About Cheiranthera alternifolia E.M.Benn.
Cheiranthera alternifolia E.M.Benn. is a small, scrambling, perennial understory shrub that grows up to 50 cm (20 in) tall, with smooth stems. Its leaves are linear, 7–60 mm (0.28–2.36 in) long and 0.75–1.5 mm (0.030–0.059 in) wide, arranged alternately, usually evenly spaced along the stems, with rolled-under margins. Flowers can grow singly or in clusters of 2 to 11, borne on 17–55 mm (0.67–2.17 in) long peduncles and 4–25 mm (0.16–0.98 in) long pedicels, and each flower has five yellow stamens. The petals are lanceolate, 4–8 mm (0.16–0.31 in) long and 5–8 mm (0.20–0.31 in) wide, and range in color from pale to deep bluish-purple. The flattened fruit capsules are roughly oblong to egg-shaped, and 12–18 mm (0.47–0.71 in) long. This species flowers from October to November. Commonly called finger-flower, Cheiranthera alternifolia is a common endemic species restricted to southern regions of South Australia, occurring from the southern Eyre Peninsula to the state's south-east and Kangaroo Island. While it previously occurred in Victoria, it is now presumed extinct there.
