About Jacksonia thesioides A.Cunn. ex Benth.
Jacksonia thesioides A.Cunn. ex Benth. is an erect to prostrate shrub, with a coarse to slender growth form. It typically reaches 0.1–4 m (3.9 in – 13 ft 1.5 in) in height and 1–3 m (3 ft 3 in – 9 ft 10 in) in width. Its main branches are dull green, while the terminal branches are sharply pointed cladodes. The leaves of this species are reduced to dark brown, egg-shaped scales; these scales measure 0.8–1.6 mm (0.031–0.063 in) long, 0.4–1 mm (0.016–0.039 in) wide, and end in a sharply pointed tip. Flowers are arranged sparsely along the branches, and grow on pedicels 1.1–1.5 mm (0.043–0.059 in) long. Below the sepals are egg-shaped bracteoles that measure 0.7–1.0 mm (0.028–0.039 in) long and 0.2–0.6 mm (0.0079–0.0236 in) wide. The ribbed floral tube is 0.8–1.5 mm (0.031–0.059 in) long. The sepals are membranous; their upper lobes are 2.1–2.3 mm (0.083–0.091 in) long and 0.9–1.0 mm (0.035–0.039 in) wide, and are fused for a length of 1.1–1.9 mm (0.043–0.075 in). Flower petals range in color from hot pink to mauve. The standard petal measures 2.2–4.1 mm (0.087–0.161 in) long and 3–4.8 mm (0.12–0.19 in) deep, the wing petals are 3.5–4.0 mm (0.14–0.16 in) long, and the keel petal is 2.9–3.5 mm (0.11–0.14 in) long. The stamens have green filaments that are 1.3–3.1 mm (0.051–0.122 in) long. This species flowers year-round. Its fruit is a woody, elliptic, densely hairy pod that measures 4.0–5.5 mm (0.16–0.22 in) long and 1.8–2.7 mm (0.071–0.106 in) wide. This Jacksonia species grows in woodland with sandy soil developed over granite or sandstone. Its distribution covers north-eastern Queensland, extends south to Townsville, and also includes the Torres Strait Islands.
