Appearance and leaves

There are usually persistent, sometimes one or two year, herbaceous plants , rarely half-shrubs , shrubs or trees . Some species are xerophytes . They often form rhizomes as persistence organs.

Often the leaves are sometimes in basal rosettes (basal leaves) and / or mostly alternate, rarely opposite or arranged in whorls on the stem (stem leaves) . The leaves are mostly stalked or rarely sessile. The leaf blades are simple or pinnate. The leaf edges can be smooth or serrated. Especially in xerophytic species, the blades are dotted with glands. There are no stipules .

Inflorescences and flowers

The basket-shaped part inflorescences are rarely individually, usually several to many in mostly schirmtraubigen , rare in traubigen , ährigen , rispigen total inflorescences together. The flower heads are pseudanthia , so they have an ecological effect like “ flowers ”. In Baccharis , the flower heads are disc-shaped and homogeneous: all flowers are hermaphroditic. In all other genera of this tribe, the inflorescences are disc-shaped or radial and heterogamous: they contain hermaphroditic and functionally unisexual flowers. The usually spiral or sometimes in three to five or more rows, free, durable or early sloping bracts are uneven, herbaceous, paper-like to dry-skinned or have dry-skinned edges and / or tips. Sometimes the bracts are in one or two rows and are only slightly uneven, herbaceous with barely to clearly dry-skinned edges and / or tips. The mostly flat to conical, sometimes concave cup bottoms usually have no chaff leaves . Chaff leaves are only present in Eastwoodia and Rigiopappus .

The flower baskets contain a single-row (sometimes two- to multi-row) wreath of ray- flowers (also called ray-flowers) or have no ray-flowers and always tubular flowers (also called disc-shaped flowers). The ray florets are mostly functionally male, rarely functionally female or sterile. The color spectrum of the petals of the ray florets includes white, pink, red, blue and purple, or often yellow. For example, with some Conyza species, the tongues are greatly reduced. The tubular flowers are mostly hermaphroditic and fertile, rarely functionally male , for example in Benitoa . The color spectrum of the petals of the tubular flowers includes white, pink, red, blue and purple, or often yellow. The tubular flowers are always radial symmetry with mostly five, rarely four crown teeth. The anthers have a blunt or rounded, not tailed base and mostly triangular to linear appendages at their upper end; appendages are seldom missing. The stylus with two linear stylus branches are bare and smooth or papilose on the underside and the top has two lines with scar tissue from their base to their tip or on the appendages; the appendages are mostly delta-shaped to lanceolate.

fruit

The achenes of a flower head can all be the same (monomorphic) or there are two different types ( heterocarpy , dimorphic). The achenes are more or less columnar to prismatic and five-ribbed or sometimes flattened and two-ribbed; sometimes they are beaked. The surface of the achenes is smooth, prickly or wrinkled and glabrous or hairy, then often with glandular hairs. There is usually a durable pappus , which consists of rarely one, usually two to three or more rows of mostly bearded bristles, rarely of scales that are sometimes covered with awn; very rarely it is both scales and bristles or awns. The units of distribution ( diaspores ) are the achenes with their pappus.

Systematics and distribution

The tribe Astereae has an almost worldwide distribution. They mainly thrive in the temperate latitudes. In North America there are about 77 genera with about 719 species.

The Tribus Astereae was drawn up in 1819 by Alexandre Henri Gabriel de Cassini in Journal de Physique, de Chimie, d'Histoire Naturelle et des Arts , 88, p. 195. The name of the type genus Aster L. is derived from the Latin word astrum for star, celestial body and refers to the radial arrangement of the ray or ray flowers in the flower head. The Astereae tribe was reorganized in the works of K. Bremer 1994, GL Nesom 1994, 2000 and Richard D. Noyes & Loren H. Rieseberg 1999.
