Allium rouyi | |
Allium rouyi, is a species of plant which is endemic to Spain. Its natural habitats are Mediterranean-type shrubby vegetation and rocky areas.
Though it had been thought to be an extinct species, a population of the plant was rediscovered in 1995, from which the somatic chromosome number and detailed chromosome morphology were presented. Using this karyological data, relationships between Allium rouyi and allied species were discussed. [2]
Following this discovery, Allium rouyi was considered as critically endangered; however, recent research has proved that A. chrysonemumStearn and A. reconditumPastor, Valdés & Muñoz are synonyms with A. rouyi, and therefore, distribution of this species extends throughout the south of the Iberian Peninsula. [1]
Chives, scientific name Allium schoenoprasum, is a species of flowering plant in the family Amaryllidaceae that produces edible leaves and flowers. Their close relatives include the common onions, garlic, shallot, leek, scallion, and Chinese onion.
Prumnopitys taxifolia, the mataī or black pine, is an endemic New Zealand coniferous tree that grows on the North Island and South Island. It also occurs on Stewart Island/Rakiura but is uncommon there.
Endemism is the state of a species being native to a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be endemic to that particular part of the world.
The bristle-spined rat is an arboreal rodent from Atlantic forest in eastern Brazil. Also known as the bristle-spined porcupine or thin-spined porcupine, it is the only member of the genus Chaetomys and the subfamily Chaetomyinae. It was officially described in 1818, but rarely sighted since, until December 1986, when two specimens - one a pregnant female - were found in the vicinity of Valencia in Bahia. Since then it has been recorded at several localities in eastern Brazil, from Sergipe to Espírito Santo, but it remains rare and threatened due to habitat loss, poaching and roadkills.
Allium moly, also known as yellow garlic, golden garlic and lily leek, Is a species of flowering plant in the genus Allium, which also includes the flowering and culinary onions and garlic. A bulbous herbaceous perennial from the Mediterranean, it is edible and also used as a medicinal and ornamental plant.
The Cebu flowerpecker is a small passerine bird. It is endemic to Cebu Island in the Philippines. Feared to have become extinct early in the 20th century, it was rediscovered in 1992 in a small patch of limestone forest in the Central Cebu Protected Landscape. It has since been found at three other sites, namely the Nug-as forest of Alcoy, Mount Lantoy of Argao and the forests of Dalaguete. This four-colored bird normally grows to 11 or 12 centimeters. The male is characterized by a large, triangular, scarlet to vermilion coat stain. In the female, the top is brown. The Cebu flowerpecker consumes small fruits and mistletoe plants and is generally active in the mornings to avoid competition with more aggressive birds. Despite attempts to protect its habitat it remains critically endangered due to illegal logging.
The red-crested tree-rat or Santa Marta toro is a species of tree-rat found in the monotypic genus Santamartamys in the family Echimyidae. It is nocturnal and is believed to feed on plant matter, and is mainly rufous, with young specimens having a grey coat. IUCN list the species as critically endangered: it is affected by feral cats, climate change, and the clearing of forest in its potential range in coastal Colombia.
Allium triquetrum is a bulbous flowering plant in the genus Allium native to the Mediterranean basin. It is known in English as three-cornered leek, and in Australia and New Zealand as onion weed. Both the English name and the specific epithet triquetrum refer to the three-cornered shape of the flower stalks.
Anogramma ascensionis, the Ascension Island parsley fern, is a species of fern in the family Pteridaceae that is endemic to Ascension Island, a volcanic island in the South Atlantic Ocean. It is one of eight putative species in the genus Anogramma. It was thought to have become extinct due to habitat loss, until four plants were found on the island in 2010. Over 60 specimens were then successfully cultivated at Royal Botanic Gardens, Kew and on Ascension Island. It is now classified as Critically Endangered.
Helicia is a genus of 110 species of trees and shrubs, constituting part of the plant family Proteaceae. They grow naturally in rainforests throughout tropical South and Southeast Asia, including India, Sri Lanka, Indochina, Peninsular Malaysia to New Guinea and as far south as New South Wales.
The caatinga vesper mouse is a rodent species in the family Cricetidae from South America. It is endemic to eastern Brazil, where it is found in open savanna (cerrado) and thorny scrub (caatinga) habitats. Its karyotype has 2n = 66 and FN = 68. It was formerly synonymized with C. callosus, but the latter has 2n = 50 and FN = 66. Karyologic analysis of C. expulsus has shown that the X chromosome is large and submetacentric while the Y chromosome is either acrocentric or submetacentric. Predators include the barn owl. Sexual dimorphism in shape and size occurs; the former is present mainly before the age of 20 days. Males are smaller before age 50 days and larger thereafter, which becomes less prominent after 200 days.
Georges Rouy was a French botanist who was among the first to identify infraspecific taxa, including: subspecies, varieties, and forms.
Allium lojaconoi, common name Maltese dwarf garlic, is a species of wild garlic endemic to the Republic of Malta in the Mediterranean. The species was first described in 1982 by Salvatore Brullo, E. Lanfranco and Pietro Pavone. It is closely related to A. parciflorum, from Sardinia and Corsica.
Gilliesieae is a tribe of herbaceous geophyte plants belonging to the subfamily Allioideae of the Amaryllis family (Amaryllidaceae). Described in 1826, it contains fifteen genera and about eighty species. It has been variously treated as a subfamily or tribe. It is native to the Southern United States, Central and South America, predominantly Chile. Of the three tribes of genera that make up the subfamily Allioideae, Gilliesieae is the largest and most variable. The tribe was divided into two tribes in 2014, Gilliesiae s.s. and Leucocoryneae, based on differences in floral symmetry and septal nectaries.
Allioideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. It was formerly treated as a separate family, Alliaceae. The subfamily name is derived from the generic name of the type genus, Allium. It is composed of about 18 genera.
Allium is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. The generic name Allium is the Latin word for garlic, and the type species for the genus is Allium sativum which means "cultivated garlic".
The Solanaceae, or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Allium dregeanum is the sole known species of Allium endemic to sub-Saharan Africa. It has also been described as the only Allium species endemic to the Southern Hemisphere, though some descriptions of the genus also include Allium juncifolium (Chile) and Allium sellovianum (Brazil), which are much less studied than Allium dregeanum. The distribution of Allium dregeanum extends from the summer-rainfall region, into the winter-rainfall zone of South Africa. Since Allium species are almost exclusively found in the Northern Hemisphere, with major centers of diversity in Central Asia and western North America, the biogeographical history of Allium dregeanum is of interest.
Allium bisotunense is a species of flowering plant in the family Amaryllidaceae and is endemic to Iran.
Allium akirense is a species of flowering plant in the family Amaryllidaceae endemic to Israel. Is it closely related to Allium qasyunense. It is diploid having 14 chromosomes.
