There are 42 accepted species of flowering plants in the genus Dahlia, according to The Plant List. [1] The sectional classification of Dahlia sensu Sørensen (1969) [ 2 ] as updated by Saar et al. (2003) [ 3 ] and Hansen (2004) [ 4 ] and (2008) [ 5 ] is as follows (excluding infraspecific taxa);
The other major grouping is the core Dahlia clade (CDC), which includes most of the section Dahlia. The remainder of the species occupy what has been described as the variable root clade (VRC) which includes the small section Pseudodendron but also the monotypic section Epiphytum and a number of species from within section Dahlia.
'Moonfire' (VanDusen Botanical Garden, Stan Shebs)The following is a list of dahlia cultivars which have gained the Royal Horticultural Society's Award of Garden Merit.They are tuberous perennials, originally from South America, with showy daisy-like composite flowerheads in all shades and combinations of white, yellow, orange, pink and red, flowering in late summer and autumn (fall).
The horticultural cultivation of the dahlia plant has resulted in over 57,000 registered cultivars of dahlia. [1] Several of them are listed below. In North America the American Dahlia Society [2] is responsible for the process of accepting a named variety as a cultivar. They also publish the list of currently found Dahlia Cultivars in North ...
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary relationships.
Dahlia pinnata is a perennial herbaceous plant with a rhizome and tuberous roots, reaching a height of 70 to 120 centimetres (28 to 47 inches), rarely 160 cm.The stem is erect, and branched only in the inflorescence.
The requirement for a rank is a major difference between traditional and phylogenetic nomenclature. It has several consequences: it limits the number of nested levels at which names can be applied; it causes the endings of names to change if a group has its rank changed, even if it has precisely the same members (i.e. the same circumscription ...
The hierarchy of biological classification's eight major taxonomic ranks. Intermediate minor rankings are not shown. In botanical nomenclature, variety (abbreviated var.; in Latin: varietas) is a taxonomic rank below that of species and subspecies, but above that of form. [1] As such, it gets a three-part infraspecific name. It is sometimes ...
