Ctenolepis is a plant genus in the family Cucurbitaceae.
The Plant List recognises 3 accepted species: [2]
Aeschynanthus is a genus of about 150 species of evergreen subtropical and tropical plants in the family Gesneriaceae. They are usually trailing epiphytes with brightly colored flowers that are pollinated by sunbirds. The genus name comes from a contraction of aischuno and anthos (flower). The common name for some species is "lipstick plant", which comes from the appearance of the developing buds. A full list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.
Nepenthes stenophylla, or the narrow-leaved pitcher-plant, is a tropical pitcher plant endemic to Borneo. The species produces attractive funnel-shaped pitchers up to 25 cm high. It is listed as Least Concern on the IUCN Red List. Nepenthes stenophylla belongs to the loosely defined "N. maxima complex", which also includes, among other species, N. boschiana, N. chaniana, N. epiphytica, N. eymae, N. faizaliana, N. fusca, N. klossii, N. maxima, N. platychila, and N. vogelii.
Nepenthes sanguinea is a large and vigorous Nepenthes pitcher plant species, native to Peninsular Malaysia and southernmost Thailand, where it grows at 300–1800 metres altitude. The pitchers are variable in size, from 10–30 cm tall, and range from green and yellow to orange and red. The insides of the pitchers are usually speckled with its two main colors. It was introduced to Victorian Britain around 1847 by Cornish plant hunter and botanist Thomas Lobb via the Veitch Nurseries.
Nepenthes macfarlanei is a carnivorous pitcher plant species endemic to Peninsular Malaysia. It produces attractive red-speckled pitchers. Lower pitchers are ovoid or infundibular in the lower half and globose or cylindrical above and up to 25 cm high. Upper (aerial) pitchers are of a lighter colour with wings reduced to rubs. The lower surface of the lid is densely covered with short, white hairs. This is a characteristic morphological feature of this species, but at present its function is unknown.
Nepenthes clipeata, or the shield-leaved pitcher-plant, is a tropical pitcher plant known only from the near-vertical granite cliff faces of Mount Kelam in Kalimantan, Borneo. It has an altitudinal distribution of approximately 600 to 800 m.
Nepenthes angasanensis is a tropical pitcher plant species endemic to Sumatra, where it grows at an altitude of 1,400 metres (4,600 ft) to 3,100 metres (10,200 ft) above sea level. The status of this taxon is controversial as it is similar in morphology to N. mikei and N. tobaica. It has even been suggested that the taxon might represent a natural hybrid between N. densiflora and N. tobaica.
Nepenthes treubiana is a tropical pitcher plant native to Western New Guinea and the island of Misool.
Nepenthes rowaniae is a species of pitcher plant endemic to the Cape York Peninsula, Australia. It is closely related to N. mirabilis and was once considered an extreme form of this species.
Nepenthes densiflora is a tropical pitcher plant endemic to Sumatra, where it grows at an altitude of between 1700 and 3200 m above sea level.
Oenanthotoxin is a toxin extracted from hemlock water dropwort and other plants of the genus Oenanthe. It is a central nervous system poison, and acts as a noncompetitive antagonist of the neurotransmitter gamma-aminobutyric acid. A case has been made for the presence of this toxin in local Oenanthe species playing a causative role in euthanasia in ancient Sardinia. It was crystallized in 1949 by Clarke and co-workers. It is structurally closely related to the toxins cicutoxin and carotatoxin. Oenanthotoxin is a C17 polyacetylene isomer of cicutoxin.
Charles Baron Clarke was a British botanist. He was born at Andover, the eldest son of Turner Poulter Clarke. He was educated at King's College School, London, and at Trinity and Queens' Colleges, Cambridge. He began the study of law at Lincoln's Inn in 1856 and was called to the bar in 1860. He lectured in mathematics at Presidency College, Calcutta, from 1857 to 1865. Clarke was Inspector of Schools in Eastern Bengal and later of India, and superintendent of the Calcutta Botanical Garden from 1869 to 1871. He retired from the Indian Civil Service in 1887. He was president of the Linnean Society from 1894 to 1896, and was elected a fellow of the Royal Society in 1882. He worked at Royal Botanic Gardens Kew until his death in 1906.
Sir Arthur Charles Clarke was an English science-fiction writer, science writer, futurist, inventor, undersea explorer, and television series host.
Nepenthes appendiculata is a tropical pitcher plant known only from the Hose Mountains of central Sarawak, Borneo, where it grows at elevations of 1450–1700 m above sea level. The species is characterised by an enlarged glandular appendage on the lower lid surface, for which it is named.
Nepenthes abalata is a tropical pitcher plant known from three western islands of the Philippines: Culion, Cuyo, and Malalison. It has been recorded from coastal grassland and scrub at elevations of 0–20 m above sea level.
Ctenolepis garcini, also known as Garcin's bur cucumber, is a tender climber of the family Cucurbitaceae. It is one of the three species of the genus Ctenolepis. It is widely distributed in southern India and Ceylon. The species was named after French botanist Laurent Garcin, who traveled India in the 18th century.
Petalidium, commonly known as petal-bushes, is a genus of perennial shrubs in the acanthus family. They are native to sandy flats or stony slopes in the drier bush regions of Africa, India and the Mascarene Islands. The majority of species occur in frost-free, summer rainfall regions of southern Africa, and may be found from low to medium altitudes.
