Hymenoxys Texana
''Hymenoxys texana'' is a rare species of flowering plant in the Asteraceae, aster family known by the common names prairie dawn, Texas prairie dawn-flower, and Texas bitterweed. It is Endemism, endemic to Texas, where it is known only from the general vicinity of Houston, Texas, Houston. It is threatened by the loss of its habitat. It is a federally listed endangered species of the United States. ''Hymenoxys texana'' is an annual herb with delicate reddish or purplish stems growing only 10 or 15 centimeters (4-6 inches) tall. The leaves have rubbery, glandular blades which may be simple or divided into lobes, particularly at mid-stem. The inflorescence is a solitary Head (botany), flower head or an open cluster of several heads. Each head is under a centimeter wide and has 6 to 8 yellow ray florets each 2 or 3 millimeters long.

Joseph Nelson Rose
Joseph Nelson Rose (January 11, 1862 – May 4, 1928) was an American botanist. He was born in Union County, Indiana. His father died serving during the Civil War when Joseph Rose was a young boy. He later graduated from high school in Liberty, Indiana. He received his Ph.D. in Biology from Wabash College in 1889. having received his B.A. in Biology and M.A. Paleobotany earlier at the same institute. He married Lou Beatrice Sims in 1888 and produced with her three sons and three daughters. Rose worked for the U.S. Department of Agriculture and became an assistant curator at the Smithsonian in 1896. While Rose was employed by the national museum, he was an authority on several plants families, including Apiaceae (Parsley Family) and Cactaceae (Cactus Family). He made several field trips to Mexico, and presented specimens to the Smithsonian and the New York Botanical Garden. With Nathaniel Lord Britton, Rose published many articles on the Crassulaceae.

Nostoc
''Nostoc'', also known as star jelly, troll’s butter, spit of moon, fallen star, witch's butter (not to be confused with the fungi commonly known as witches' butter), and witch’s jelly, is the most common genus of cyanobacteria found in various environments that may form colonies composed of filaments of moniliform cells in a gelatinous sheath of polysaccharides. ''Nostoc'' is a genus of photosynthetic, Gram-negative cyanobacteria that can be found in both terrestrial and aquatic environments. It may also grow symbiotically within the tissues of plants, providing nitrogen to its host through the action of terminally differentiated cells known as heterocysts. ''Nostoc'' is a genus that includes many species that are diverse in morphology, habitat distribution, and ecological function. ''Nostoc'' can be found in soil, on moist rocks, at the bottom of lakes and springs, and rarely in marine habitats. It may also be found in terrestrial temperate, desert, tropical, or polar env ...

Plants Described In 1891
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abilit ...

Endemic Flora Of Texas
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus, Cytisus aeolicus'' is an endemite of the Italian flora. ''Enidae, Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a Invasive species, non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a specie ...

Hymenoxys
''Hymenoxys'' (rubberweed or bitterweed) is a genus of plants in the sunflower family, native to North and South America. It was named by Alexandre Henri Gabriel de Cassini in 1828. Plants of this genus are toxic to sheep due to the presence of the sesquiterpene lactone hymenoxon. ; Species * '' Hymenoxys ambigens'' - Pinaleno Mountain rubberweed - Arizona New Mexico * '' Hymenoxys anthemoides'' - Rio Grande do Sul, Rio de Janeiro, Paraguay, Uruguay, Argentina * '' Hymenoxys biennis'' - Utah * '' Hymenoxys bigelovii'' - Utah Arizona New Mexico * '' Hymenoxys brachyactis'' - East View rubberweed - New Mexico * '' Hymenoxys brandegeei'' - Arizona New Mexico Colorado * '' Hymenoxys cabrerae'' - Argentina * '' Hymenoxys californica'' - California, Baja California * '' Hymenoxys chrysanthemoides'' - San Luis Potosí, Veracruz, Zacatecas, México State, Puebla, Oaxaca, Hidalgo * '' Hymenoxys cooperi'' - Cooper's rubberweed - California Nevada Arizona Utah Idaho Oregon N ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
