Drosera anglica

Higher Taxonomy
Family: DroseraceaeView Description 
Habit: Annual, perennial herb, [subshrub], carnivorous; roots weak. Leaf: generally basal rosette, often coiled in bud; blade with insect-catching hairs adaxially, hairs gland-tipped and sticky, [sensitive bristles]. Inflorescence: cyme, raceme-like, [flowers solitary]; flowers [1] few, on long peduncle. Flower: bisexual, radial; calyx lobes generally 5; petals generally 5, free or +- fused; stamens (4)5 [(10)20]; pistil 1, ovary superior, chamber 1, placentas generally 3(5), parietal, style generally 3(5), each generally 2-lobed. Fruit: capsule, loculicidal; valves generally 3(5). Seed: generally many, spindle-shaped.
Genera In Family: 3 genera (2 with 1 sp. each), 170+ species: temperate, tropics, especially Australia, South America, southern Africa; especially in bogs, swamps; some cultivated as novelties (Dionaea, Venus' fly-trap, of southeastern United States).

Genus: DroseraView DescriptionDichotomous Key

Common Name: SUNDEW
Habit: Annual, perennial herb, often +- brown or +- red. 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.
Etymology: (Greek: dewy) Note: 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.), northern 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. (northern 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.
Drosera anglica Huds.
Habit: Perennial herb. Leaf: blade 15--50 mm, 2--7 mm wide. Inflorescence: peduncle generally 1, 6--25 cm. Flower: calyx 4--6 mm, +- 1/3 fused; petals 8--12 mm, white; style lobes 2, <= 2/3 to base. Seed: 1--1.5 mm, longitudinally striate-netted. Chromosomes: 2n=40.
Ecology: Swamps, peatlands, often with Sphagnum; Elevation: 1300--2000 m. Bioregional Distribution: KR, CaR, n SNH (n of Lake Tahoe), s Wrn; Distribution Outside California: circumboreal. Flowering Time: Jun--Aug Note: Leaves often especially long in California (Barry Rice, pers. comm.). Sterile hybrids with Drosera rotundifolia, generally more clumped than Drosera anglica but distinguished only by fruit, may be called Drosera ×obovata Mert. & W.D.J. Koch.
Synonyms: Drosera longifolia L., nom. rej.
Unabridged Note: Drosera longifolia L. rejected as ambiguous.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
