Hesperoyucca
''Hesperoyucca'' is a small genus of two recognized species of flowering plants closely related to, and recently split from, ''Yucca'', which is in the century plant subfamily within the asparagus family. Description ''Hesperoyucca'' is distinct from ''Yucca'' in having loculicidally dehiscent fruit and a scape more than 2.5 cm diameter with reflexed (not erect) bracts. The stigma is capitate, whereas those of ''Yucca'' split into three reflexed lobes. The glutinous pollen is released in a sticky mass; that of ''Yucca'' species is released as single grains.Agavaceae.com – page includes a key to''Yucca'' and the three recognized species of ''Hesperoyucca'' The genus is native to |
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 ...

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). Leaves are narrow, up to long but usually less than across. Flowering stalks are up to tall, bearing cream-colored flowers. The fruit is a dry, egg-shaped capsule about long.

Hesperoyucca Peninsularis
''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
''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 Agavoideae, 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 Rosette (botany), 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 (biology), mutualism. They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asparagaceae
Asparagaceae (), known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, '' Asparagus officinalis''. This family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, lily of the valley, and hosta, and the houseplants include snake plant, corn cane, spider plant, and plumosus fern. The Asparagaceae is a morphologically heterogenous family with the included species varying widely in their appearance and growth form. It has a cosmopolitan distribution, with genera and species contained in the family native to all continents except Antarctica. Taxonomy Early taxonomy The plant family Asparagaceae was first named, described, and published in Genera Plantarum in 1789 by the French botanist Antoine Laurent de Jussieu, who is particularly noted for his work in developing the concept of pl ...

Agavoideae
Agavoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales. It has previously been treated as a separate family, Agavaceae. The group includes many well-known desert and dry-zone types, such as the agaves and yuccas (including the Joshua tree). About 640 species are placed in around 23 genera; they are widespread in the tropical, subtropical, and warm temperate regions of the world. Description and uses Species may be succulent or not. In general, Agavoideae leaves occur as rosettes at the end of a woody stem, which may range from extremely short to tree-like heights, as in the Joshua tree. The leaves are parallel-veined, and usually appear long and pointed, often with a hardened spine on the end, and sometimes with additional spines along the margins. ''Agave'' species are used to make ''tequila, pulque,'' and ''mezcal'', while others are valued for their fibers. They are quite popular for xeriscaping, as many have showy flowers. Syste ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized Author citation (botany), author abbreviations. These were initially based on Authors of Plant Names, Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium (Australian Plant Name Index, APNI). The IPNI database is a collection of the names registered by the three cooperating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
