Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more te ...

Famatinanthoideae
''Famatinanthus'' is a genus in the family Asteraceae that was described in 2014 and has been assigned to its own tribe Famatinantheae and subfamily Famatinanthoideae. It contains only one known species, ''F. decussatus'', a small shrub of ½—1¾ m (1⅔–5¾ ft) high that is an endemic of the Andes of north-western Argentina, with small, entire, oppositely set leaves and flowerheads containing about ten cream-colored, ray and disk florets, with backward coiled lobes. It is locally known as sacansa. For more than 100 years, the species was known to science only from the type collection. It was described in 1885 and originally assigned to the genus ''Aphyllocladus''. Description ''Famatinanthus'' is a long-lived, xerophitic, thornless shrub of ½—1¾ m high. Flowers can be found from December to February. It has fifty four chromosomes (2n=54), probably developed through multiplication of a base set of nine (n=9).

Hecastocleidoideae
''Hecastocleis'' is a genus of low thorny shrubs with stiff branches, assigned to the daisy family. At the tip of each of the branches, inflorescences are subtended by oval, thorny, whitish to greenish bracts that enclose several flower heads which each contain only one pinkish bud, opening into a white corolla. It contains but one species, ''Hecastocleis shockleyi'', the only representative of the tribe Hecastocleideae, and of the subfamily Hecastocleidoideae. Its vernacular name is prickleleaf. It is confined to the southwestern United States. and Description ''Hecastocleis shockleyi'' is a xerophytic thorny shrub of , occasionally 1½ m (4 ft 11 in) high. It has sixteen chromosomes (2n=16). Leaves The leaves are alternately set along the branches. The leaf blades are hairless or with a few soft hairs, slightly olive green, stiff and leathery, with three main veins, linear to narrowly ovate in shape, long, their base approximately clasping the branch, with ...

Asteroideae
Asteroideae is a subfamily of the plant family Asteraceae. It contains about 70% of the species of the family. It consists of several tribes, including Astereae, Calenduleae, Eupatorieae, Gnaphalieae, Heliantheae, Senecioneae and Tageteae. Asteroideae contains plants found all over the world, many of which are shrubby. There are about 1,135 genera and 17,200 species within this subfamily; the largest genera by number of species are '' Helichrysum'' (500–600) and '' Artemisia'' (550). Asteroideae is said to date back to approximately 46–36.5 million years ago. Common characteristics This family will often have radiate style heads but some could have discoid or disciform. They contain ray florets that are three lobed and are also considered perfect flower implying that it is bisexual. Many contain stigmatic surfaces that are separated by two marginal bands and terminal sterile appendages with sweeping hairs. Taxonomy This subfamily is composed of 21 tribes that are broke ...

Stifftioideae
The Stifftioideae are a subfamily of the family Asteraceae family of flowering plants. It comprises a single tribe, Stifftieae, of ten genera. These plants are vines, shrubs or small trees with thin to leathery, hairless of felty haired leaves with leaf stalks and entire margins, set alternately or rarely oppositely along the branches. The flower heads are at the tip of the branches or rarely in the axils of the leaves, on their own or in open to tightly packed cymes. The involucre may be narrowly cylindrical to half globular, and consists of at least three whorls of overlapping and gradually changing bracts. The common base of the florets (or receptacle) does not carry a bract (or palea) subtending each floret. The florets are all bisexual and may have either a ligulate corolla, a disk corolla, or a bilabiate corolla (three lobes merged to a strap with teeth at the tip and two lobes free much further down), and the lobes may be strongly coiled. The corolla can be yellow, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vicki Ann Funk
Vicki Ann Funk (November 26, 1947 – October 22, 2019) was an American botanist and curator at the Smithsonian's National Museum of Natural History, known for her work on members of the composite family (Asteraceae) including collecting plants in many parts of the world, as well as her synthetic work on phylogenetics and biogeography. Biography Funk was born on November 26, 1947, in Owensboro, Kentucky, to Edwin Joseph and Betty Ann (''née'' Massenburg) Funk. She had two brothers, Edwin Jr. and Jared Kirk. She grew up in Owensboro and at a few United States Air Force bases before she was in elementary school. Funk studied biology and history at Murray State University in Kentucky and received a Bachelor of Science (BS) degree in 1969. She had wanted to attend medical school, but decided against it after volunteering at a hospital one summer. After graduating, she lived and worked part-time in Germany for two years, then returned to the United States to teach high school for ...

Cichorioideae
The Cichorioideae are a subfamily of the family Asteraceae of flowering plants. Familiar members of Cichorioideae include lettuce, dandelions, chicory and '' Gazania'' species. The subfamily comprises about 240 genera and about 2900 species. It is heterogeneous and hard to characterize except with molecular characters. Taxonomy The subfamily as understood in 1998 turned out to be paraphyletic, based on studies of DNA sequences, so a number of tribes were moved to new subfamilies. Names for the new subfamilies were published in 2002. In 2004, 2007, and 2008, molecular phylogenetic studies further clarified relationships within Cichorioideae.Sterling C. Keeley, Zac H. Forsman, and Raymund Chan. 2007.

Corymbioideae
''Corymbium'' is a genus of flowering plants in the Asteraceae, daisy family comprising nine species. It is the only genus in the subfamily Corymbioideae and the tribe Corymbieae. The species have leaves with parallel veins, strongly reminiscent of monocots, in a rosette and compounded inflorescences may be compact or loosely composed racemes, panicles or corymbs. Remarkable for species in the daisy family, each flower head contains just one, bisexual, mauve, pink or white disc floret within a sheath consisting of just two large involucral bracts. The species are all endemism, endemic to the Cape Floristic Region of South Africa, where they are known as plampers. Description The species of ''Corymbium'' are monoecious, Glossary of botanical terms#acaulescent, stemless, Perennial plant, perennial, herbaceous plants of high, that grow in tufts and look like a monocotyledon as long as they are not flowering. The plants have a fibrous rhizome that is covered the persisting bases o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aster (genus)
''Aster'' is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 170 species, all but one of which are restricted to Eurasia; many species formerly in ''Aster'' are now in other genera of the tribe Astereae. ''Aster amellus'' is the type species of the genus and the family Asteraceae. The name ''Aster'' comes from the Ancient Greek word (''astḗr''), meaning "star", referring to the shape of the flower head. Many species and a variety of hybrids and varieties are popular as garden plants because of their attractive and colourful flowers. 'Aster' species are used as food plants by the larvae of a number of Lepidoptera species—see list of Lepidoptera that feed on ''Aster''. Asters can grow in all hardiness zones. Circumscription The genus ''Aster'' once contained nearly 600 species in Eurasia and North America, but after morphologic and molecular research on the genus during the 1990s, it ...

Wunderlichioideae
The Wunderlichioideae are a subfamily of flowering plants belonging to the family Asteraceae. The subfamily includes eight genera and about 24 species that are concentrated in Brazil (''Wunderlichia'') and Guyana (''Chimantaea'', ''Stenopadus'', and ''Stomatochaeta''), with some species in other South America countries (''Hyalis'' and ''Ianthopappus'') and others (''Nouelia'' and '' Leucomeris'') in Southeast Asia and the Himalayas.Panero, J. L., and V. A. FunkThe value of sampling anomalous taxa in phylogenetic studies: major clades of the Asteraceae revealed.Mol. Phylogenet. Evol. 2008; 47: 757-782. Distinguishing features of the members of this subfamily are presence of styles with glabrous style branches and a deletion in the ''rpoB'' gene.

Barnadesioideae
Barnadesioideae is a subfamily of flowering plants in the aster family, Asteraceae. It comprises a single tribe, the Barnadesieae. The subfamily is endemic to South America. Molecular evidence suggests it is a basal clade within the family,Timme, R. E., et al. (2007)A comparative analysis of the ''Lactuca'' and ''Helianthus'' (Asteraceae) plastid genomes: identification of divergent regions and categorization of shared repeats.''American Journal of Botany'' 94(3) 302–12. and it is monophyletic.

Carduoideae
Carduoideae is the thistle subfamily of the Asteraceae, or sunflower family, of flowering plants. It comprises a number of tribes in various circumscriptions of the family, in addition to the Cynareae. Takhtajan, according to Reveal, includes 10 tribes in addition to the Cynareae: the Arctotideae, the Barnadesieae, the Carlineae, the Cichorieae, the Echinopseae, the Eremothamneae, the Gundelieae, the Liabeae, the Mutisieae, and the Vernonieae. Of these 11, Thorne agrees with seven in his eight-tribe taxonomy of the Carduoideae, placing the tribes Cardueae (Cynareae), plus Arctotideae, Cichorieae, Eremothamneae, Liabeae, Mutisieae, and Vernonieaes in the subfamily, plus the Tarchonantheae. The Panero and Funk classification of 2002 (a molecular phylogenetic classification based upon chloroplast genes) places just three tribes in the subfamily: the Cynareae, plus the Dicomeae (created by Panero and Funk's paper, consisting of ''Dicoma'', '' Erythrocephalum'', ''Gladiop ...

Gymnarrhenoideae
Gymnarrhenoideae is a subfamily with in the family Asteraceae, with only one tribe, the Gymnarrheneae. Two very different species have been assigned to it, ''Gymnarrhena micrantha'', a winter annual from the deserts of North-Africa and the Middle-East, and ''Cavea tanguensis ''Cavea'' is a low perennial herbaceous plant that is assigned to the family Asteraceae. ''Cavea tanguensis'' is currently the only species assigned to this genus. It has a basal rosette of entire, slightly leathery leaves, and stems of 5–25& ...'', a perennial herb that grows on scree near streams and glaciers in the Eastern Himalayas. These species have very little in common, other than having two types of flower heads and sharing a tendency towards dioecism. Both also have basal leaf rosettes, stretched leaves, with few spaced teeth on the margin, and both lack spines and latex. Taxonomy The subfamily Gymnarrhenoideae and tribe Gymnarrheneae were erected in 2009 by Jose Panero and Vicki Funk to ac ...
