About Wahlenbergia capillaris (G.Lodd.) G.Don
Wahlenbergia capillaris (G.Lodd.) G.Don is a perennial herb with a thickened taproot. It produces a few to many thin, erect, branched stems that reach a height of around 50 cm (20 in). Its leaves may be arranged all along the stems, or only grow near the base of the plant. The leaves are linear, measuring 4–50 mm (0.16–2.0 in) long and 0.5–6 mm (0.020–0.24 in) wide, and often have a small number of teeth along their margins. The flowers are blue, arranged in cymes. Each flower has five sepals that are joined at the base, with narrow triangular lobes 2–6 mm (0.079–0.24 in) long. The petals are joined at the base to form a narrow bell-shaped tube 4–9 mm (0.16–0.35 in) long, with elliptic to egg-shaped lobes 6–15 mm (0.24–0.59 in) long and 2.5–6 mm (0.098–0.24 in) wide. The style is 4.5–9.5 mm (0.18–0.37 in) long, ending in three lobes. Flowering occurs mainly between October and March. The fruit is an oval or cone-shaped capsule 4–9 mm (0.16–0.35 in) long and 1.5–5 mm (0.059–0.20 in) wide. Wahlenbergia capillaris is widespread across all mainland states and territories of Australia, and is especially common in disturbed sites and along roadsides.
