Schiedea stellarioides, a member of the pink family (Caryophyllaceae), is a slightly erect to prostrate sub-shrub 0.3 to 0.6 m (1.0 to 2.0 ft) tall with branched stems and internodes generally 3.5 to 6.5 cm (1.4 to 2.5 in) long. The opposite leaves are very slender to oblong-elliptic, 2.7 to 8.2 cm (1.1 to 3.2 in) long, 0.2 to 1.3 cm (0.1 to 0.5 in) wide, and one-veined. The perfect flowers lack petals and occur in open branched clusters. The inflorescence ranges from 15.0 to 32.0 cm (6.0 to 12.6 in) long. The flower stalks are 7.0 to 10.0 mm (0.28 to 0.4 in) long and the narrowly egg-shaped sepals are 2.9 to 3.3 mm (0.11 to 0.13 in) long. The flowers contain 10 stamens, three styles, and a two-lobed nectary. The capsular fruits are 2.2 to 3.4 mm (0.09 to 0.13 in) long and contain tiny, dark brown, circular to kidney-shaped, slightly wrinkled seeds.
