Drosera slackii | |
Drosera slackii is a subtropical sundew native to the Cape Provinces of South Africa. [2] It forms rosettes that range from to two to four inches in diameter, and produces pink flowers. It is named after the British plantsman and author Adrian Slack (1933-2018). [3] [4]
Drosera slackii is a recipient of the Royal Horticultural Society's Award of Garden Merit. [5]
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 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.
Adrian Slack was a landscape gardener, plantsman, author and authority on carnivorous plants. He won 5 gold medals at the Chelsea Flower Show, and authored two books: Carnivorous Plants and Insect-Eating Plants and How to Grow Them.
The Carnivorous Plant Newsletter is the official publication of the International Carnivorous Plant Society (ICPS), the largest such organization in the world. It is headquartered in Walnut Creek, California.
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 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".
Plumbago auriculata, the cape leadwort, blue plumbago or Cape plumbago, is a species of flowering plant in the family Plumbaginaceae, native to South Africa.
Peter Geoffrey Taylor (1926–2011) was a British botanist who worked at Royal Botanic Gardens, Kew throughout his career in botany. Taylor was born in 1926 and joined the staff of the herbarium at Kew in 1948. He published his first new species, Utricularia pentadactyla, in 1954. In 1973, Taylor was appointed curator of the orchid division of the herbarium and, according to Kew, "under his direction, orchid taxonomy was revitalised and its horticultural contacts strengthened."
Drosera zonaria, the painted sundew, is a perennial tuberous species in the carnivorous plant genus Drosera and is endemic to south-west Western Australia from near Perth southeast to near Esperance. It grows in a tight rosette approximately 5 to 7 cm in diameter with 20 to 30 green to red leaves that are arranged in concentric layers. The leaves are typically 1 cm wide and are usually described as being "kidney-shaped" with crimson leaf margins. It grows in deep silica sands in open woodland or coastal heathland and only flowers after a bush fire, which is speculated to be caused by the release of ethylene. Its white, sweetly perfumed flowers, which are very similar to those of D. erythrorhiza, emerge on 4 to 5 cm tall scapes. As with most other tuberous Drosera species, D. zonaria will die back during the dry summer months and retreat to the fleshy tuber 10 to 30 cm below ground.
Drosera dielsiana is a compact rosetted sundew native to South Africa, Eswatini (Swaziland), Mozambique, Malawi, and Zimbabwe. It was described as a new species by Arthur Wallis Exell and Jack Rodney Laundon in 1956. The diploid chromosome number is 2n=40. It was named in honor of Ludwig Diels, the author of the 1906 monograph on the Droseraceae.
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.
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 subg. Lasiocephala, sometimes collectively known as the petiolaris-complex, is a subgenus of 14 species in the genus Drosera. These species are distinguished by their subpeltate to peltate lamina.
Drosera lanata is a carnivorous plant in the genus Drosera and is endemic to the Northern Territory and Queensland in Australia. Its leaves are arranged in a compact basal rosette. Narrow linear petioles less than 2 mm wide emerge from the center of the rosette and hold carnivorous leaves at the end. Both petioles and the center of the rosette are densely covered in silvery dendritic hairs. These dendritic hairs afford the plant insulation and allow it to trap morning dew for additional moisture during the dry season. The leaf lamina is maroon-red and 2 mm long by 2.5 mm wide.
Planta Carnivora is a biannual periodical and the official publication of The Carnivorous Plant Society of the United Kingdom. Typical articles include matters of horticultural interest, field reports, and news of plant discoveries. The journal was established in 1980 and was called The Carnivorous Plant Society Journal until 2009; the following year it was combined with the society's newsletter to form Planta Carnivora. Issues are published in spring and autumn.
Drosera zeyheri is a species in the carnivorous plant genus Drosera that is endemic to the Cape Provinces of South Africa. Some botanists treat this species to be a form of D. cistiflora. It differs from typical D. cistiflora specimens by being smaller, sometimes having cauline leaves on the short stems with white, pink, or red flowers. Botanist Fernando Rivadavia has said that he believes of all the forms and varieties in the D. cistiflora complex, D. zeyheri could possibly merit distinction at the species rank. He found it easy to distinguish it from D. cistiflora by its mostly stemless habit, though it often does present one to three leaves on the flower scape. Drosera zeyheri was first described by Terence Macleane Salter in a 1940 volume of the Journal of South African Botany.
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 trinervia is a species in the carnivorous plant genus Drosera that is endemic to the Cape Provinces of South Africa. It was first described by Kurt Polycarp Joachim Sprengel in his 1820 work Neue Entdeckungen im ganzen Umfang der Pflanzenkunde.
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.
