Littorella uniflora Contents |
Littorella is a genus of two [1] to three [2] species of aquatic plants. Many plants live their entire lives submersed, and reproduce by stolons, but some are only underwater for part of the year, and flower when they are not underwater. [2]
Molecular data show Littorella to be sister to the rest of the genus Plantago . Thus, cladistics would allow it to be considered either as a separate genus or as part of Plantago. [2] [3] Some researchers, particularly Rahn in the 1990s, have considered Littorella to be located within Plantago, but this does not seem to be required given the molecular data and a closer look at morphology. [2]
Some authors have treated L. uniflora and L. americana to be one species, but molecular data show L. americana to be more closely related to L. australis than it is to L. uniflora, which argues for recognizing three species. Other considerations, such as the wider range and more frequent flowering of L. uniflora, also argue for separate species. It seems likely that the genus originated in Europe and first spread to North America, and from there to South America, with both events happening in the Pleistocene or later. [2]
The European species is found in a wide range of habitats, from arctic to Mediterranean. The North and South American species are found in a more limited range of temperate climates. [2]
Plantago is a genus of about 200 species of flowering plants in the family Plantaginaceae, commonly called plantains or fleaworts. The common name plantain is shared with the unrelated cooking plantain. Most are herbaceous plants, though a few are subshrubs growing to 60 centimetres tall.
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.
Antirrhinum is a genus of plants commonly known as dragon flowers or snapdragons because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are also sometimes called toadflax or dog flower. They are native to rocky areas of Europe, the United States, Canada, and North Africa. Antirrhinum species are widely used as ornamental plants in borders and as cut flowers.
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.
Phrymaceae, also known as the lopseed family, is a small family of flowering plants in the order Lamiales. It has a nearly cosmopolitan distribution, but is concentrated in two centers of diversity, one in Australia, the other in western North America. Members of this family occur in diverse habitats, including deserts, river banks and mountains.
Lactoris fernandeziana is a flowering shrub endemic to the cloud forest of Masatierra — Robinson Crusoe Island, of the Juan Fernández Islands archipelago of Chile. It is the only extant species in the genus Lactoris.
Ilex mucronata, the mountain holly or catberry, is a species of holly native to eastern North America, from Newfoundland west to Minnesota, and south to Maryland and West Virginia.
Aldrovanda is a genus of carnivorous plants encompassing one extant species and numerous extinct taxa. The genus is named in honor of the Italian naturalist Ulisse Aldrovandi, the founder of the Botanical Garden of Bologna, Orto Botanico dell'Università di Bologna. Aldrovanda vesiculosa has been reported from scattered locations in Europe, Asia, Africa, and Australia.
Brunfelsia is a genus of flowering plants belonging to subfamily Petunioideae of the nightshade family Solanaceae. The 50 or so species have been grouped into the three sections: Brunfelsia, Franciscea and Guianenses, which differ significantly in both distribution and characteristics, although molecular data have revealed that only two sections are natural (monophyletic), namely the Caribbean section Brunfelsia and a common section for all South American species. Linnaeus named the genus for the early German herbalist Otto Brunfels (1488–1534).
Plantago nubicola is a plant found in Peru, Bolivia, and Argentina.
Planchonella australis, also known by the synonym Pouteria australis, is a medium to tall rainforest tree of the family Sapotaceae native to Queensland and New South Wales, Australia. It is known by the common name black apple, wild plum, yellow buttonwood, black plum and yellow bulletwood.
Aragoa is a genus of woody perennials native to the páramo of Colombia and north-western Venezuela. It classified as the sister taxon to Littorella and Plantago, all of which are now classified in the family Plantaginaceae. It is found at elevations above about 3000 m.
Drosera uniflora is a species in the carnivorous plant genus Drosera that is native to southern Chile, Argentina, and the Falkland Islands. It is a tiny sundew with a solitary white flower as its name would suggest. Stalked glands on its leaves, which secrete sticky mucilage at the tips, are used to capture and hold insect prey, from which the plant derives the nutrients it cannot obtain in sufficient quantity from the soil. It was formally described in 1809 by botanist Carl Ludwig Willdenow.
Plantago hedleyi is a species of flowering plant in the plant family Plantaginaceae that is endemic to Lord Howe Island, Australia. Joseph Maiden described P. hedleyi in 1914. Plants of this plantain are large with large leaves, up to nine veins, wide petioles, and long spikes with dozens of flowers and fruits with up to 5 seeds.
The Antirrhineae are one of the 12 tribes of the family Plantaginaceae. It contains the toadflax relatives, such as snapdragons.
Plantago triantha is a species of flowering plant in the family Plantaginaceae that is native to Tasmania, Australia and the subantarctic Auckland Islands of New Zealand. Robert Brown described the species in 1810. Plants of this species of plantain are annual or perennial with a rosette habit, fleshy toothed leaves, and short inflorescences.
Sibthorpia is a genus of flowering plants in the family Plantaginaceae, with a peculiar distribution in the mountains of North America, South America and Africa, and the coasts of Europe.
Schoenus australis is a species of sedge endemic to locations near the southern coast of South Africa.
Plantago stauntonii is a species of flowering plant in the family Plantaginaceae that is endemic to Île Amsterdam and Île Saint-Paul in the French southern territories. Sir Heinrich Wilhelm Reichardt described P. stauntonii in 1871, naming it after Sir George Leonard Staunton, who collected specimens of it in 1793.
Plantago unibracteata is a species of flowering plant in the family Plantaginaceae that is endemic to New Zealand. Knud Rahn gave the species its current name in 1996, based on Joseph Dalton Hooker's original description in 1854. Plants of this species of plantain are perennial with a rosette habit, with narrowly angular-ovate leaves with few teeth, and numerous angular or rounded seeds.
