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.
Drosophyllum is a genus of carnivorous plants containing the single species Drosophyllum lusitanicum. In appearance, it is similar to the related genus Drosera, and to the much more distantly related Byblis.
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 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 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, southern China and Japan, Micronesia, Papua New Guinea, eastern Australia, 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 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 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 and northern South America.
Drosera ordensis is a species of sundew, native to Australia and part of the "petiolaris complex" of sundews making up the subgenus Lasiocephala. Compared to many petiolaris sundews, it has wide petioles, which are densely covered in silvery hairs. It usually forms rosettes 8 cm across, although plants up to 20 cm in diameter have been reported.
Eurybia divaricata, commonly known as the white wood aster, is an herbaceous plant native to eastern North America. It occurs in the eastern United States, primarily in the Appalachian Mountains, though it is also present in southeastern Canada, but only in about 25 populations in the provinces of Ontario and Quebec. In the U.S. it is abundant and common, but in Canada it is considered threatened due to its restricted distribution. It can be found in dry open woods as well as along wood-edges and clearings. The species is distinguished by its flower heads that have yellow centers and white rays that are arranged in flat-topped corymbiform arrays, emerging in the late summer through fall. Other distinguishing characteristics include its serpentine stems and sharply serrated narrow heart-shaped leaves. The white wood aster is sometimes used in cultivation in both North America and Europe due to it being quite tough and for its showy flowers.
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 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..
Drosera kaieteurensis is a plant from the sundew family (Droseraceae).
Dilatris is a genus of four species of evergreen perennial herbaceous plants of up to 60 cm (2.0 ft) high, that are assigned to the bloodroot family. The plants have hairless, line- to lance-shaped leaves set in a fan that emerges from a red or orange coloured rootstock. The mauve or dirty yellow flowers have six free tepals that have some gland dots near their tips. One stamen is short, upright, with a large, yellow anther, the other two are longer, spreading, with smaller scarlet anthers. The style is diverted from the centre opposite both longer stamens. The species only occur in the Western Cape and Northern Cape provinces of South Africa.
Leucadendron coniferum, also known at the dune conebush, is an evergreen, dioecious shrub or small tree of up to 4 m (13 ft) high, that has been assigned to the family Proteaceae. It has a whorl of conspicuous yellow leaves subtending the flowerheads. The flowers can be found in August and September. It grows in sandy soils near the coast of the Western Cape province of South Africa.
Leucospermum lineare is an evergreen shrub with linear leaves and is assigned to the Proteaceae. There are two distinct forms that have not been formally recognized as separate taxa. There is an upright form with orange flower heads of up to 2 m (6.6 ft) high, and a sprawling form of 2–3 m (6.6–9.8 ft) in diameter with yellow flower heads. Its common name is needle-leaf pincushion, or narrow-leaf pincushion, in English and smalblaarspeldekussing in Afrikaans. The orange-flowered form is called tangerine pincushion or assegaaibos pincushion. Flowering occurs in the first half of the southern hemisphere season, but peaks in September and October. It is an endemic species that can only be found in the southwest of the Western Cape province of South Africa.
Leucospermum grandiflorum is an evergreen, upright shrub of up to 2½ m high that is assigned to the family Proteaceae. It has elliptic, greyish green, softly hairy leaves and initially egg-shaped heads with yellow flowers, later flatter with flowers turning orange. From the center of each flower emerges a long pale yellow style with a pink thickened tip that is bent slightly clockwise, giving the entire head the appearance of a pincushion. Its flowers can be found between July and December. It is called grey-leaf fountain-pincushion or rainbow pincushion in English. L. grandiflorum is an endemic species that can only be found in nature in the Western Cape province of South Africa.
Leucospermum secundifolium is a low, evergreen shrub that grows along the ground, the tip of the branches slightly rising, which has been assigned to the family Proteaceae. It has narrowly elliptic leaves with a distinct leafstalk, and few-flowered and very small heads of 1–1½ cm (0.4–0.6 in) across. It is called stalked pincushion in English. The sweetly scented flower heads may be found around early December. It is an endemic species that only grows in a small area of the Western Cape province of South-Africa.
