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 Asterales are an order of Dicotyledonous Flowering plants which include the composite family Asteraceae ( Sunflowers daisies The family Asteraceae or Compositae (known as the aster, daisy, or sunflower family) is the largest family of Flowering Count Alexandre Henri Gabriel de Cassini (1781-1832 was a French Botanist and naturalist, who specialised in the sunflower family ( Asteraceae) (then known Biodiversity is the variation of Life forms within a given Ecosystem, Biome or for the entire Earth.

The tribe Heliantheae is the most familiar tribe of the sunflower family (Asteraceae). The sunflower ( Helianthus annuus) is an Annual plant in the family Asteraceae and native to the Americas, with a large flowering The family Asteraceae or Compositae (known as the aster, daisy, or sunflower family) is the largest family of Flowering The name is derived from the genus Helianthus, which is Latin for sun flower. The Helianthus L Genus comprises 67 species and several subspecies in the Asteraceae family all of which are native to North America Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. The Heliantheae is the third largest tribe in the sunflower family, with some 190 genera and nearly 2500 recognized species. Only the tribes Senecioneae and Astereae are larger. Senecioneae is the largest tribe of the Asteraceae, or the sunflower family comprising approximately 150 genera and 3000 species Astereae is a tribe of plants in the family Asteraceae that includes annuals biennials perennials subshrubs shrubs and trees Most genera and species are found in North America and South America, particularly in Mexico. South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a The United Mexican States ( or commonly Mexico (ˈmɛksɪkoʊ () is a federal constitutional Republic in North America. A few genera are pantropical.

Most Heliantheae are herbs or shrubs, but there are some that grow to the size of small trees. A shrub or Bush is a horticultural rather than strictly botanical category of Woody plant, distinguished from a Tree Leaves are usually hairy and arranged in opposite pairs. Trichomes, from the Greek meaning "growth of Hair " are fine outgrowths or appendages on Plants and certain Protists These are of diverse The anthers are usually blackened. The stamen ( Plural stamina or stamens, from Latin stamen meaning "thread of the warp " is the male

Uses

Commercially important plants in the Heliantheae include sunflower and jerusalem artichoke. The sunflower ( Helianthus annuus) is an Annual plant in the family Asteraceae and native to the Americas, with a large flowering The Jerusalem artichoke ( Helianthus tuberosus) also called the sunroot or sunchoke or earth apple or topinambur, is a species Many garden flowers are also in this group, such as Coreopsis, Cosmos, Echinacea, Rudbeckia, and Zinnia. Tickseed is the Common name for Coreopsis, a group of 35 species of herbs in the family Asteraceae and genus Coreopsis. Cosmos is a Genus of about 20-26 Species of annual and perennial Plants in the family Asteraceae, native Echinacea, commonly called Purple Coneflower, is a genus of nine species of Herbaceous plants in the family Asteraceae. Rudbeckia is one of at least four genera within the Flowering plant family Asteraceae whose members are commonly known as Coneflowers Zinnia is a Genus of 20 species of annual and perennial Plants of family Asteraceae, originally from scrub and dry

In addition to the benefits brought by the group, there are also problematic weeds. WEED (1390 AM) is a Radio station broadcasting a Spanish format Species of Ambrosia (ragweed) produce large quantities of pollen. Ragweeds ( Ambrosia) also called bitterweeds and bloodweeds, are a Genus of flowering Plants from the sunflower Pollen is a fine to coarse powder consisting of microgametophytes ( pollen grains) which produce the male Gametes (sperm cells of Each plant is reputed to be able to produce about a billion grains of pollen over a season, and the plant is wind-pollinated. Pollination in angiosperms and Gymnosperms is the process that transfers pollen grains, which contain the male Gametes (sperm to where the female It is highly allergenic, as the greatest pollen allergen of all pollens, and the prime cause of hayfever. An allergen is a nonparasitic Antigen capable of stimulating a Type-I hypersensitivity reaction in atopic individuals Hay Fever is a comic play written by Noel Coward in 1924 and first produced in 1925 with Marie Tempest as the first Judith Bliss

Subtribes and representative genera

The traditional circumscription of the Heliantheae arises from Cassini's 19th century classification of the Asteraceae. Count Alexandre Henri Gabriel de Cassini (1781-1832 was a French Botanist and naturalist, who specialised in the sunflower family ( Asteraceae) (then known This broad Heliantheae has been divided by some authors into smaller tribes: Bahieae, Chaenactideae, Coreopsideae, Helenieae, Heliantheae sensu stricta, Madieae, Millereae, Perityleae, Polymnieae, and Tageteae. Sensu is a Latin term meaning "in the sense of"It is used in fields including biology geology and law in the phrases sensu stricto Tageteae is a tribe of the Plant family Asteraceae. It consists of approximately 216 species divided among 28 genera The Heliantheae is closely related to the Eupatorieae, although the precise relationships are a matter of ongoing research. Eupatorieae is a tribe of over 2000 Within the aster family, the Eupatorieae are nested within what has traditionally been the Heliantheae (broadly [1]

In his 1981 revision of the Heliantheae, Harold Ernest Robinson divided the group into 35 subtribes:
