Hesperoyucca Whipplei
''Hesperoyucca whipplei'' ( syn. ''Yucca whipplei''), the chaparral yucca, our Lord's candle, Spanish bayonet, Quixote yucca or foothill yucca, is a species of flowering plant closely related to, and formerly usually included in, the genus ''Yucca''. It is native to southwest communities of North America. Description It produces a stemless cluster of long, rigid leaves which end in a sharp point. The leaves are , rarely to , long and wide, and gray-green in color. The leaf edges are finely saw-toothed. The single inflorescence grows extremely fast, and reaches tall, bearing hundreds of elliptical (bell-shaped) white to purplish flowers in diameter on a densely branched panicle up to broad, covering the upper half of the inflorescence. The fruit is a dry winged capsule, which splits open at maturity to release the seeds. According to Guinness the pedicel of the H. whipplei inflorescence can grow up to ten inches (25 cm) a day towards an eventual height of 11ft 11in (3.65 ...

John Torrey
John Torrey (August 15, 1796 – March 10, 1873) was an American botany, botanist, chemist, and physician. Throughout much of his career, he was a teacher of chemistry, often at multiple universities, while he also pursued botanical work, focusing on the flora of North America. His most renowned works include studies of the New York flora, the Mexican Boundary, the Pacific railroad surveys, and the uncompleted ''Flora of North America''.

DNA Analysis
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or through biochemical analysis to measure specific protein output. In a medical setting, genetic testing can be used to diagnose or rule out suspected genetic disorders, predict risks for specific conditions, or gain information that can be used to customize medical treatments based on an individual's genetic makeup. Genetic testing can also be used to determine biological relatives, such as a child's biological parentage (genetic mother and father) through DNA paternity testing, or be used to broadly predict an individual's ancestry. Genetic testing of plants and animals can be used for similar reasons as in humans (e.g. to assess relatedness/ancestry or predict/diagnose genetic disorders), to gain information used for selective breed ...

Hesperoyucca Newberryi
''Hesperoyucca newberryi'', commonly known as the Grand Canyon Quixote plant or Newberry's yucca, is a plant species endemic to Arizona. It is found only in Mohave and Coconino Counties, on the walls of canyons near the Colorado River. ''Hesperoyucca newberryi'' is a perennial forming a rosette. It is semelparous Semelparity and iteroparity are two contrasting reproductive strategies available to living organisms. A species is considered ''semelparous'' if it is characterized by a single reproduction, reproductive episode before death, and ''iteroparous ... (flowering once then dying).

''Hesperoyucca peninsularis'', the peninsular candle or lechuguilla, is a plant species endemic to the Baja California peninsula. It is a perennial forming a rosette. It is semelparous (flowering once then dying).Clary, Karen Husum. 2001The genus ''Hesperoyucca'' (Agavaceae) in the western United States and Mexico: New nomenclatural combinations.Sida 19(4): 839-847. Description Plants are monocarpic or polycarpic, and sometimes rhizomatous. Some form secondary rosettes at their base while others branch their caudex to produce new rosettes after flowering. Taxonomy Phylogeny and classification Although morphological characteristics and phylogenetic ITS analysis show that ''H. peninsularis'' is somewhat distinct from '' H. whipplei'', it is still widely recognized as either a form or a subspecies of ''H.'' ''whipplei''. More conclusive research shows that ''H. peninsularis'' and ''H. whipplei'' form a polytomy, and are sister to '' H. newberryi'', which is consistent with ...

Yucca Whipplei Ssp
''Yucca'' ( , YUCK-uh) is both the scientific name and common name for a genus native to North America from Panama to southern Canada. It contains 50 accepted species. In addition to yucca, they are also known as Adam's needle or Spanish-bayonet. The genus is generally classified in the asparagus family in a subfamily with the ''Agave'', though historically it was part of the lily family. The species range from small shrubby plants to tree-like giants, such as the Joshua tree. All yuccas have rosettes of leaves that taper to points and inflorescences with many flowers that are mainly cream white with thick petals. Though adapted to a wide range of climates the plants are xerophytes, ones that specialize in dry living conditions. The tight relationship between the yucca plants and their pollinators, the yucca moths from the genera ''Tegeticula'' and ''Parategeticula'', is a well known example of evolutionary mutualism. They are an important part of the ecology of North Ameri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
