Thread-leaf Sundew
(Tracy's Sundew - Giant Threadleaf Sundew)
Drosera tracyi - MacFarland
Droseraceae (Sundew) Family

Plant is an upright, glandular perennial. Its preferred habitat is savannas and bogs or damp ditches. Distribution is coastal in the Escambia region.

The leaves are mostly basal; thread-like and glandular (sticky).

Flowers are on leafless stems and spiraled; bisexual; symmetrical in form; one-sided on the stalk; five sepals and five petals; pink to light purple. Flowers occur in the spring.

Fruit is a drooping capsule.

This member of the Sundew family is distinctive, with its stringy leaves covered with glistening droplets of sticky exudate. Insects trapped in the hairs are digested by plant enzymes. Researchers have fed these plants fruit flies labeled with the radioactive isotrope nitrogen-15 and have found that substantial quantities of protein from the insects end up in the storage roots, thus demonstrating the importance of this source of nutrients. The southern species is larger than the northern species and is considered by some authorities to be an altogether separate entity.
