Drosera filiformis Raf.
Droseraceae (Sundew Family)
Synonym(s): Drosera filiformis var. filiformis
USDA Symbol: DRFI
A carnivorous plant with lavender-rose flowers in a 1-sided, elongated cluster on a leafless stalk, curved at tip, rising from erect, thread-like, sticky, basal leaves.
This striking member of the sundew family is distinctive, with its stringy leaves covered with glistening droplets of sticky exudate. Insects trapped in the sticky hairs are digested by plant enzymes. Researchers have found that substantial quantities of protein from the insects end up in the storage roots, demonstrating the importance of this source of nutrients. The southern plants are larger than the northern and are considered by some authorities to be the separate species D. tracyi. The genus name derives from the Greek droseros (dewy) and refers to the sticky droplets on the leaves.
