Roundleaf Sundew (Drosera rotundifolia) Linnaeus, 1753

 

Synonyms: Drosera corsica, Drosera septentrionalis, Rorella rotundifolia, Rossolis rotundifolia, Rossolis septentrionalis

 

 

Drosera rotundifolia is one of the most widespread sundew species, being found in most of northern and eastern North America, Greenland, northern Eurasia, Korea, Japan, but is also as far south as New Guinea. It grows in nutrient-poor environments such as sphagnum bogs, fens, swamps, wet sands, lake and stream margins, and seeps; 0-3,000 m. The plant is carnivorous, feeding on invertebrates attracted to the sticky sugary substance on the tips of red glandular hairs, densely covering the upper surface of basal leaves. The invertebrates become stack, and the plant uses enzymes to dissolve its catch. Drosera rotundifolia flowers from June through September.
