Droseraceae is a family of carnivorous flowering plants, also known as the sundew family. It consists of approximately 180 species in three extant genera. Representatives of the Droseraceae are found on all continents except Antarctica.
Drosera brevifolia, is a carnivorous plant of the family Droseraceae and is the smallest sundew species native to the United States. This species differs considerably from the pink sundew, Drosera capillaris, by its wedge-shaped leaves, and distinctly deeper red to reddish purple color, noticeable when side by side with D. capillaris.
Drosera spatulata, the spoon-leaved sundew, is a variable, rosette-forming sundew with spoon-shaped leaves. The specific epithet is Latin for "spatula shaped," a reference to the form of the leaves. This sundew has a large range and occurs naturally throughout Southeast Asia, in southern China and Japan, Micronesia, New Guinea through to the eastern territories of Australia and Tasmania and New Zealand. Variants are often known by the localities in which they are found. The plant does not form hibernacula in winter, and is easily grown using the same methods as Drosera capensis.
Drosera regia, commonly known as the king sundew, is a carnivorous plant in the sundew genus Drosera that is endemic to a single valley in South Africa. The genus name Drosera comes from the Greek word droseros, meaning "dew-covered". The specific epithet regia is derived from the Latin for "royal", a reference to the "striking appearance" of the species. Individual leaves can reach 70 cm (28 in) in length. It has many unusual relict characteristics not found in most other Drosera species, including woody rhizomes, operculate pollen, and the lack of circinate vernation in scape growth. All of these factors, combined with molecular data from phylogenetic analysis, contribute to the evidence that D. regia possesses some of the most ancient characteristics within the genus. Some of these are shared with the related Venus flytrap (Dionaea muscipula), which suggests a close evolutionary relationship.
Drosera peltata, commonly called the shield sundew or pale sundew, is a climbing or scrambling perennial tuberous species in the carnivorous plant genus Drosera. Among the tuberous sundews, D. peltata has the largest distribution, which includes eastern and western Australia, New Zealand, India, and most of Southeast Asia including the Philippines. The specific epithet is Latin for "shield shaped", a reference to the shape of the cauline leaves. It is either a single extremely variable species, or a complex of several closely related species of uncertain taxonomic boundaries. In Australia at least four forms have had or still have specific taxonomic recognition: Drosera peltata subsp. peltata, D. peltata subsp. auriculata, D. foliosa and D. gracilis.
Drosera adelae, commonly known as the lance-leaved sundew, is a carnivorous plant in the genus Drosera that is endemic to Queensland, Australia.
Aldrovanda is a genus of carnivorous plants encompassing one extant species and numerous extinct taxa. The genus is named in honor of the Italian naturalist Ulisse Aldrovandi, the founder of the Botanical Garden of Bologna, Orto Botanico dell'Università di Bologna. Aldrovanda vesiculosa has been reported from scattered locations in Europe, Asia, Africa, and Australia.
Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous plant species belonging to the sundew family Droseraceae. It is a temperate species with a generally circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauaʻi in Hawaiʻi, where it grows as a subtropical sundew. It is thought to originate from an amphidiploid hybrid of D. rotundifolia and D. linearis, meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current D. anglica.
Drosera binata, commonly known as the forked sundew or fork-leaved sundew, is a large, perennial sundew native to Australia and New Zealand. The specific epithet is Latin for "having pairs" - a reference to the leaves, which are dichotomously divided or forked.
Drosera arcturi is a perennial, insectivorous species of sub-alpine or alpine herb native to Australia and New Zealand. It is one of New Zealand's two alpine species of sundew, the other being Drosera stenopetala. The specific epithet, which translates as "of Arthur" from Latin, is a reference to Mount Arthur, in north-eastern Tasmania, the type locality of the species.
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.
Alastair S. Robinson is a taxonomist and field botanist specialising in the carnivorous plant genus Nepenthes, for which he is regarded as a world authority. He is currently a manager at the National Herbarium of Victoria, Royal Botanic Gardens Melbourne, where he oversees identification botany services, the Library and Artwork components of the State Botanical Collection, and the botanical journal Muelleria, a peer-reviewed scientific journal on botany published by the Royal Botanic Gardens Victoria, for which he is Editor in Chief.
Drosera macrantha, the bridal rainbow, is a scrambling or climbing perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows in a variety of habitats, including winter-wet depressions in sandy, loamy, laterite, or quartzite soils. D. macrantha produces small, cup-shaped carnivorous leaves along a long stem that can be 0.16–1.5 m (0.5–4.9 ft) high as it climbs. Its 1 in (2.5 cm) white or pink flowers emerge from June to November, blooming earlier in the more northern range.
Drosera microphylla, the golden rainbow, is an erect perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and grows on granite outcrops or in sandy or laterite soils. D. microphylla produces small, circular, peltate carnivorous leaves along erect stems that can be 10–40 cm (4–16 in) high. It blooms from June to September, displaying its large golden sepals and smaller, variably-coloured petals. In populations near Perth, the petals are red, whereas petal colour near Albany tends to be orange. Some plants east of Esperance have white petals.
Drosera neesii, the jewel rainbow is an erect or twining perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and grows near swamps or granite outcrops in sand, clay, or laterite. D. neesii produces small, cup-shaped carnivorous leaves in groups of three along stems that can be 15–60 cm (6–24 in) high. Pink flowers bloom from August to December.
Drosera uniflora is a species in the carnivorous plant genus Drosera that is native to southern Chile, Argentina, and the Falkland Islands. It is a tiny sundew with a solitary white flower as its name would suggest. Stalked glands on its leaves, which secrete sticky mucilage at the tips, are used to capture and hold insect prey, from which the plant derives the nutrients it cannot obtain in sufficient quantity from the soil. It was formally described in 1809 by botanist Carl Ludwig Willdenow.
Drosera caduca is a perennial carnivorous plant in the genus Drosera that is endemic to Western Australia. Its leaves are arranged in a rosette with one or more rosettes emerging from the root stock. It produces white flowers from December to July. Drosera caduca grows in white sandy soils on creek margins from the Edkins Range to the southern part of the Prince Regent National Park and also on Augustus Island. It was first described by Allen Lowrie in 1996; the type specimen was collected from August Island on 27 May 1993. The specific epithet caduca comes from the Latin caducus meaning dropping off early, in reference to the absence of the insect-trapping trichomes on all but the juvenile leaves. This plant is unique in the genus by its lack of the sticky traps on the mature adult leaves.
Drosera dilatato-petiolaris 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 falconeri is a carnivorous plant in the genus Drosera. It is endemic to the Northern Territory of Australia.
Drosera peruensis is a carnivorous plant of the genus Drosera, commonly known as the Peruvian sundew. This Drosera species was first identified in Peru in 2002 by Tânia Regina dos Santos Silva and Mireya D. Correa following work to update the genus Drosera for the reference text, Flora Neotropica..
