Discussion

Drosera brevifolia is the smallest and perhaps the most widespread species of the genus in the Southeast. It may be rare or local throughout its range, and may act as an annual, especially if the habitat dries out. The flowers are large for the size of the plant, and the stipitate-glandular scapes, pedicels, and sepals are quite distinctive. The species is easy to grow in cultivation.
