Astereae

(Tribe)

Overview

[ Back to top ]

Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs and trees. Plants within the tribe are present nearly worldwide divided into 170 genera and more than 2,800 species. They are found primarily in temperate regions of the world.1]

The taxonomy of the tribe Astereae has been dramatically changed after both morphologic and molecular evidence suggested that large genera such as Aster, as well as many others, needed to be separated into several genera or shifted to better reflect the plants' relationships. A paper by R. D. Noyes and L. H. Rieseberg[2] showed that most of the genera within the tribe in North America actually belong to a single clade, meaning they have a common ancestor. This is referred to as the North American clade. and Harold E. Robinson have been two of the most important taxonomists involved in the recent work and are continuing to re-categorise the genera within the tribe worldwide.[1]

G. robusta, found in the western states, is a coastal scrub bush that is reputed to have several medicinal uses. Hairy gumweed, Grindelia cuneifolia, occurs in brackish coastal marshes of western North America, such as in some portions of the San Francisco Bay perimeter. [more]

    Homochroma

    Hosta

    Hosta (, syn.: Funkia) is a genus of about 23?45 species of lily-like plants in the family Asparagaceae, subfamily Agavoideae, native to northeast Asia. They have been placed in their own family, Hostaceae (or Funkiaceae); like many 'lilioid monocots', they were once classified in the Liliaceae. The scientific name is also used as the common name; in the past they were also sometimes called the Corfu Lily, the Day Lily, or the Plantain lily, but these terms are now obsolete. The name Hosta is in honor of the Austrian botanist Nicholas Thomas Host. The Japanese name Giboshi is also used in English to a small extent. The rejected generic name Funkia, also used as a common name, can be found in some older literature. [more]

    Juniperus

    Junipers are coniferous plants in the genus Juniperus () of the cypress family Cupressaceae. Depending on taxonomic viewpoint, there are between 50-67 species of juniper, widely distributed throughout the northern hemisphere, from the Arctic, south to tropical Africa in the Old World, and to the mountains of Central America. [more]

    Lachnophyllum

    Lagenifera

    [more]

    Lagenophora

    [more]

    Libanotis

    Herbs rarely subshrubs, perennial, stout, sometimes small, rarely acaulescent. Taproot conic, unbranched, caudex simple, rarely branched, woody. Stem often strongly angled and fluted, base densely clothed with fibrous leaf remains. Basal leaves 1-4-pinnate or 1-4-pinnatisect; ultimate segments linear, ovate or lanceolate, entire or lobed. Umbels compound, terminal and lateral; bracts few to numerous or absent; rays numerous to few; bracteoles several, linear or lanceolate. Calyx teeth conspicuous, linear, triangular or elliptic. Petals white, rarely pinkish, ovate or obcordate, apex narrow, inflexed. Stylopodium low-conic, margins often undulate at the base. Fruit ovoid or oblong, slightly to moderately dorsally compressed; dorsal ribs filiform, low or prominent, acute-ridged, lateral ribs sometimes slightly broader; vittae 1-2(-3) in each furrow, 2-4 (rarely 6-8) on commissure. Seed face plane. Carpophore entire or 2-parted.[2] [more]

    Loranthus

    Loranthus is a genus of mostly parasitic plants that grow on the branches of woody trees. It belongs to the family Loranthaceae, the showy mistletoe family. In most earlier systematic treatments it contains all mistletoe species with bisexual flowers, though some species have reversed to unisexual flowers, while most modern systematists treat it as a monotypic genus with the only species Loranthus europaeus Jacq. - the summer mistletoe or European yellow mistletoe. In contrast to the wellknown European or Christmas mistletoe (Viscum album L., Santalaceae or Viscaceae) this species is deciduous. The systematic situation of Loranthus is not entirely clear, and some showy mistletoes in Asia may be true parts of this genus. [more]

    Machaeranthera

    Machaeranthera is a genus of flowering plants in the daisy family which are known by the common name tansyaster. Tansyasters are variable in appearance. Some are small singular wildflowers while others are sprawling shrubs. Several species easily hybridize with each other as well, making identification difficult. In general, members of the genus may be identified by the sharp-pointed, dagger-shaped anthers in the disc florets at the center of the flower. The flower heads are usually daisylike and are usually a shade of purple or blue, but may be pink, yellow, or white. Tansyasters are native to western North America. [more]

    Melanodendron

    Melanodendron integrifolium (Black Cabbage Tree) is one of the endemic trees in the Asteraceae family from the island of Saint Helena (South Atlantic Ocean).

Phyllaries 30-45 in 2-3 series, (reflexed in fruit) 1-nerved (flat), oblong or lanceolate to linear, equal or unequal, herbaceous, bases usually indurate, margins scarious, herbaceous faces stipitate-glandular. Receptacles flat to convex, pitted to verrucose, epaleate. Ray florets 10-70, pistillate, fertile; corollas white to blue or purple (tightly coiled at maturity). Disc florets 15-150, bisexual, fertile (pappose) ; corollas yellow, lobes often purple, tubes shorter than funnelform throats, lobes 5, erect, deltate to lanceolate (glabrous or sparsely appressed-hairy). Cypselae: of ray fusiform to obovoid, of disc fusiform to clavate or obovoid, compressed, 5-18-nerved, faces sparsely to densely appressed-hairy (disc glabrate or glabrous in P. heterocarpa) ; pappi: ray 0; disc persistent, of 20-50, white to tawny, unequal, barbellate, apically attenuate bristles in 1-2 series. x = 3, 4, 9.[4] [more]

    Scurrula

    Shrubs parasitic, base often with epicortical roots, most young parts usually with dense stellate and sometimes also verticillate hairs. Leaves opposite or subopposite, pinnately veined.

Calyx pyriform or turbinate, base attenuate, limb annular, persistent. Mature flower bud tubular. Corolla sympetalous, curved, basal portion inflated, split along 1 side at anthesis, tip ellipsoid or ovoid, lobes all reflexed toward the side away from the split. Stamens inserted at base of corolla lobes; filaments short; anthers 4-loculed, sometimes multilocellate. Pollen grain trilobate in polar view. Ovary 1-loculed; placentation basal. Style filiform, 4-angled; stigma only slightly enlarged and capitate. Berry turbinate, clavate, or pyriform, base narrow or often attenuate into stipe, exocarp leathery, pubescent or glabrous.[5] [more]

    Symphyotrichum

    Symphyotrichum is a genus of about 90 species of herbaceous annual and perennial plants in the composite family (Asteraceae) that were formerly treated within the genus Aster. The majority are endemic in North America, but several species also occur in the West Indies, Central and South America, as well as in eastern Eurasia. Furthermore, many species have been introduced to Europe as garden specimens, most notably the New England aster (Symphyotrichum novae-angliae) and the New York aster (Symphyotrichum novi-belgii).

    Taxillus

    Shrubs parasitic, most young parts usually with dense stellate and/or verticillate hairs, rarely glabrous (in T. delavayi). Leaves opposite or alternate, pinnately veined. Inflorescences axillary, umbels or rarely short, irregular racemes, 2-5-flowered; 1 bract subtending each flower, usually scale-like. Flowers bisexual, 4[or 5]-merous, zygomorphic. Calyx ellipsoid or ovoid, rarely subglobose, base not attenuate, limb annular, entire or denticulate, persistent. Mature flower bud tubular, tip ellipsoid or ovoid. Corolla sympetalous, slightly curved, basal portion ± inflated, split along 1 side at anthesis, lobes all reflexed toward the side away from the split. Stamens inserted at base of corolla lobes; filaments short to almost absent; anthers 4-loculed, sometimes multilocellate. Pollen grain trilobate or semilobate in polar view. Ovary 1-loculed; placentation basal. Style filiform, 4- or 5-angled; stigma usually capitate. Berry ellipsoid or ovoid, rarely globose, exocarp leathery, verrucose or granular, rarely smooth, pubescent or glabrous, base rounded.[6] [more]
