See text. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its The Laurales are an order of Flowering plants They are a basal group of Dicots related to and formerly sometimes included in the Magnoliales. The Lauraceae or Laurel family comprises a group of Flowering plants included in the order Laurales. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank.

Persea is a genus of about 150 species of evergreen trees belonging to the laurel family, Lauraceae. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic In Botany, an Evergreen plant is a plant having leaves all year round A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or The Lauraceae or Laurel family comprises a group of Flowering plants included in the order Laurales. The best-known member of the genus is the Avocado P. The avocado ( Persea americana) (from Nahuatl āhuacatl) also known as aguacate ( Spanish) butter pear or americana, widely cultivated in subtropical regions for its large, edible fruit. The term fruit has different meanings dependent on context and the term is not synonymous in Food preparation and Biology.

They are medium-size trees, 15-30 m tall at maturity. The leaves are simple, lanceolate to broad lanceolate, varying with species from 5-30 cm long and 2-12 cm broad, and arranged spirally or alternately on the stems. In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. The flowers are in short panicles, with six small greenish-yellow perianth segments 3-6 mm long, nine stamens and an ovary with a single embryo. A flower, also known as a bloom or Blossom, is the reproductive structure found in Flowering plants (plants of the division Magnoliophyta, also The fruit is an oval or pear-shaped drupe, with a fleshy outer covering surrounding the single seed; size is very variable between the species, from 1-1. The term fruit has different meanings dependent on context and the term is not synonymous in Food preparation and Biology. In Botany, a drupe is a Fruit in which an outer fleshy part ( Exocarp, or skin and Mesocarp, or flesh surrounds a shell (the pit A seed (in some plants referred to as a kernel) is a small embryonic Plant enclosed in a covering called the seed coat usually with some stored 5 cm in e. g. P. borbonia and P. indica, up to 10-20 cm in P. americana.

The species of Persea have a disjunct distribution, with about 70 Neotropic species, ranging from Brazil and Chile in South America to Central America and Mexico, the West Indies, and the southeastern United States; a single species, P.

Fossil evidence indicates that the genus originated in West Africa during the Paleocene, and spread to Asia, to South America, and to Europe and thence to North America. West Africa or Western Africa is the Westernmost Region of the African Continent. The Paleocene or Palaeocene, "early dawn of the recent" is a geologic epoch that lasted from 65 It is thought that the gradual drying of Africa, west Asia, and the Mediterranean from the Oligocene to the Pleistocene, and the glaciation of Europe during the Pleistocene, caused the extinction of the genus across these regions, resulting in the present distribution. The Oligocene is a geologic epoch of the Paleogene period and extends from about 33 The Pleistocene ('plaɪstəsin is the epoch from 18 million to 10000 years BP covering the world's recent period "Glacial" and "Glaciation" redirect here For the geological periods see Glacial period.

Persea species are used as food plants by the larvae of some Lepidoptera species including Giant Leopard Moth, Coleophora octagonella (feeds exclusively on P.

The Giant Leopard Moth or Eyed Tiger Moth ( Hypercompe scribonia) is a Moth of the family Arctiidae. Coleophora is a very large genus of Moths of the family Coleophoridae with around 1000 described species carolinensis) and Hypercompe indecisa. Hypercompe is a Genus of Moths of the family Arctiidae. There are over 80 Species found throughout the Americas

Classification

The genus Persea is treated in three subgenera. The Asian subgenus Machilus is treated in a separate genus Machilus by many authors, including in the Flora of China, while graft-incompatibility between subgenus Persea and subgenus Eriodaphne suggests that these too may be better treated as distinct genera, in fact Kostermans (1993) founded the genus Mutisiopersea for these. Dr André Joseph Guillaume Henri 'Doc' Kostermans ( 1 July, 1906 — 10 July, 1994) was a Botanist. Another closely related genus Beilschmiedia is also sometimes included in Persea.
