The order Asterales currently includes eleven families, the largest of which are the Asteraceae, with about 25, 000 species, and the Campanulaceae (" Bellflowers "), with about 2, 000 species.

The core Asterales are Stylidiaceae ( 6 genera ), APA clade ( Alseuosmiaceae, Phellinaceae and Argophyllaceae ( 7 genera )) and MGCA clade ( Menyanthaceae, Goodeniaceae, Calyceraceae-total 20 genera ), and Asteraceae ( 1600 genera ).

All Asterales families are represented in the southern hemisphere ; however Asteraceae and Campanulaceae are cosmopolitan and Menyanthaceae nearly so.

Although most extant species of Asteraceae are herbaceous, the examination of the basal members in the family suggests that the common ancestor of the family was an arborescent plant, a tree or shrub, perhaps adapted to dry conditions, radiating from South America.

An Oligocene ( 34 – 23 Mya ) pollen is known for Asteraceae and Goodeniaceae, and seeds from Oligocene and Miocene ( 23 – 5. 3 Mya ) are known for Menyanthaceae and Campanulaceae respectively.

Of horticultural importance are many of the Asteraceae ( e. g. chrysanthemum ) and Campanulaceae.

Asteraceae or Compositae ( commonly referred to as the aster, daisy, or sunflower family ), are an exceedingly large and widespread family of Angiospermae.

Most members of Asteraceae are herbaceous, but a significant number are also shrubs, vines and trees.

Asteraceae have a cosmopolitan distribution, and are found everywhere except Antarctica and the extreme Arctic.

Two large plant families that he first recognized are still in use today: the Asteraceae and Brassicaceae.

If many bracts are present and they are strictly connected to the stem, like in the family Asteraceae, the bracts might collectively be called an involucre.

In some plant families, genera with apomixis are quite common, e. g. in Asteraceae, Poaceae, and Rosaceae.

Tragopogon, also known as salsify or goatsbeard, is a genus of flowering plants in the sunflower family Asteraceae that has over 140 species, including the vegetable known as salsify, as well as a number of common wild flowers, some of which are usually regarded as weeds.

: Other examples for sometimes well known plant names with zoological equivalents are Aotus ( Fabaceae and Mammalia ), Arenaria ( Caryophyllaeceae and Aves ), Betula ( Betulaceae and Hymenoptera ), Chloris ( Cactaceae and Aves ), Dugesia ( Asteraceae and Plathelminthes ), Erica ( Ericaceae and Araneae ), Hystrix ( Poaceae and Mammalia ), Iris ( Asparagales and Orthoptera ), Liparis ( Orchidaceae and Actinopterygii ), Phalaenopsis ( Asparagales and Aves ), Pinus ( Pinaceae and Mollusca ), Prunella ( Lamiaceae and Aves ), Ricinus ( Fabaceae and Acari ), Taxus ( Taxaceae and Mammalia ), Typha ( Typhaceae and Porifera ), Ulva ( Ulvophyceae and Lepidoptera ), Viola ( Violaceae and Lepidoptera ).

* synandrous: only the anthers are connate ( such as in the Asteraceae )

The paleae ( chaffs on the receptacles of many Asteraceae ) have orange to reddish purple ends, and are longer than the disc corollas.

Like all Asteraceae, the flowering structure is a composite inflorescence, with purple ( rarely yellow or white ) florets arranged in a prominent, somewhat cone-shaped head – " cone-shaped " because the petals of the outer ray florets tend to point downward ( are reflexed ) once the flower head opens, thus forming a cone.

Both genera are members of the daisy ( or aster ) family, Asteraceae.

Flowers such as Polypodiaceae s. l., Araceae, Poaceae, Asteraceae, Piperaceae, and Orchidaceae are also present in the region.

Most of its diet is vegetable, round and fleshy leaves from Caryophyllaceae, Asteraceae, and cruciferous vegetables taken from open fields or gardens and lawns ; young shoots and seedlings are favoured, and it will take grain, pine nuts, and certain fruits and berries.

They resemble small Osmia, but they are oligolectic ( specialized on a few subfamilies of Asteraceae ) and use resin from conifers, as well as plant fibers and sand, as cell wall material.

Asteraceae is an economically important family.

For example, ITS has proven especially useful for elucidating relationships among congeneric species and closely related genera in Asteraceae ( Baldwin, 1992 ; Baldwin et al., 1995 ; Kim et al., 1996 ) as well as clinically important yeast species.

The Asterales, by dint of being a super-set of the family Asteraceae, include some species grown for food, including the sunflower ( Helianthus annuus ), lettuce ( Lactuca sativa ) and chicory ( Cichorium ).

Plants including the common name " chamomile ", of the family Asteraceae, include:

However, depending on the locality and the aspects under discussion, several other families have equal claim to being characteristic, including Rutaceae, Rhamnaceae, Fabaceae, Asteraceae, Geraniaceae, and Iridaceae.

The name ivy has also been used as a common name for a number of other unrelated plants, including Boston ivy ( Japanese Creeper Parthenocissus tricuspidata, in the family Vitaceae ), Cape-ivy or German-ivy ( Delairea odorata in the family Asteraceae ), poison-ivy ( Toxicodendron radicans in the family Anacardiaceae ), and Swedish ivy ( Whorled Plectranthus Plectranthus verticillatus, in the family Lamiaceae ).

Unlike most tubers, but in common with other members of the Asteraceae ( including the artichoke ), the tubers store the carbohydrate inulin ( not to be confused with insulin ) instead of starch.

Everlastings ( or Everlasting Daisies, or Paper Daisies ), species in a group of genera in the family Asteraceae, including ;

Crimson Rosellas forage in trees, bushes, and on the ground for the fruit, seeds, nectar, berries, and nuts of a wide variety of plants, including members of the Myrtaceae, Asteraceae, and Rosaceae families.

It feeds on a variety of plants including ones from the Asteraceae family, its main source of nutrition, but other families of plants that the butterfly may feed on include thistles, asters, yarrow, and pearly everlasting.

Grindelia is a genus of plants native to the Americas belonging to the family Asteraceae, ( Compositae ).

( Narrow-leaved purple coneflower, blacksamson echinacea ) is a herbaceous plant species in Asteraceae.

Achillea millefolium ( yarrow ( or common yarrow ) is a flowering plant in the family Asteraceae, which is grown in temperate regions of the Northern Hemisphere.

The Asteraceae may represent as much as 10 % of autochthon flora in many regions of the world.

In botany, chaff refers to the thin receptacular bracts of many species in the sunflower family Asteraceae and related families.

Tanacetum is a genus of about 160 species of flowering plant in the family Asteraceae, native to many regions of the Northern Hemisphere.

Adults feed on the nectar of many species of flowers, mostly from those of the Apocynaceae, Asteraceae, and Fabaceae families.

Unlike many other members of the family Asteraceae, whose seeds are airborne with a plume of silky hairs resembling miniature parachutes, cocklebur seeds are produced in a hard, spiny, globose or oval double-chambered, single-seeded bur. 32 -. 79 in long.

An involucre is a common feature beneath the inflorescences of many Apiaceae, Asteraceae, Dipsacaceae and Polygonaceae.

The genus is one of many in the Asteraceae that are known as sunflowers.

He has written over 650 publications, mainly on the Asteraceae, mosses ( Bryophyta ), Marchantiophyta, and the long-legged fly family Dolichopodidae ( describing over 200 new species and 6 new genera, such as Harmstonia and Nanomyina ) and many other subjects.

He named many flowering plants and new genera in the sunflower family ( Asteraceae ), many of them from North America.
