Nuttallanthus Floridanus
''Nuttallanthus'' is a genus of four species of herbaceous annuals and perennials that was traditionally placed in the foxglove family Scrophulariaceae. Due to new genetic research, it has now been placed in the vastly expanded family Plantaginaceae. Three species of ''Nuttallanthus'' are native to North America and one to South America. ''Nuttallanthus'' was until the 1980s included in a wider circumscription of the genus '' Linaria'', a genus now considered restricted to the Old World. The members of this genus are known in English as toadflax, a name shared with several other related genera. The scientific name honors Thomas Nuttall. ;Species *''Nuttallanthus canadensis'' (Canada toadflax or oldfield toadflax) *'' Nuttallanthus floridanus'' (Apalachicola toadflax) *''Nuttallanthus texanus ''Nuttallanthus texanus'', the Texas toadflax, is an annual to biennial plant in the family Plantaginaceae found across much of the western United States.Sonoran Desert Wildflowers, ...

Nuttallanthus Canadensis
''Nuttallanthus canadensis'', the blue toadflax, Canada toadflax, or old-field toadflax, is a species of '' Nuttallanthus'' in the family Plantaginaceae, native to eastern North America from Ontario east to Nova Scotia and south to Texas and Florida.USDA Plants Profile''Nuttallanthus canadensis''/ref> Description It is an annual or biennial plant growing to 25–80 cm tall, with slender, erect flowering stems. The leaves are slender, 15–30 mm long and 1–2.5 mm broad. The flowers are purple to off-white, 10–15 mm long, appearing from mid spring to late summer.Huxley, A, ed. (1992). ''New RHS Dictionary of Gardening''. Distribution and habitat It is grown as an ornamental plant in its native area. It has been introduced to western North America and Europe, and is now locally naturalized, from Washington south to California, and also in Russia. It typically grows in bare areas and grassland.

Linaria
''Linaria'' is a genus of almost 200 species of flowering plants, one of several related groups commonly called toadflax. They are annuals and herbaceous perennials, and the largest genus in the Antirrhineae tribe of the plantain family Plantaginaceae. Taxonomy ''Linaria'' was traditionally placed in the family Scrophulariaceae. Phylogenetic analysis has now placed it in the vastly expanded family Plantaginaceae. Closely related genera include '' Nuttallanthus'' (American toadflaxes, recently split from ''Linaria''), ''Antirrhinum'' (snapdragons) and ''Cymbalaria'' (ivy-leaved toadflaxes). Cultivation Several ''Linaria'' species are cultivated as garden plants, and some are regarded as having a weedy habit. *Common toadflax or butter-and-eggs (''Linaria vulgaris''), a European species which is widely introduced elsewhere and grows as a common weed in some areas. *Broomleaf toadflax or Dalmatian toadflax ('' Linaria genistifolia'', syn.

Cymbalaria
''Cymbalaria'' is a genus of about 10 species of herbaceous perennial plants previously placed in the family Scrophulariaceae, but recently shown by genetic research to be in the much enlarged family Plantaginaceae. The genus is native to southern Europe. It is closely related to the genera ''Linaria'' and ''Antirrhinum'', differing in having creeping growth and flowers borne singly rather than in dense erect spikes. The common name toadflax is shared with ''Linaria'' and other related genera. The scientific name means "resembling a cymbal" for the somewhat rounded leaves. By far the best known species is ''Cymbalaria muralis'' (also called ivy-leaved toadflax, and Kenilworth ivy), native to southwest Europe. It has widely naturalised elsewhere and is commonly sold as a garden plant. ''C. muralis'' characteristically grows in sheltered crevices in walls and pathways, or in rocks and scree, making a trailing or scrambling plant up to 1 m long.

Antirrhinum
''Antirrhinum'' is a genus of plants commonly known as dragon flowers, snapdragons and dog flower because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are native to rocky areas of Europe, the United States, Canada, and North Africa. It is widely used as an ornamental plant in borders and as a cut flower. Description The Antirrhinum is morphologically diverse, particularly the New World group (''Saerorhinum''). The genus is characterized by personate flowers with an inferior gibbous corolla. Taxonomy ''Antirrhinum'' used to be treated within the family Scrophulariaceae, but studies of DNA sequences have led to its inclusion in a vastly enlarged family Plantaginaceae, within the tribe Antirrhineae. Circumscription The taxonomy of this genus is complex and not yet fully resolved at present. In particular the exact circumscription of the genus, especially the inclusion of the New World species (Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interspecific Hybrid
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an England, English botany, botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near Settle, North Yorkshire, Settle in the West Riding of Yorkshire and spent some years as an apprentice printer in England. Soon after going to the United States he met professor Benjamin Smith Barton in Philadelphia. Barton encouraged his strong interest in natural history. Early explorations in the United States In 1810 he travelled to the Great Lakes and in 1811 travelled on the Astor Expedition led by William Price Hunt on behalf of John Jacob Astor up the Missouri River. Nuttall was accompanied by the English botanist John Bradbury (naturalist), John Bradbury, who was collecting plants on behalf of Liverpool botanical gardens. Nuttall and Bradbury left the party at the trading post with the Arikara Indians in South Dakota, and continued farther upriver with Rams ...

Old World
The "Old World" is a term for Afro-Eurasia that originated in Europe , after Europeans became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia, which were previously thought of by their inhabitants as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and they have a p ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Plantaginaceae
Plantaginaceae, the plantain family, is a large, diverse family of flowering plants in the order Lamiales that includes common flowers such as snapdragon and foxglove. It is unrelated to the banana-like fruit also called "plantain." In older classifications, Plantaginaceae was the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales. Overview The plantain family as traditionally circumscribed consisted of only three genera: ''Bougueria'', ''Littorella'', and ''Plantago''. However phylogenetic research has indicated that Plantaginaceae ''sensu stricto'' (in the strict sense) were nested within Scrophulariaceae (but forming a group that did not include the type genus of that family, ''Scrophularia''). Although Veronicaceae (1782) is the oldest family name for this group, Plantaginaceae (1789) is a conserved name under the International Code of B ...

Scrophulariaceae
The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as shrubs. Flowers have bilateral (zygomorphic) or rarely radial (actinomorphic) symmetry. The Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. The family name is based on the name of the included genus ''Scrophularia'' L. Taxonomy In the past, it was treated as including about 275 genera and over 5,000 species, but its circumscription has been radically altered since numerous molecular phylogenies have shown the traditional broad circumscription to be grossly polyphyletic. Many genera have recently been transferred to other families within the Lamiales, notably Plantaginaceae and Orobanchaceae, but also several new families. - on linhere/ref> Several families of the Lamiales have had their circumscriptions enlarged to accommodate genera transferred from t ...
