Description

Styphelia triflora is a spreading to bushy shrub which grows up to 0.4–2 m (1–7 ft) tall with mostly smooth branchlets. Its leaves are mostly elliptic to oblong-elliptic in shape, 14–33 mm (0.6–1 in) long, 3–8.5 mm (0.1–0.3 in) wide, edges usually smooth and ending in a sharp point on the tip. The flowers are tube-shaped, pendulous or spreading, mostly pink to red, sometimes light yellow-green or cream. The corolla is 13.5–29.4 mm (0.53–1.16 in) long forming a tube 12–14 mm (0.5–0.6 in) long. The five stamens are straight and extend prominently beyond the end of the petal tube, sepals 8.2–13.4 mm (0.32–0.53 in) long and smooth. The finely ribbed fruit are 6.5–8 mm (0.26–0.31 in) long. Flowering occurs mostly between April and October.[2][3]
