Drosera

Drosera is a genus of carnivorous plants, commonly called sundews, whose glandular leaves trap and digest small prey. Its species occur on every continent except Antarctica.

Glandular trichome: A hairlike plant structure with secretory cells that release substances onto its surface. Drosera leaves bear glandular trichomes that secrete the sticky droplets used to catch prey.
Tentacle (botany): A slender, mobile leaf outgrowth found in certain plants. Sundew tentacles carry the glands that produce adhesive droplets and often move during capture.
Dionaea muscipula: A carnivorous plant species commonly known as the Venus flytrap, with rapidly closing hinged leaves. Unlike the Venus flytrap's snap trap, Drosera generally captures prey with adhesive droplets.
Drosera capensis: A South African sundew species with long, strap-shaped leaves and mobile glandular tentacles. This commonly cultivated species clearly displays the curling response typical of many sundews.
Carl Linnaeus: A Swedish naturalist who established the binomial system of naming species. Linnaeus described Drosera species and gave the genus its place in formal plant taxonomy.
Plant carnivory: The capture and digestion of animals by plants to obtain mineral nutrients. Drosera is a prominent example of this broader nutritional strategy.
Plant gland: A plant structure specialized for producing or releasing substances. Sundew trapping depends on glands that secrete mucilage and digestive fluids.
Nepenthes: A genus of tropical pitcher plants that capture prey in fluid-filled leaves. Pitcher plants use pitfall traps rather than the sticky leaf surfaces characteristic of Drosera.
Drosera rotundifolia: A widespread sundew species with round leaves, found in bogs across northern regions. Its circumpolar distribution illustrates how Drosera occupies cold as well as tropical habitats.
Taxonomy: The science of naming, describing, and classifying organisms. Taxonomy organizes Drosera's many species and distinguishes the genus from related carnivorous plants.
