Pogogyne Tenuiflora
''Pogogyne tenuiflora'' is an extinct species of annual plant in the mint family. Endemic to Guadalupe Island in the eastern Pacific, the Guadalupe mesa mint was only known from a single specimen collected by Edward Palmer in 1875. The species was described from Palmer's specimens by Asa Gray in 1876. ''Pogogyne tenuiflora'' is a small, aromatic annual herb, with inflorescences consisting of flowers in bracteate verticils forming dense terminal spikes. The corollas are blue-purple and tubular, with an erect, entire upper lip and a spreading 3-lobed lower lip. The corollas measure long. The lower pair of stamens measure long. The style is bearded for about below the branches. The two sterile upper anthers place this species within the ''Hedeomoides'' subgenus of ''Pogogyne'', which was recognized as its own genus by John Isaac Briquet in 1896.Engler, Heinrich Gustav Adolf; Prantl, Karl Anton Eugen (1896) ''Naturlichen Pflanzenfamilien'' 4, Abt. 3a: 295 During his visit, Palm ...

Subgenus
In biology, a subgenus ( subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all tho ... (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Flora Of North America
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Endemic Flora Of Guadalupe Island
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Pogogyne
''Pogogyne'' is a small genus of flowering plants in the Lamiaceae, mint family known generally as mesamints or mesa mints. They are native to Oregon, Idaho, California, and Baja California. These are small annual plants with glandular, aromatic foliage. They are somewhat variable in appearance but are mostly minty-scented herbs with leaves and flower inflorescences bordered with stiff hairs. The flowers are white or a shade of purple or pinkish-lavender. The best known species is the critically endangered vernal pool species Pogogyne abramsii, San Diego mesa mint, ''P. abramsii'', which is now found only in a few isolated patches of ground near San Diego, California. ;Species # ''Pogogyne abramsii'' Howell - San Diego mesa mint - San Diego County # ''Pogogyne clareana'' J.T.Howell - Santa Lucia mesa mint - Monterey County # ''Pogogyne douglasii'' Benth. - Douglas' mesa mint - Central + Northern California (Coast Ranges + Central Valley) # ''Pogogyne floribunda'' Jokerst - profu ...

Guadalupe Caracara
The Guadalupe caracara (''Caracara lutosa'') or mourning caracara is an extinct bird of prey belonging to the falcon family (Falconidae). It was, together with the closely related crested caracara (''Caracara plancus''), formerly placed in the genus '' Polyborus''. It was also known as the quelili or the calalie. Description The Guadalupe caracara was similar to the crested caracara, but differed in having less white on the upper breast and being barred on the belly rather than black. Distribution and taxonomy This species inhabited Mexico's Guadalupe Island until the beginning of the 20th century. The crested caracara is sometimes incorrectly referred to as "Guadalupe caracara", because the extinct birds were formerly considered a subspecies of the extant taxon. They were reinstated as a full species in 2000. History Described as "evil" and "vicious" by early observers, it was driven to extinction by a hunting and poisoning campaign led by goat herders on Guadalupe Island. A ...

Castilleja Guadalupensis
''Castilleja guadalupensis'' is an extinct species of plant in the broomrape family Orobanchaceae commonly known as the Guadalupe paintbrush. The plant was only found on the central and northern portions of Guadalupe Island, an eastern Pacific island of Mexico. It was one of two endemic species of ''Castilleja'' to the island, the other, '' Castilleja fruticosa'', mainly surviving on offshore islets. ''C. guadalupensis'' was first found by Edward Palmer on the middle of Guadalupe in 1875, although the plants were initially recognized as '' Castilleja foliolosa''. The type specimen was later collected by ornithologist Alfred Webster Anthony on a March 1897 expedition to Guadalupe with Townshend Stith Brandegee. A year later in 1898, sailor and hunter Harry Drent collected some specimens of ''C. guadalupensis''. The species has not been found since and is presumably extinct due to the overgrazing of the island by introduced feral goats. Brandegee described the species in 1903. '' ...

Reid Venable Moran
Reid Venable Moran (June 30, 1916 – January 21, 2010) was an American botanist and the curator of botany at the San Diego Natural History Museum from 1957 to 1982. Moran was the world authority on the Crassulaceae, a family of succulent plants, and in particular the genus '' Dudleya'', the subject of his Ph.D. dissertation. He named at least 18 plants new to science — some in that family and some not — and published many papers elucidating relationships within the Crassulaceae. As a mark of the respect he earned among his peers, more than a dozen plants have been named for him. Jane Goodall described Moran as "a sort of living myth in botanical exploration in Baja California and the Pacific Islands of Mexico," citing specifically his analysis of the environmental impact of introduced species (especially goats) on the flora of Guadalupe Island. Biography Early life Born in Los Angeles, California on June 30, 1916, to Edna Louise Venable and Robert Breck Moran (a petroleum ...

Flora (publication)
A Flora is a book or other work which describes the plant species occurring in an area or time period, often with the aim of allowing identification. The term is usually capitalized to distinguish it from the use of "flora" to mean the plants rather than their descriptions. Some classic and modern Floras are listed below. Traditionally Floras are books, but some are now published on CD-ROM or websites. The area that a Flora covers can be either geographically or politically defined. Floras usually require some specialist botanical knowledge to use with any effectiveness. A Flora often contains diagnostic keys. Often these are ''dichotomous'' keys, which require the user to repeatedly examine a plant, and decide which one of two alternatives given in the Flora best applies to the plant. Floras produced at a local or regional level rarely contain identification keys. Instead they aim to impart more detailed understanding of the local status and distribution of that area's plants. ...

Ira Loren Wiggins
Ira Loren Wiggins (1 January 1899 – 28 November 1987) was an American botanist, Curator of the Dudley Herbarium, and Director of the Natural History Museum (1940–1962) at Stanford University. He was a Stanford faculty member from 1929 until his retirement in 1964. He was the first recipient of the Fellow's Medal of the California Academy of Sciences. His ''Flora of Baja California'' is a standard work on the botany of the Baja peninsula and on the many islands of the Gulf of California. Wiggins attended Occidental College as an undergraduate and received his M.A. at Stanford, studying with LeRoy Abrams, and where he won a university fellowship in botany in 1927. He earned his PhD in 1930 with a thesis on the flora of San Diego County. Wiggins made several botanical collecting trips to the Sonoran Desert, collaborating with Forrest Shreve in a description of the vegetation and flora of the North American Sonoran Desert including portions of Arizona, New Mexico, California, So ...

Hesperelaea
''Hesperelaea'' is a plant genus with only one species, probably now extinct. ''Hesperelaea palmeri'' was found only on Guadalupe Island, a small island in the Pacific Ocean, part of the Mexican state of Baja California, about southwest of Ensenada. The last collection of the plant on the island was in 1875, so the species and the genus must now be presumed extinct. An intensive search for the plant in 2000 was unsuccessful. At the time of the collection of the type material in 1875, ''Hesperelaea palmeri'' was found only in a single canyon on the east side of the island. It was a shrub with broadly lanceolate leaves up to 5 cm long. Flowers were pale yellow, the petals over 10 mm long. The species was unusual in the family in having fully distinct petals. Phylogenetic analyses based on DNA from the nuclear genome as well as mitochondrial and chloroplast DNA suggest that ''H. palmeri'' is closely related to the genera '' Forestiera'' and '' Priogymnanthus'' in tribe O ...
