Drosera arenicola is a species of sundew endemic to Venezuela. It was first described by Julian Alfred Steyermark in 1952. [1]
D. arenicola is an upland species found only in Amazonas and Bolívar states in Venezuela. It has been collected from elevations above 1,200 m (3,900 ft) including on tepui plateaus. [2]
A perennial sundew forming compact rosettes of linear-spathulate, semi-erect leaves. As the leaves age they reflex markedly. The plant gradually forms an upright stem of old dead growth and can attain a height of 6 cm. White flowers are held on short scapes up to 1.5 cm tall. [2]
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 aliciae, the Alice sundew, is a carnivorous plant in the family Droseraceae. It is native to the Cape Provinces of South Africa, like Drosera capensis, the cape sundew, and is one of the most common sundews in cultivation. The plant forms small, tight rosettes of wedge-shaped leaves, up to 5 cm in diameter. Under conditions of good lighting, the insect-snagging tentacles will become deeply coloured with anthocyanin pigments, which probably aid in its attraction of insect prey. The plant is relatively easy to grow, and produces attractive scapes of pink flowers, which are held about 30 cm away from the carnivorous leaves, so as to prevent pollinators from becoming ensnared. D. aliciae is very similar in form to a number of other closely related species such as D. slackii, and D. natalensis: the former is rather larger with a slightly different growth habit(8 cm diameter); the latter has hairier stipules and a larger distance between leaf base and the “sticky” trichomes.
Drosera capensis, commonly known as the Cape sundew, is a small rosette-forming carnivorous species of perennial sundew native to the Cape in South Africa. Because of its size, easy-to-grow nature, and the copious amounts of seed it produces, it has become one of the most common sundews in cultivation, and thus, one of the most frequently introduced and naturalised invasive Drosera species.
Drosera rotundifolia, the round-leaved sundew, roundleaf 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 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.
Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous flowering plant species belonging to the sundew family Droseraceae. It is a temperate species with a circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauai in Hawaii, where it grows as a tropical 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. It 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 intermedia, commonly known as the oblong-leaved sundew, spoonleaf sundew, or spatulate leaved sundew, is an insectivorous plant species belonging to the sundew genus. It is a temperate or tropical species native to Europe, southeastern Canada, the eastern half of the United States, Cuba, Hispaniola, and northern South America.
Drosera nidiformis is tropical African sundew. This plant is indigenous to KwaZulu-Natal in South Africa. Its classification is ambiguous; some sources refer to it as a synonym of Drosera dielsiana whereas others treat it as a separate species. This plant was previously known as Drosera "maglisburg".
Drosera linearis, commonly called the slenderleaf sundew, is a sundew found in the Great Lakes region of North America, in Canada and the United States, such as Michigan, and in Montana. It is usually no more than four inches tall.
Drosera andersoniana, the sturdy sundew, 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 8–25 cm (3–10 in). Its pink-white to red flowers emerge from August to September. D. andersoniana grows in loamy soils near granite outcrops.
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 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 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 viridis is a semi-erect or rosetted perennial species in the carnivorous plant genus Drosera. It is known only from Brazil, being found in eastern Paraná and São Paulo and central Santa Catarina at elevations from 550–1,100 m (1,800–3,610 ft). It may, however, also be found in adjacent Argentina, Paraguay, and Uruguay. It typically grows in waterlogged habitats among grasses in white-clayey, reddish lateritic, or humus-rich black-brown soils and is sometimes found submerged with only the leaves above water.
Drosera kaieteurensis is a plant from the sundew family (Droseraceae).
Drosera hookeri, the grassland sundew is an shortly erect perennial tuberous species in the carnivorous plant genus Drosera. Drosera hookeri is found in south-eastern Australia. Although the holotype was collected in Tasmania, its distribution also includes Victoria, New South Wales and South Australia. This species has a complex taxonomic history, and its specific epithet acknowledges the original recognition of the taxon by Joseph Dalton Hooker. Hooker originally called his species Drosera foliosa Hook.f. ex Planch. in 1848, a name that was illegitimate as it had previously been used to describe a different species. The nomenclature of D. hookeri was later clarified and the taxonomic concept significantly broadened to include most of the south-eastern Australian and New Zealand forms of the species complex that includes Drosera peltata.
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.
