Sneed's Pincushion Cactus
''Pelecyphora sneedii'' (Synonym (taxonomy), syn. ''Coryphantha sneedii'') is a rare species of cactus known by the common names Sneed's pincushion cactus and carpet foxtail cactus. It is endemic to the Chihuahuan Desert of the southwestern United States and northwestern Mexico. It is a small, variable cactus with a lengthy taxonomic history, and is often subdivided into a number of subspecies or varieties. It is usually found on steep, rocky habitats, primarily of limestone geology, in desert scrub or coniferous forest. A species of conservation concern, ''P. sneedii'' faces threats from poaching, Urban sprawl, urban encroachment, and Wildfire, wildfires. The former cacti species ''Coryphantha orcuttii'' has been lumped into ''sneedii'' as a subspecies. ''P. sneedii'' also Intergradation, intergrades with ''Pelecyphora vivipara'', further complicating classification. Because of the variation and intergradation of ''P. sneedii'', it forms a species complex. Description Morph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nathaniel Lord Britton
Nathaniel Lord Britton (January 15, 1859 – June 25, 1934) was an American botanist and taxonomist who co-founded the New York Botanical Garden in the Bronx, New York. Early life Britton was born in New Dorp in Staten Island, New York to Jasper Alexander Hamilton Britton and Harriet Lord Turner. His parents wanted him to study religion, but he was attracted to nature study at an early age. He was a graduate of the Columbia University School of Mines and afterwards taught geology and botany at Columbia University. He joined the Torrey Botanical Club soon after graduation and was a member his entire life. He married Elizabeth Gertrude Knight, a bryologist, on August 27, 1885. They had met when she joined the club and were lifelong collaborators in botanical research. New York Botanical Garden During their honeymoon in 1888, they visited Kew Gardens, which led to his wife proposing a botanical garden for New York at a Torrey Club meeting. Together, they campaigned to bring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains '' microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Engelmann
George Engelmann, also known as Georg Engelmann, (2 February 1809 – 4 February 1884) was a German-American botanist. He was instrumental in describing the flora of the west of North America, then very poorly known to Europeans; he was particularly active in the Rocky Mountains and northern Mexico, one of his constant companions being another German-American, the botanical illustrator Paulus Roetter. Biography Origins George Engelmann was born in Frankfurt am Main, Germany, the oldest of thirteen children, nine of whom reached maturity. His father, Julius Bernhardt Engelmann, was a member of a family from which for several successive generations were chosen ministers for the Reformed Church at Bacharach-on-the-Rhine. Julius was a graduate of the University of Halle, and was also educated for the ministry, but he devoted his life to education. He established a school for young women in Frankfurt, which was rare at the time. George Engelmann's mother, Julie Antoinette, was the ...

Coryphantha
''Coryphantha'' (from Greek, "flowering on the top"), or beehive cactus, is a genus of small to middle-sized, globose or columnar cacti. The genus is native to arid parts of Central America, Mexico, through Arizona, New Mexico, and western Texas and north into southwestern, central, and southeastern Montana. With its two subgenera, 57 species and 20 subspecies, it is one of the largest genera of cactus.Dicht, Reto F. and Lüthy, Adrian D. (2005) ''Coryphantha: Cacti of Mexico and Southern USA''. Springer, Berlin, p. 1, Description There are four characteristics that distinguish ''Coryphantha'' from other cacti. # Their bodies do not have ribs, just tubercles.Dicht, Reto F. and Lüthy, Adrian D.

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance ( shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fr ...

Cochemiea Macdougallii
''Cochemiea macdougallii'' is a species of cactus in the genus ''Cochemiea''. The plant has a greenish-gray epidermis and black spines. It is only known from Oaxaca, Mexico. Taxonomy The species was first described in 1961 by Edward Johnston Alexander Edward Johnston Alexander (July 31, 1901 – August 18, 1985) was an American botanist who discovered three species and one genus. He is the author or one of the authors of 205 entries in the International Plant Names Index. He was born in Ashevil ... as ''Ortegocactus macdougallii''. It was the only species in Alexander's genus ''Ortegocactus''. ''Ortegocactus'' was later synonymized with ''Cochemiea'', but a name in that genus was only provided in 2021.

Neolloydia
''Neolloydia'' is a formerly recognized genus of cacti. The genus was first erected by Britton and Rose in 1922. Edward F. Anderson regarded ''Neolloydia'' as being poorly defined, with the result that species that had at times been included in ''Neolloydia'' were afterwards placed in multiple genera, including ''Coryphantha'', ''Echinomastus'', '' Escobaria'', '' Mammillaria'', ''Sclerocactus'', ''Thelocactus'' and '' Turbinicarpus''. In his 2001 book, Anderson firmly placed only one species in the genus, ''Neolloydia conoidea'', with another, ''Neolloydia matehualensis'', being regarded as only a variant of ''N. conoidea''. , Plants of the World Online treated ''Neolloydia conoidea'' as a synonym of ''Cochemiea conoidea'', and ''Neolloydia'' as a synonym of ''Cochemiea''. Species that have been placed in ''Neolloydia'' include: *''Neolloydia clavata'' → ''Coryphantha clavata'' *''Neolloydia conoidea'' → ''Cochemiea conoidea'' *''Neolloydia horripila'' → ''Kadenicarpu ...

Cochemiea
''Cochemiea'' is a genus of cactus. It has previously been synonymized with ''Mammillaria'', but molecular phylogenetic studies have shown that when broadly circumscribed, ''Mammillaria'' is not monophyletic, and ''Cochemiea'' has been accepted as a separate genus. Taxonomy A 2021 molecular phylogenetic study of the "mammilloid clade", which included the genera ''Cochemiea'', ''Coryphantha'', ''Cumarinia'', ''Escobaria'', ''Mammillaria'', ''Neolloydia'' and ''Ortegocactus'', showed that it consisted of four monophyletic groups, which the authors re-circumscribed into four genera: '' Cumarinia''; ''Mammillaria'', with a reduced number of species; ''Coryphantha'', expanded to include species previously placed in ''Mammillaria'' and ''Escobaria''; and ''Cochemiea'', expanded to include a large number of species previously placed in ''Mammillaria'', as well as ''Neolloydia conoidea''. Species In 2021, Breslin, Wojciechowski and Majure placed the following species in the genus, some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Franklin Mountains (Texas)
The Franklin Mountains of Texas ( es, Sierras de los Mansos) are a small range long, wide that extend from El Paso, Texas north into New Mexico. The Franklins were formed due to crustal extension related to the Cenozoic Rio Grande rift. Although the present topography of the range and adjoining basins is controlled by extension during rifting in the last 10 million years, faults within the range also record deformation during the Laramide orogeny, between 85 and 45 million years ago. The highest peak is North Franklin Peak at . Much of the range is part of the Franklin Mountains State Park. The mountains are composed primarily of sedimentary rock with some igneous intrusions. Geologists refer to them as tilted-block fault mountains and in them can be found 1.25 billion-year-old Precambrian The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon.
