In the fields of horticulture and botany, the term deciduous means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen.
Toxicodendron radicans, commonly known as eastern poison ivy or poison ivy, is an allergenic Asian and Eastern North American flowering plant in the genus Toxicodendron. The species is well known for causing urushiol-induced contact dermatitis, an itchy, irritating, and sometimes painful rash, in most people who touch it. The rash is caused by urushiol, a clear liquid compound in the plant's sap. The species is variable in its appearance and habit, and despite its common name, it is not a true ivy (Hedera), but rather a member of the cashew and pistachio family (Anacardiaceae). T. radicans is commonly eaten by many animals, and the seeds are consumed by birds, but poison ivy is most often thought of as an unwelcome weed. It is a different species from western poison ivy, Toxicodendron rydbergii, which has similar effects.
Acer negundo, the box elder, boxelder maple, Manitoba maple or ash-leaved maple, is a species of maple native to North America. It is a fast-growing, short-lived tree with opposite, compound leaves. It is sometimes considered a weedy or invasive species, and has been introduced to and naturalized throughout much of the world, including in South America, Australia, New Zealand, South Africa, much of Europe, and parts of Asia.
Ranunculus is a large genus of about 600 species of flowering plants in the family Ranunculaceae. Members of the genus are known as buttercups, spearworts and water crowfoots.
Poison dart frog is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive this from their diet of ants, mites and termites. Other species however, that exhibit cryptic coloration and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are threatened due to human infrastructure encroaching on their habitats.
Commonly known as hellebores, the Eurasian genus Helleborus consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae). Many hellebore species are poisonous.
Nerium oleander, most commonly known as oleander or nerium, is a shrub or small tree cultivated worldwide in temperate and subtropical areas as an ornamental and landscaping plant. It is the only species currently classified in the genus Nerium, belonging to subfamily Apocynoideae of the dogbane family Apocynaceae. It is so widely cultivated that no precise region of origin has been identified, though it is usually associated with the Mediterranean Basin.
Sodium fluoroacetate is an organofluorine chemical compound with the formula FCH2CO2Na. This colourless salt has a taste similar to that of sodium chloride and is used as a rodenticide. Both sodium and potassium salts are derivatives of fluoroacetic acid.
Cicuta, commonly known as water hemlock, is a genus of four species of highly poisonous plants in the family Apiaceae. They are perennial herbaceous plants which grow up to 2.5 meters (8.2 ft) tall, having distinctive small green or white flowers arranged in an umbrella shape (umbel). Plants in this genus may also be referred to as cowbane or poison parsnip. Cicuta is native to temperate regions of the Northern Hemisphere, mainly North America and Europe, typically growing in wet meadows, along streambanks and other wet and marshy areas. These plants bear a close resemblance to other members in the family Apiaceae and may be confused with a number of edible or poisonous plants. The common name hemlock may also be confused with poison hemlock, or with the Hemlock tree.
The Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP) is an Australian legislative instrument produced by the Therapeutic Goods Administration (TGA). Before 2010, it was known as the Standard for the Uniform Scheduling of Drugs and Poisons (SUSDP). The SUSMP classifies drugs and poisons into different Schedules signifying the degree of control recommended to be exercised over their availability to the public. As of 2021, the most recent version is the Poisons Standard February 2021.
Dichapetalaceae is a family of flowering plants, consisting of 3 genera and about 170 species. Members of this family are trees, shrubs or lianas found in tropical and subtropical regions of the world.
Eucalyptus oil is the generic name for distilled oil from the leaf of Eucalyptus, a genus of the plant family Myrtaceae native to Australia and cultivated worldwide. Eucalyptus oil has a history of wide application, as a pharmaceutical, antiseptic, repellent, flavouring, fragrance and industrial uses. The leaves of selected Eucalyptus species are steam distilled to extract eucalyptus oil.
Withrow Park is a 8.5-hectare (21-acre) park in the Riverdale neighbourhood of Toronto, Ontario, Canada. Laid out and constructed in the 1910s, at the same time that the surrounding community was built, Withrow Park is among Toronto's large multi-purpose parks. The park is bounded by Carlaw Avenue on the east, Bain Avenue on the south, Logan Avenue on the west and McConnell Avenue on the north.
Dichapetalum cymosum, commonly known as gifblaar from Afrikaans, or occasionally by its English translation, poison leaf, is a small prostrate shrub occurring in northern parts of Southern Africa in the family Dichapetalaceae. It is notable as a common cause of lethal cattle poisoning in this region and is considered one of the 'big 6' toxic plants of cattle in South Africa. A 1996 estimate of plant poisonings in South Africa attributes 8% of cattle mortality caused by poisonous plants to it. The majority (70%) of fatal cases are in Limpopo province, with 10% each in North West, Mpumalanga, and Gauteng. Fluoroacetate, the poison used to synthetically produce Compound 1080 used extensively in New Zealand, occurs in all parts of the plant and is responsible for the toxic effects shown.
The Pretoria National Botanical Garden is one of South Africa's nine National Botanical Gardens. The garden is wedged between Pretoria Road and Cussonia Avenue in Brummeria, in eastern Pretoria, Gauteng, and flanks a central rocky ridge that runs from east to west. The 76 hectares (0.76 km2) garden was established in 1946, and of late hosts the headquarters of the South African National Biodiversity Institute.
Conium maculatum, colloquially known as hemlock, poison hemlock or wild hemlock, is a highly poisonous biennial herbaceous flowering plant in the carrot family Apiaceae, native to Europe and North Africa. A hardy plant capable of living in a variety of environments, hemlock is widely naturalized in locations outside its native range, such as parts of Australia, West Asia, and North and South America, to which it has been introduced. It is capable of spreading and thereby becoming an invasive weed.
Poison ivy is a type of allergenic plant in the genus Toxicodendron native to Asia and North America. Formerly considered a single species, Toxicodendron radicans, poison ivies are now generally treated as a complex of three separate species: Toxicodendron radicans, Toxicodendron rydbergii, and Toxicodendron orientale. They are well known for causing urushiol-induced contact dermatitis, an itchy, irritating, and sometimes painful rash, in most people who touch it. The rash is caused by urushiol, a clear liquid compound in the plant's sap. They are variable in appearance and habit, and despite its common name, it is not a "true" ivy (Hedera), but rather a member of the cashew and pistachio family (Anacardiaceae). T. radicans is commonly eaten by many animals, and the seeds are consumed by birds, but poison ivy is most often thought of as an unwelcome weed.
Gorgyra afikpo, the large leaf sitter, is a butterfly in the family Hesperiidae. It is found in Senegal, Sierra Leone, Ivory Coast, Ghana, Nigeria, Cameroon, the Republic of the Congo, the Central African Republic, Uganda and north-western Tanzania. The habitat consists of forests.
Dichapetalum madagascariense is a plant species originally described from Madagascar but now reported from many parts of mainland tropical Africa as well. It is reported from a wide region from Mozambique north to Tanzania and west to Liberia.
Dichapetalins are a small class of triterpenoid compounds found primarily in the Dichapetalaceae family but also reportedly in Phyllanthus (Euphorbiaceae). They are structural derivatives of dammarene characterized by a C6C2 unit connected to a dammarene or a 13,30-cyclodammarane skeleton with variable C-17 side chains containing actone, spirolactone, lactol, acetal, or furan moieties. They have been found to display cytotoxicity against several cancer cell lines.
