Clover, also called trefoil, are plants of the genus Trifolium, consisting of about 300 species of flowering plants in the legume family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 centimetres (12 in) tall. The leaves are trifoliate, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include Melilotus and Medicago.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists are produced by countries and organizations, which assess the risk of extinction to species within a political management unit.
A shamrock is a type of clover, used as a symbol of Ireland. Saint Patrick, one of Ireland's patron saints, is said to have used it as a metaphor for the Christian Holy Trinity. The name shamrock comes from Irish seamróg, which is the diminutive of the Irish word seamair and simply means "young clover".
Threatened species are any species which are vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment.
Trifolium repens, the white clover, is a herbaceous perennial plant in the bean family Fabaceae. It is native to Europe, including the British Isles, and central Asia and is one of the most widely cultivated types of clover. It has been widely introduced worldwide as a forage crop, and is now also common in most grassy areas of North America, Australia and New Zealand. The species includes varieties often classed as small, intermediate and large, according to height, which reflects petiole length. The term 'white clover' is applied to the species in general, 'Dutch clover' is often applied to intermediate varieties, and 'ladino clover' is applied to large varieties.
Phoebis sennae, the cloudless sulphur, is a mid-sized butterfly in the family Pieridae found in the Americas. There are several similar species such as the yellow angled-sulphur, which has angled wings, statira sulphur, and other sulphurs, which are much smaller. The species name comes from the genus Senna to which many of the larval host plants belong.
Trifolium stoloniferum, the running buffalo clover, is an endangered species of perennial clover native to the eastern and midwestern United States. From 1940 to 1985 it was believed to be extinct until two populations were discovered in West Virginia. Since then, more populations have been found in the US but it still remains one of the most imperiled plants in North America.
Trifolium pratense, red clover, is a herbaceous species of flowering plant in the bean family Fabaceae, native to Europe, Western Asia, and northwest Africa, but planted and naturalized in many other regions.
Trifolium subterraneum, the subterranean clover, subterranean trefoil, is a species of clover native to Europe, Southwest Asia, Northwest Africa and Macaronesia. The plant's name comes from its underground seed development (geocarpy), a characteristic not possessed by other clovers.
The Chemin du Roy is a historic road along the north shore of the St. Lawrence River in Quebec. The road begins in Repentigny and extends almost 280 kilometres (170 mi) eastward towards Quebec City, its eastern terminus. Most of the Chemin du Roy today follows along the present-day Quebec Route 138. The modern expressway that replaces both Route 138 and the Chemin du Roy through most of its course is Quebec Autoroute 40.
Trifolium amoenum, known by the common names showy Indian clover and two-fork clover, is endemic to California, and is an endangered annual herb that subsists in grassland areas of the San Francisco Bay Area and the northern California Coast Ranges.
Trifolium dubium, the lesser trefoil, suckling clover, little hop clover or lesser hop trefoil, is a flowering plant in the pea and clover family Fabaceae. This species is generally accepted as the primary plant to represent the traditional Irish shamrock.
Trifolium medium, the zigzag clover, is a flowering plant species in the bean family Fabaceae. It is similar in appearance to red clover, Trifolium pratense, but the leaflets are narrower and have no white markings and the narrow stipules are not bristle-pointed. The species is native to Europe from Britain to the Caucasus.
The wildlife of Morocco is composed of its flora and fauna. The country has a wide range of terrains and climate types and a correspondingly large diversity of plants and animals. The coastal areas have a Mediterranean climate and vegetation while inland the Atlas Mountains is forested. Further south, the borders of the Sahara Desert are increasingly arid. Large mammals are not particularly abundant in Morocco, but rodents, bats, and other small mammals are more plentiful. Four hundred and ninety species of birds have been recorded here.
Zerene cesonia, the southern dogface, is a North and South American butterfly in the family Pieridae, subfamily Coliadinae.
Trifolium bolanderi is a species of clover known by the common names Bolander's clover and parasol clover.
Trifolium breweri, which has the common names forest clover and Brewer's clover, is a perennial clover that is native to mixed evergreen forests and coastal coniferous forests in Southern Oregon and California.
Trifolium lemmonii is a species of clover known by the common name Lemmon's clover.
