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 pedicellaris is a pygmy species of the sundew genus (Drosera). It was discovered in 1997 and described in 2002 by Allen Lowrie. It is endemic to Western Australia.
Drosera indica, sometimes known as the Indian sundew, is a species of sundew native to tropical and southern Africa, Madagascar and tropical and subtropical Asia. It was first described by Carl Linnaeus in his Species Plantarum in 1753. Until the early 21st century it was mostly considered a highly variable species with a wide distribution including Australia, but since 2000 several distinct species have been separated from D. indica within Drosera section Arachnopus, which is often referred to as the ‘Drosera indica complex’. Many of these species are endemic to Australia, but D. indica itself is now widely considered to be absent from that country.
Drosera scorpioides, commonly called the shaggy sundew, is a pygmy sundew native to the Jarrah Forest region and southern coasts of Southwest Australia. Notable for its unusually large size relative to other pygmy sundews, D. scorpioides can produce rosettes measuring up to two inches in diameter and specimens may attain a height of up to 100 millimeters. The species is found on white sand and clay, near swamps, on sand ridges, and is associated with laterite. The flowers are pink and white, appearing sometime between August and October. Depending on the form, D. scorpioides can be expected to live up to seven years.

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 kaieteurensis is a plant from the sundew family (Droseraceae).
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 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 citrina is a species of pygmy sundew in the family Droseraceae. It is a carnivorous plant 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 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 maanyaa-gooljoo is a species of sundew endemic to the Kimberley region of Western Australia. It was first described by Andreas Fleischmann and Thilo Krueger in 2023. The type material was collected much earlier, in 1982, but was originally categorised within D. indica and later as a form of D. fragrans. Like other members of Drosera sect. Arachnopus it is an annual therophyte.
Drosera margaritacea is a species of sundew endemic to the Kimberley region of Western Australia. It was first described by Thilo Krueger and Andreas Fleischmann in 2021. 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.
