Description

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.

Tribe Lactuceae

The Lactuceae are a tribe of closely related genera of the sunflower family that are easily recognized because the flowering heads are composed of wholly of ligulate florets that are usually 5-lobed. Another very distinguishing feature is the milky sap . Although not apparent without magnification, the pollen is distinctive in that the spines are more or less restricted to discrete ridges or flanges on the surface of the grain. In other members of the family the spines are distributed more or less evenly over the surface of the pollen grain . The pappus usually consists of scales or stiff hairs . -- Gerald D. Carr.

Genus Taraxacum

Perennials , (10-) 30-400(-600+ in fruit) cm (sexual or apomictic) ; taprooted or with branched caudices. Stems (1-10+) erect or ascending , scapiform (terete ), simple (hollow), glabrous or villous proximal to heads . Leaves basal (in rosettes, erect or patent to nearly horizontal) ; petiolate or sessile; blades oblong to obovate or oblanceolate to linear-oblanceolate, runcinate or lyrate (bases cuneate to ± attenuate), margins subentire to dentate or pinnately lobed (apices rounded or obtuse to acute or acuminate, faces glabrous or glabrate to sparsely villous, pilose , or villosulous ) . Heads borne singly. Calyculi persistent , of (6-) 8-18(-20) broadly ovate to lanceolate bractlets in (1-) 2-3 series, distinct (appressed before flowering, recurved to spreading or reflexed in fruit), unequal (shorter than phyllaries, margins scarious , ciliate or not, apices corniculate, callous , or neither) . Involucres campanulate to cylindro-campanulate or urceolate to cylindric , 8-40 mm diam. Phyllaries 7-25 in 2(-3) series, weakly coherent proximally in buds (interlocking folded margins), distinct later, erect (sometimes slightly spreading) in flower, closing at fruit maturation, reflexed at dispersal (exposing globes of cypselae with fully spread pappi), ± equal, herbaceous, glabrous; inner lanceolate to linear-lanceolate, margins scarious, ciliate or not, apices acuminate, sometimes corniculate , callous, or flat. Receptacles ± flat, epaleate. Florets (15-) 20-150; corollas yellow, sometimes greenish, rarely cream or pale pink [white], often purplish- or gray-striped abaxially (anthers yellow or yellow-cream, sometimes darker; styles yellow or greenish, sometimes grayish to blackish) . Cypselae straw-colored to olive, brown, or red to pale or dark gray, bodies oblanceoloid to obovoid , ± flattened (distally ± swollen, forming discrete, conic, or terete "cones" supporting beaks [without cones]), beaked [beakless], ribs 4-12(-15), faces muricate (at least distally) [nearly smooth ], glabrous; pappi persistent, of 50-105+ distinct, white to cream-colored or yellowish to sordid , equal, barbellulate bristles in 1 series. x = 8.

Species 60(-2000) : North America, South America, Eurasia ; worldwide weeds (e.g. , Taraxacum officinale, T. erythrospermum) .

The type of the genus, Taraxacum officinale, is conserved. This name is linked to the (very general) description of Leontodon taraxacum Linnaeus. A. J. Richards (1985) typified T. officinale, via L. taraxacum, on a specimen that is apparently referable to T. campylodes Haglund, a microspecies of sect. Crocea restricted to Lapland, which thus became the basis of sect. Taraxacum. J. Kirschner and J. Åtepánek (1987) underlined that this typification of T. officinale does not reflect usage of the name, which raises considerable ambiguity as to its application , because Richards essentially defined a new content for it. The species usually referred to as T. officinale must now be referred to sect. Ruderalia (Kirschner and Åtepánek) ; no name was proposed that would correspond closely with the species currently called T. officinale. A proposal to conserve the name T. officinale with a neotype that would preserve its common usage for this widespread entity has been suggested; this has yet to be discussed fully.

Taraxacum Zinn (1757) (= Leontodon Linnaeus) is a rejected name .

The genus has been monographed by H. Handel-Mazzetti (1907) and by R. Doll (1974) . Infrageneric nomenclature has recently been reviewed by A. J. Richards (1985) and by J. Kirschner and J. tepánek (1987, 1997) . The European species were treated by Richards and P. D. Sell (1973) and much work has been done since; there is no overall treatment for Asia; Russian authors have covered Siberia. The number of species in the genus depends on the disposition of agamic microspecies within species complexes, which varies greatly among authors, particularly in Europe [e.g., A. A. Dudman and Richards (1997) recognized 105 species for Great Britain and Ireland]. North American

Taraxacum, particularly in the boreal and arctic zones, has been investigated by numerous researchers, many of whom incorporated new taxa described by H. Dahlstedt (1906) ; only works touching North America north of Mexico are mentioned here. Obviously, Scandinavian and Russian works also were significant (e.g., Dahlstedt; Doll 1977; M. L. Fernald 1933; E. L. Greene 1901b; G. Haglund 1943, 1946, 1948, 1949; M. P. Porsild 1930; P. A. Rydberg 1901), but often in a manner limited geographically or taxonomically, and no complete review exists. Most often, the taxonomy of the genus has been presented within the context of floras (e.g., S. G. Aiken et al. , http://www.mun.ca/biology/delta/arcticf/_ca/www/asta.htm, with excellent photographs of Arctic species; T. W. Böcher et al. 1978; A. Cronquist 1955, 1994; Fernald 1950; H. A. Gleason and A. Cronquist 1991; E. Hultén 1955, 1968; A. E. Porsild 1950b, 1957, 1964; A. E. Porsild and W. J. Cody 1980; H. J. Scoggan 19781979, part 4; Rydberg 1900c) . The result of all these efforts has not been a clarification of the North American situation, but rather a taxonomy and nomenclature in utter confusion (Cronquist 1994) . The current treatment does not solve all nomenclatural and taxonomic problems, many of which will depend for their ultimate solution on work done in Europe.

I have adopted a broad definition of Taraxacum species for North America, broader at least than what is usually seen in European treatments. For instance, the species most familiar to North Americans were introduced from Europe (T. officinale and T. erythrospermum; see below for a justification of the use of these names), possibly several times, and represent variable agamic complexes, but this variation appears continuous and multidimensional. There seems to be no utility for the users in describing a multitude of narrowly defined microspecies. For the native arctic and western alpine species, the impact of the Pleistocene glaciations, which covered much of the territory now occupied by those species except for ice-free parts of Alaska and Yukon, must be considered. It is likely that most populations spread recently from southern or Beringian refugia after the ice withdrew and that the number of species that migrated is restricted. Isolation in the Rocky Mountains and adjacent areas may explain some of the phenotypic diversity , but not enough to warrant a large number of narrowly defined, endemic entities. The situation in eastern North America (Greenland, Labrador, Newfoundland, and adjacent areas) may have been influenced by the amphi-Atlantic dispersal of some taxa. Again, given the small number of such species in the North American flora, all concentrated in that region, it is unlikely that the number of species actually present would reach the number that has been described for the area. Therefore, at the present time, delimitation of readily distinguishable taxa appears more useful than trying to dissect finely the variation present into microspecies that would have little experimental validation.

Another reason for using broad species limits is provided by population genetics. For instance, in Europe, S. B . J. Menken et al. (1995) showed that diploid and triploid members of Taraxacum sect. Ruderalia are less genetically isolated than formerly supposed and form a cohesive unit , because of the exchange of genetic material between ploidy levels despite the fact that the latter are usually agamic. The molecular study of genetic variation by L. M. King (1993) in introduced asexual Taraxacum taxa in North America also shows the importance of hybridization to explain variation, in addition to mutations , another important factor (King and B. A. Schaal 1990) . M. T. Brock (2004) also documented gene exchange between the introduced agamic T. officinale and native diploid populations of T. ceratophorum in Colorado. This is cause for conservation concern in areas where introduced dandelions, notably the common dandelion, invade populations of native species , such as in the Gulf of Saint Lawrence area or the western Cordilleras . It is also possible that the prolific common dandelions not only genetically assimilate but also competitively displace native populations, which might be the case for some populations of T. laurentianum in western Newfoundland.

A. A. Dudman and A. J. Richards (1997) described some of the sources of phenotypic plasticity (or drying artifacts ) in Taraxacum that may affect the identification (or delimitation) of species: juvenile and shaded leaves usually are less divided than older, sun-exposed or stressed ones, and the terminal lobes usually are smaller; some traits described as characteristic of a species may occur on only some leaves of a rosette; ligule color may change in dried material ; cypsela size, though mostly consistent within species, may vary considerably within a head, the outer often being shorter; finally, cypsela color changes with maturity and insolation, and fades on specimens, and in some groups, the variation in color is such that this trait may lose its significance in delimiting entities. R. J. Taylor (1987) also emphasized the importance of phenotypic plasticity in weedy dandelion morphologic variation.

There is a spontaneous mutant form of Taraxacum erythrospermum (called T. laevigatum forma scapifolium F. C. Gates & S. F. Prince. in which one or more lobed and dentate leaves (or bracts), progressively reduced distally, are present on the scape or peduncle. Also, calyculus bracts are more or less modified to enlarged, lobed and dentate bracts, instead of the usual bractlets. The phyllaries appear unaffected. The form is genetically determined, as it bred true. This shows that scapes of dandelions are modified stems where leaf expression is repressed, and that calyculi are indeed distinct in origin from the involucres and should be considered as a separate structure and not as an external series of the involucre, as is often done in descriptions.

Evolution and population biology in Taraxacum, notably with respect to breeding systems, apomixis, and variation, has been the object of numerous studies (e.g., J. C. M. den Nijs and S. B. J. Menken 1994; J. Hughes and A. J. Richards 1988, 1989; L. M. King 1993; King and B. A. Schaal 1990; J. C. Lyman and N. C. Ellstrand 1998; M. Mogie and H. Ford 1988; Mogie and Richards 1983; Richards 1970, 1970b, 1973, 1989, 1996; O. T. Solbrig 1971; R. J. Taylor 1987) . Molecular phylogenetic studies have not been effective so far in solving problems of relationships within Taraxacum (e.g., J. Kirschner et al. 2003) .

Chromosome counts of North American Taraxacum species are few and mainly come from A. W. Johnson and J. G. Packer (1968), T. Mosquin and D. E. Hayley (1966), G. A. Mulligan (1984), and Packer and G. D. McPherson (1974) . I have not been able to examine all vouchers , and it has been difficult sometimes to attribute reports to species. The same problem exists with Russian chromosome number reports and I prefer not to include them here (see the website of S. G. Aiken et al. for such references) .

Taraxacum species have been used medicinally (mostly as a diuretic) and in alimentation (as greens and to make wine) ; they are particularly rich sources of vitamin C (E. Small and P. M. Catling 1999) .[1]
