About Caladenia arrecta Hopper & A.P.Br.
Caladenia arrecta is a terrestrial, perennial, deciduous herb that grows from an underground tuber. It produces a single erect, hairy leaf that is 10–30 cm (4–10 in) long and around 2 mm (0.08 in) wide. The inflorescence is a raceme that stands 12–35 cm (5–14 in) high and bears up to three flowers. Each flower is 5–8 cm (2–3 in) long and 3–5 cm (1–2 in) wide, with red, yellow, and green colouring. The dorsal sepal is held erect, while the lateral sepals have prominently club-shaped, glandular ends that point obliquely downwards. The petals are also club-shaped, but spread upwards. The labellum is red, with fringes of pointed calli, and two pairs of rows of deep red calli running along its centre. Flowering takes place between late July and mid-October. This species, commonly called the reaching spider orchid, is found in scattered locations between Esperance and Bindoon, in the Avon Wheatbelt, Esperance Plains, Jarrah Forest, Mallee, Swan Coastal Plain, and Warren biogeographic regions. It grows in a wide range of soil types and habitats.
