Ecology & Habitat

Description

Linear-leaved sundew is a small, perennial herb with leafless, glabrous stems that are 6-13 cm tall. The linear leaf blades are 2-5 cm long and approximately 2 mm wide. Petioles are flat and 3-7 cm long, while blades are covered with long, purple, gland-tipped hairs which trap insects. The 1-4 flowers are borne in a narrow, open inflorescence at the tip of the stem. The 5 egg-shaped, white petals are approximately 6 mm long, and the sepals are 4-5 mm long. The fruit is a small capsule with numerous seeds.

Diagnostic Characteristics

This species is very difficult to distinguish from the more common D. ANGLICA. The leaves of D. LINEARIS are more linear and the seeds are rounded on the ends rather than tapered to a point.

Habitat

Marl fens, wet, limey shores, often in a centimeter of water (Mellichamp in FNA (2015)).
