Family Compositae

The largest family of flowering plants , the Compositae (Asteraceae), comprising about 1,100 genera and more than 20,000 species and characterized by many small flowers arranged in a head looking like a single flower and subtended by an involucre of bracts. A head may consist of both ray flowers and disk flowers, as in the sunflower, of disk flowers only, as in the burdock, or of ray flowers only, as in the dandelion.

Genus Artemisia

Annuals , biennials, perennials , subshrubs , or shrubs , 3-350 cm (usually, rarely not, aromatic ) . Stems 1-10+, usually erect , usually branched, glabrous or hairy (hairs basi- or medifixed ) . Leaves basal or basal and cauline; alternate; petiolate or sessile; blades filiform , linear , lanceolate, ovate , elliptic , oblong , oblanceolate , obovate , cuneate, flabellate , or spatulate , usually pinnately and/or palmately lobed , sometimes apically ± 3-lobed or -toothed, or entire, faces glabrous or hairy (hairs multicelled and filled with aromatic terpenoids and/or 1-celled and hollow, dolabriform , T-shaped) . Heads usually discoid , sometimes disciform (subradiate in A. bigelovii), in relatively broad, paniculiform arrays, or in relatively narrow, racemiform or spiciform arrays. Involucres campanulate , globose , ovoid , or turbinate , 1.5-8 mm diam. Phyllaries persistent , 2-20+ in 4-7 series, distinct , (usually green to whitish green, rarely stramineous ) ovate to lanceolate, unequal, margins and apices (usually green or white, rarely dark brown or black) ± scarious (abaxial faces glabrous or hairy) . Receptacles flat, convex , or conic (glabrous or hairy), epaleate (except paleate in A. palmeri) . Ray florets 0 (peripheral pistillate florets in disciform heads usually 1-20, their corollas filiform; corollas of 1-3 pistillate florets in heads of A. bigelovii sometimes ± 2-lobed, weakly raylike) . Disc florets 2-20(-30+), bisexual and fertile , or functionally staminate ; corollas (glabrous or ± hirtellous) usually pale yellow, rarely red, tubes ± cylindric , throats subglobose or funnelform , lobes 5, ± deltate. Cypselae (brown) fusiform , ribs 0 (and faces finely striate ) or 2-5, faces glabrous or hairy (not villous ), often gland-dotted (pericarps sometimes with myxogenic cells , without resin sacs ; embryo sac development monosporic) ; pappi usually 0 (coroniform in A. californica and A. papposa, sometimes on outer in A. rothrockii) . x = 9.

Species ca. 350-500, mostly Northern Hemisphere (North America, Eurasia ), some in South America and Africa.

As circumscribed here, there are five subgenera in Artemisia; four are represented in the flora area. Etymologies of the common names used for Artemisia species provide glimpses of their uses and demonstrate the rich diversity within the genus. The common name mugwort is from the Old English mucgwyrt, mucg meaning midge, and refers to the use of Old World herbaceous species in repelling flies and midges. Artemisia was called Motherwort in nineteenth century Maine (as an indication of the high esteem for this otherwise rather pedestrian plant), and in the herbal by R. Banckes (1525) : "This herb helpeth a woman to conceyve a chylde, and clenseth the mother, and maketh a woman to have her flowers." Early settlers in North America brought European plants of A. dracunculus, A. vulgaris, A. absinthium, and A. abrotanum into their herb gardens for seasoning and medicinal uses; they would also have learned about aboriginal uses of Artemisia species native to North America, uses that included fertility rites (sagebrush in western North America) and antihelminthics (wormwoods of grasslands and mountain habitats ) . Immigrants used A. annua (sweet Annie) in potpourris and later recognized its utility as an anti-malarial drug, a use that was well known in oriental medicine. Bulwand is the local name used for herbaceous wormwoods in Scotland, and green-ginger and Sailors tobacco are local names in England (T. Coffey 1993) . Use of the names sagewort and sagebrush in North America arise from the familiar aroma of culinary sage, Salvia officinalis (Lamiaceae) . Because true sages (Salvia) and sagewort/sagebrushes (Artemisia) are in separate families, the chemical similarities are an example of convergent evolution. The intense aroma and bitter taste of the plants from terpenoids and sesquiterpene lactones discourages herbivory and undoubtedly has contributed to the remarkable evolutionary success (measured by abundance as well as diversity) of species in this genus. Members of Artemisia are wind-pollinated and their heads and florets are exceptionally small (even for composites ) and, consequently, difficult to examine and assess. Nevertheless, the sexual constitution of floral heads is important in recognition of subgenera. Plant habits and ornamentations of receptacles have also figured in arriving at subgeneric circumscriptions; additional characteristics are enumerated in the descriptions . Artemisia has a well-deserved reputation for being taxonomically difficult. The number of subgenera varies from four to five in modern treatments, and the number of taxa recognized at the species or subspecific levels varies between 250 and 500 (K . Bremer and C. J. Humphries 1993; H. M. Hall and F. E. Clements 1923; Y. R. Ling 1982, 1995; P. P. Poljakov 1961; M. Torrell et al. 1999) . In this treatment, I recognize four native subgenera; subg. Seriphidium is endemic to Asia. In the flora area, the greatest diversity occurs in subg. Artemisia. Subgenus Absinthium can be segregated on the basis of hairs on the receptacle; it may be not phylogenetically distinct (L. E. Watson et al. 2002; J. Valles and E. D. McArthur 2001) . Subgenus Dracunculus is clearly distinguished by molecular differences, and subg. Tridentatae is well defined with the exception of A. pygmaea. This treatment is based on extensive fieldwork, review of recent research, and examination of thousands of specimens; taxonomic circumscriptions remain controversial. Molecular analyses have helped define subgenera but have not clarified relationships between closely related species. The morphologic characters useful in distinguishing species tend to be variable and are often hard to assess (i.e. , the sexuality of microscopic florets) . Users of the keys will meet with frustrations; descriptions of subgenera and illustrations will help in defining the major groupings of species. The subgenera are arranged in approximate phylogenetic order ; species are arranged alphabetically within the subgenera. Molecular studies define subg. Dracunculus as a major clade that is ancestral to the majority of Artemisia. The subgenera Absinthium, Tridentatae, and Artemisia can be classified as clades; they are weakly supported by molecular evidence.[1]
