Vascular – Exotic
Dicotyledonous Herbs other than Composites
Low growing herb with distinctive strap-like leaves with sticky red hairs, each growing from a central axis (like a dandelion), with tall flower stems (up to 30 cm tall) with a number of bright pink flowers arranged at the tip of the flower stalk, the oldest flowers near the base.
Only known from two sites in Waitakere District, Auckland.
Dune slack wetlands.
Rosette-forming perennial herb. Leaves bright green, petiolate with a linear ligulate lamina, 8-16 cm x 4-6 mm. Lamina clad in red stalked glandular hairs secreting a sticky mucilage to trap insects and other small invertebrates. Peduncles several per plant, up to 30 cm long, glandular hairy, inflorescence a cyme of many (6-30) rose-pink regular 5-petalled flowers 12-14 mm across. Fruit a capsule, with each scape capable of producing 1000-2000 seeds.
Superficially similar to the native sundews, with Drosera arcturi (a montane to subalpine bog species) also having strap-like leaves although these are usually reddish rather than green, with wider petioles with sheathing bases.
Late spring to summer
Summer to autumn
