Annual, perennial herb, often ± brown or ± red.Key to Drosera
Leaf: petiole long; adaxial blade hairs gland-tipped.
Inflorescence: raceme-like cyme.
Flower: sepals, petals, stamens generally 5; petals white, pink, or purple; styles, placentas, valves generally 3.
170+ species: range of family. (Greek: dewy) Insects and other organisms trapped by sticky fluid secreted by leaf glands are secured by leaf folding around them and digested by bacteria as well as additional leaf secretions (enzymes, ribonucleases), providing nutrition; many cultivated and/or non-native taxa, not all documented by specimens, persisting in NCo (Mendocino Co., including Drosera tracyi Macfarl.), n SNH (Plumas Co.) after reported, ill-advised plantings.
Unabridged note: Drosera aliciae Raym.-Hamet and Drosera capensis L. (NCo; Mendocino Co.), and Drosera × hybrida Macf. (n SNH; Plumas Co.), all documented by specimens, all persisting from reported, ill-advised plantings. Drosera binata Labill., Drosera burmanni Vahl, Drosera capillaris Poir., Drosera filiformis Raf., Drosera intermedia Hayne, Drosera nitidula Planch., Drosera occidentalis Morr., Drosera tracyi Macfarl., and Drosera slackii Cheek all have been reported in NCo (Mendocino Co.) from similar plantings, but are not documented by specimens.
Leaf: blade 3–12 mm, 4–20 mm wide, base ± cordate or not.
Inflorescence: peduncles 1–several, 5–35 cm.
