About Caladenia toxochila Tate
Caladenia toxochila is a terrestrial, perennial, deciduous herb that grows from an underground tuber. It produces a single, sparsely hairy leaf that is 50–120 mm long and 10–15 mm wide. One or two flowers, each 15–20 mm wide, are borne on a stalk 80–200 mm high. The sepals and petals are yellowish-green with central red stripes. Sepals have thin, club-like glandular tips that are 1–7 mm long. The dorsal sepal is 15–25 mm long, 2–4 mm wide, and curves forward. The lateral sepals are similar in size to the dorsal sepal; they are nearly parallel to each other, turned downward, and almost touch the ovary. The petals are 12–20 mm long, 1.5–3 mm wide, and also turn downward near the ovary. The labellum is pale green, 10–12 mm long and wide, and has a dark red tip. The sides of the labellum have many rounded teeth up to 1 mm long, its tip is curled under, and there are four rows of crowded, fleshy, blackish, club-shaped calli up to 1 mm long along its mid-line. Flowering occurs in August and September. This species is related to Caladenia concinna from New South Wales, but differs by having darker-coloured flowers, shorter labellum teeth, and fewer rows of calli. Common name bow-lip spider orchid, this species is found in scattered locations in western Victoria and south-eastern South Australia, where it grows in woodland and mallee alongside grasses and shrubs.
