Drosera, which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.
Drosera adelae, commonly known as the lance-leaved sundew, is a carnivorous plant in the genus Drosera that is endemic to Queensland, Australia.
Drosera monticola is a perennial carnivorous plant species in the genus Drosera, the sundews. This species is endemic to a single mountain range in Western Australia.
Drosera stolonifera, sometimes referred to as the leafy sundew, is a tuberous perennial species in the genus Drosera that is endemic to Western Australia. It produces 2 to 3 semi-erect lateral stems that grow 10 to 15 cm long. It is most closely related to D. purpurascens, but differs by several characteristics including height and petiole length. It is native to a number of swampy locations around Perth south to Pinjarra. It grows in peaty water-logged soils in swamp heathland and flowers from September to October. After a bushfire it will flower en masse.
Drosera dielsiana is a compact rosetted sundew native to South Africa, Eswatini (Swaziland), Mozambique, Malawi, and Zimbabwe. It was described as a new species by Arthur Wallis Exell and Jack Rodney Laundon in 1956. The diploid chromosome number is 2n=40. It was named in honor of Ludwig Diels, the author of the 1906 monograph on the Droseraceae.
Drosera bicolor is an erect perennial tuberous species in the genus Drosera that is endemic to Western Australia. It produces a basal rosette of leaves similar to that of D. peltata and the stem grows to 11 cm (4 in) high. Its white flowers that have a red spot near the petal base emerge from September to October. D. bicolor grows in deep silica sand on heathland along the upper Phillips River and south-east of Lake King.
Drosera gigantea, the giant sundew, is an erect perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows in sandy soils at the margins of swamps and near granite outcrops along the Western Australian coast from Albany north to just south of Geraldton. D. gigantea produces small shield-shaped leaves along many lateral branches that look like a small tree. Individual plants can grow up to 0.2–1 m (0.7–3.3 ft) tall. Because of its tall, tree-like form, it is considered one of the largest Drosera species. It is also easily cultivated and enjoys damp, humid conditions often provided in greenhouses. White flowers emerge from August to November. The red tubers of this species can grow to be 3.8 cm (1.5 in) in diameter and may be a metre below ground.
Drosera falconeri is a carnivorous plant in the family of Droseraceae. It is endemic to the Northern Territory of Australia.
Drosera fulva is a carnivorous plant in the genus Drosera and is endemic to the Northern Territory in Australia. Its semi-erect or prostrate leaves are arranged in a compact basal rosette. Oblanceolate petioles emerging from the center of the rosette are typically 2–3 mm wide at its widest. Red carnivorous leaves at the end of the petioles are small and round at 2–3 mm in diameter. Inflorescences are 25–45 cm (10–18 in) long with white or sometimes pink flowers being produced on 50-or-more-flowered racemes from February to May.
Drosera finlaysoniana is a species of sundew native to Australia, Hainan, Taiwan, the Philippines and Mainland Southeast Asia. Like other members of Drosera sect. Arachnopus it is an annual.
Drosera nivea is a species of carnivorous plant. It is a pygmy sundew and is native to Western Australia. The specific epithet nivea is derived from the Latin word niveus, meaning white, in reference to the colour of the plant's flower. It is closely related to Drosera citrina and has previously been considered a variety of D.citrina known as D. citrina var. nivea.
Drosera aquatica is a species of sundew endemic to the Northern Territory and Western Australia. It was first described by Allen Lowrie in 2013. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
Drosera aurantiaca is a species of sundew endemic to the Northern Territory and the north of Western Australia. It was first described by Allen Lowrie in his 2014 Carnivorous Plants of Australia Magnum Opus. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
Drosera barrettiorum is a species of sundew endemic to the north of Western Australia. It was first described by Allen Lowrie in his 2014 Carnivorous Plants of Australia Magnum Opus. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
Drosera cucullata is a species of sundew endemic to the north of Western Australia and the Northern Territory. It was first described by Allen Lowrie in his 2014 Carnivorous Plants of Australia Magnum Opus. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
Drosera fragrans is a species of sundew endemic to the north of Western Australia and the Northern Territory. It was first described by Allen Lowrie in his 2014 Carnivorous Plants of Australia Magnum Opus. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
Drosera glabriscapa is a species of sundew endemic in the Kimberley region of Western Australia. It was first described by Allen Lowrie in his 2014 Carnivorous Plants of Australia. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
Drosera nana is a species of sundew endemic to the north of Western Australia and the Northern Territory. It was first described by Allen Lowrie in his 2014 Carnivorous Plants of Australia Magnum Opus. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
Drosera serpens is a species of sundew native to southeast Asia and tropical northern Australia. It was first described by Planchon in 1848. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
