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 hartmeyerorum is a summer-growing annual sundew that is native to the north of Western Australia. It was discovered in 1995 by Siegfried and Irmgard Hartmeyer. Drosera hartmeyerorum has long scrambling leaves which readily curl around any unfortunate insect that lands on the leaves. One major thing that separates this sundew from others are the round yellow trichomes at the base of the leaves. The function of the yellow trichomes is uncertain. Like most sundews, it grows in warm wet, sandy, peaty areas with high humidity and low nutrient levels in the soil.
Drosera indica is an insectivorous plant, a sundew native to tropical countries throughout the world, from Asia to Africa, but absent from the neotropics. Together with Australian endemic species D. aquatica, D. aurantiaca, D. barrettorum, D. cucullata, D. finlaysoniana, D. fragrans, D. glabriscapa, D. hartmeyerorum, D. nana, D. serpens it makes up the section Arachnopus.
Drosera sect. Erythrorhiza is a section of 14 species of tuberous species in the genus Drosera. It represents a natural group of all the rosetted tuberous Drosera. Most species are endemic to Western Australia, but D. aberrans, D. praefolia, D. schmutzii, and D. whittakeri are also found in eastern Australia.

Drosera glanduligera, commonly known as the pimpernel sundew or scarlet sundew, is a species of carnivorous plant endemic to southern Australia. It is an ephemeral annual plant that grows in the winter and flowers from August to November.
Drosera meristocaulis is a perennial species in the carnivorous plant genus Drosera, the only member of the subgenus Meristocaulis. It is a small, rosette- and branched stem-forming sundew that has many morphological affinities to the Australian pygmy sundews. D. meristocaulis is wholly endemic to Pico da Neblina, an isolated mountain on the Brazil-Venezuela border.
Drosera dilatatopetiolaris is a carnivorous plant in the genus Drosera and is endemic to Australia, being found in both Western Australia and the Northern Territory. Its leaves are arranged in a rosette and commonly produces plantlets, eventually forming large clumps that can be over 1 ft (0.3 m) across. Green petioles emerging from the center of the rosette are typically 3–5 mm wide, but can vary. Red carnivorous leaves at the end of the petioles are small and round, with most resting on the soil surface. Inflorescences are 18 cm (7 in) long with white flowers being produced from April to May. It has a diploid chromosome number of 2n = 12.
Drosera magnifica is a species of sundew endemic to Pico do Padre Ângelo in eastern Minas Gerais in southeastern Brazil, where it grows among sandstone outcrops in herbaceous and shrubby vegetation. It is one of the three largest species of Drosera – the other two being D. regia from South Africa and D. gigantea from Australia – and was discovered in 2015 through images which appeared on the social network Facebook. It is the largest New World sundew, and it is closely related to Drosera graminifolia and Drosera spiralis. According to the IUCN Red List categories and criteria, it is considered Critically Endangered. Brazil is home to some 30 species of Drosera.
Drosera citrina is a pygmy sundew, a type of carnivorous plant. It is native to Western Australia. The Latin specific epithet citrina means "lemon coloured", referring to the colour of the flowers. It is closely related to Drosera nivea, which was considered a variety of D. citrina in the past called Drosera citrina var. nivea
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 albonotata is a species of pygmy sundew native to Western Australia. It was first described by Alastair Robinson, Adam Cross, Manfred Meisterl and Andreas Fleischmann in 2018.
Andreas Fleischmann is a German botanist specialising in carnivorous plants, particularly Droseraceae and Lentibulariaceae. He has (co-)published at least 46 new taxa including 14 species of Drosera (sundews), 7 species of Genlisea, 8 species of Heliamphora and 3 species of Pinguicula (butterworts).
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.
