About Heliophila pusilla L.f.
Heliophila pusilla L.f. is a slender annual plant that grows up to 30 cm (12 in) tall. Its hairless stems are soft, and either wiry or flaccid. The leaves are thread-like or lance-shaped, with the widest part located near the tip. They measure 5–35 mm (0.20–1.38 in) long and 3–15 mm (0.12–0.59 in) wide. Flowering occurs between August and October, with flowers arranged in dense racemes. Flower colour ranges from white to mauve. The petals are 2 to 6 mm (0.079 to 0.236 in) long, and sometimes have basal appendages. This species has 3-12 ovules. The fruits are submoniliform in shape and 5–18 mm (0.20–0.71 in) long. Their bead-like structures are either continuous or connected by narrow waists. This species, commonly called dainty sunspurge, is native to the area between the Kouebokkeveld Mountains and De Hoop in South Africa, and has been introduced to Australia. It grows best in clay soils.
