Drosera, 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.
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 rotundifolia, the round-leaved sundew or common sundew, is a carnivorous species of flowering plant that grows in bogs, marshes and fens. One of the most widespread sundew species, it has a circumboreal distribution, being found in all of northern Europe, much of Siberia, large parts of northern North America, Korea and Japan but is also found as far south as California, Mississippi and Alabama in the United States of America and in New Guinea.
Drosera adelae, commonly known as the lance-leaved sundew, is a carnivorous plant in the genus Drosera that is endemic to Queensland, Australia.
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 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 bulbosa, the red-leaved sundew, is a perennial tuberous species in the genus Drosera that is endemic to Western Australia. It grows in a rosette and produces white flowers emerge from April to June. D. bulbosa was first formally described by William Jackson Hooker in 1841.
Drosera stenopetala is an insectivorous, rosette-forming perennial sub-alpine or alpine herb. The specific epithet means "with narrow petals", which is somewhat misleading given that the petals of this plant are fairly wide. A species of sundew, it is unique within its genus in being endemic to New Zealand. It is one of New Zealand's two alpine species of Drosera, the other being Drosera arcturi. Characteristic features include involute petioles and upright leaves. Its range extends from the Ruahine and Tararua Ranges in the north down the Southern Alps to Stewart Island. It is also found on the Auckland Islands and Campbell Island.
Drosera gibsonii is a species of pygmy sundew endemic to Stirling Range National Park in Western Australia. It is thought to be most closely related to Drosera silvicola.
Drosera solaris is a species of sundew native to the highlands of Guyana. It is thought to be most closely related to Drosera felix and Drosera kaieteurensis.
Drosera fimbriata, the Manypeaks sundew, is a perennial tuberous species in the genus Drosera that is endemic to Western Australia. It grows to 10 to 15 cm tall with two or three whorls of non-carnivorous leaves on the lower portion of the stem and 2 to 5 whorls of carnivorous leaves above that. It is native to a region mostly around Manypeaks but with populations near the Scott River and near Denmark. It grows in winter-wet sandy soils in heathland. It flowers in October.
Drosera platypoda, the fan-leaved sundew, is a tuberous perennial species in the genus Drosera that is endemic to south-west Western Australia. It grows 15 to 20 cm tall with a basal rosette of leaves with alternate cauline leaves along the stem. It is native to a region from Manjimup south-west to an area around the Scott River and east to Cape Riche. It grows in winter-wet sandy soils in heathland. It flowers in October.
Drosera macrophylla, the showy sundew, is a perennial tuberous species in the genus Drosera that is endemic to Western Australia. It grows in a rosette with leaves 4 cm (2 in) long and 2 cm (1 in) wide. It is a common species east of Perth. It grows in loam soils. It flowers from June to October. D. macrophylla was first described by John Lindley in his 1839 publication A sketch of the vegetation of the Swan River Colony. In 1992, Allen Lowrie and Sherwin Carlquist described a new subspecies, D. macrophylla subsp. monantha, which is distinguished from D. macrophylla subsp. macrophylla by its single-flowered or rarely biflowered inflorescences. Subspecies monantha is abundant in the Bruce Rock/Merredin region.
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 bulbigena, the midget sundew, is an erect perennial tuberous species in the genus Drosera that is endemic to Western Australia and occurs in an area near Perth and to its south along the coast. It grows to 3–6 cm (1–2 in) high and produces white flowers from August to October. D. bulbigena grows in swamps and winter-wet depressions.
Drosera huegelii, the bold sundew, is an erect perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows in sandy soils in winter-wet depressions and margins of swamps and occurs along the south-west coast of Australia. D. huegelii produces small, bell-shaped leaves along an erect stem that can be 10–50 cm (4–20 in) tall. White to cream-coloured flowers emerge from June to September.
Drosera sulphurea, the sulphur-flowered sundew, is a scrambling perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and is found in coastal areas in sandy loam, often among Cephalotus. D. sulphurea produces small, shield-shaped carnivorous leaves along stems that can be 40–60 cm (16–24 in) high. Yellow flowers bloom in September.
Drosera ultramafica is a species of sundew native to the highlands of Malesia. It is thought to be most closely related to Drosera spatulata, Drosera neocaledonica and Drosera oblanceolata. The taxon is readily distinguished from the former by its general habit and preference for mafic, upland habitats, and from the latter species by specific morphological differences, in addition to the fact that their geographical ranges do not overlap.
Buckleria parvulus, the sundew plume moth, is a moth of the family Pterophoridae. The species was first described by William Barnes and Arthur Ward Lindsey in 1965 from Archbold Biological Station, Florida. It is found in the south-eastern United States, including Florida, North Carolina, Louisiana, Alabama, Georgia, Mississippi, South Carolina and Texas.
