orchidaceae, endêmica do sudoeste da Austrália,[1] onde cresce isolada em grupos pequenos, ou grandes colônias, em bosques, áreas reflorestadas, ou de vegetação arbustiva e afloramentos de granito, em áreas de solo bem drenado mas ocasionalmente nas areias ao redor de lagos salgados e planícies sazonalmente alagadiças, com flores de sépalas e pétalas externamente pubescentes, muito estreitas, longas e agudas, esparramadas, que vagamente lembram uma teia de aranha. Seu labelo é cordado, largo, com calos eretos clavados. São plantas com uma única folha basal pubescente e uma inflorescência rija, fina e pubescente, com uma ou poucas flores, mas que em conjunto formam grupo vistoso e florífero.[2]
