Gnephosis trifida is a species of flowering plant in the family Asteraceae and is endemic to the south-west of Western Australia. It is an erect or ascending, often branched, annual herb with narrowly elliptic or lance-shaped leaves with the narrower end towards the base, compound heads of 30 to 100 yellow flowers, and oval, purplish cypselas.
Gnephosis trifida is a erect or ascending annual herb 3–7 cm (1.2–2.8 in) high and sometimes unbranched or often with major branches from the base or upper nodes, and covered with glandular hairs. Its leaves are narrowly elliptic or lance-shaped with the narrower end towards the base, 2–8 mm (0.079–0.315 in) long and 1–2 mm (0.039–0.079 in) wide and densely covered with scale-like glandular hairs. The pseudanthia are arranged in cylindrical to narrowly oblong compound heads of 30 to 100, 10–40 mm (0.39–1.57 in) long and 1–2 mm (0.039–0.079 in) wide with 2 bracts and one or two florets in each pseudanthium. The petals are yellow, forming a tapering tube and there are five stamens. The fruit is an oval, purplish cypsela, 0.3–0.4 mm (0.012–0.016 in) long and there is no pappus.[2]
