Datil Yucca
''Yucca baccata'' (datil yucca or banana yucca, also known as Spanish bayonet and broadleaf yucca) is a common species of yucca native to the deserts of the southwestern United States and northwestern Mexico, from southeastern California north to Utah, east to western Texas and south to Sonora and Chihuahua. It is also reported in the wild in Colombia. The species gets its common name "banana yucca" from its banana-shaped fruit. The specific epithet ''baccata'' means 'with berries'. Banana yucca is closely related to the ''Yucca schidigera'', the Mojave yucca, with which it is interspersed where their ranges overlap; hybrids between them occur. Description ''Yucca baccata'' is recognized by having leaves long with a blue-green color, and short or nonexistent trunks. It flowers in the spring, starting in April to July depending on locality (altitude), and the flowers range from long, in six segments, white to cream-coloured with purple shades. The flower stalk is not especia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''. Biography Torrey was born in New York City in 1796, the second child of Capt. William and Margaret (née Nichols) Torrey.Robbins, C. C. (1968). John Torrey (1796–1873), His Life & Times.

Yucca Schidigera
''Yucca schidigera'', also known as the Mojave yucca or Spanish dagger, is a perennial plant in the asparagus family Asparagaceae, native to the southwestern United States and northwestern Mexico. It is most common in the Mojave Desert, but also occurs extensively in the Sonoran Desert and west to the Pacific coast of southern California and Baja California. Description ''Yucca schidigera'' is a small evergreen tree growing to tall, with a dense crown of spirally arranged bayonet-like leaves on top of a conspicuous basal trunk. The bark is gray-brown, being covered with brown dead leaves near the top, becoming irregularly rough and scaly-to-ridged closer to the ground. The leaves are long and broad at the base, concavo-convex, thick, very rigid, and yellow-green to blue-green in color. The flowers are white, sometimes with a purple tinge, long (rarely to 7.5 cm), bell-shaped and segmented into six parts; they are produced in a compact, bulbous cluster tall at the top o ...

Sonoran Desert
The Sonoran Desert () is a hot desert and ecoregion in North America that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the Southwestern United States (in Arizona and California). It is the hottest desert in Mexico. It has an area of . In phytogeography, the Sonoran Desert is within the Sonoran floristic province of the Madrean region of southwestern North America, part of the Holarctic realm of the northern Western Hemisphere. The desert contains a variety of unique endemic plants and animals, notably, the saguaro (''Carnegiea gigantea'') and organ pipe cactus (''Stenocereus thurberi''). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin, Mojave, and Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers and cold winters). This creates an extreme contrast between aridity and moistur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mojave Desert
The Mojave Desert (; ; ) is a desert in the rain shadow of the southern Sierra Nevada mountains and Transverse Ranges in the Southwestern United States. Named for the Indigenous peoples of the Americas, indigenous Mohave people, it is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah. The Mojave Desert, together with the Sonoran Desert, Sonoran, Chihuahuan Desert, Chihuahuan, and Great Basin Desert, Great Basin deserts, form a larger List of North American deserts, North American desert. Of these, the Mojave is the smallest and driest. It displays typical basin and range topography, generally having a pattern of a series of parallel mountain ranges and valleys. It is also the site of Death Valley, which is the lowest elevation in North America. The Mojave Desert is often colloquially called the "high desert", as most of it lies between . It supports a diversity of flora and fauna. The desert supports a numb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Basin
The Great Basin () is the largest area of contiguous endorheic watersheds, those with no outlets to the ocean, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrographic, biological, floristic, physiographic, topographic, and ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature of the landform as "having no connection to the ocean". The hydrographic defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, 175 ...

Autonym (botany)
In botanical nomenclature, autonyms are automatically created names, as regulated by the ''International Code of Nomenclature for algae, fungi, and plants'' that are created for certain subdivisions of genera and species, those that include the type of the genus or species. An autonym might not be mentioned in the publication that creates it as a side-effect. Autonyms "repeat unaltered" the genus name or species epithet of the taxon being subdivided, and no other name for that same subdivision is validly published (article 22.2). For example, ''Rubus'' subgenus ''Eubatus'' is not validly published, and the subgenus is known as ''Rubus'' subgen. ''Rubus''. Autonyms are cited without an author. The publication date of the autonym is taken to be the same as that of the subdivision(s) that automatically established the autonym, with some special provisions (the autonym is considered to have priority over the other names of the same rank established at the same time (article 11.6)).

World Flora Online
World Flora Online is an Internet-based compendium of the world's plant species. Description The World Flora Online (WFO) is an open-access database, launched in October 2012 as a follow-up project to The Plant List, with the aim of publishing an online flora of all known plants by 2020. It is a project of the United Nations Convention on Biological Diversity, with goal of halting the loss of plant species worldwide by 2020. It is developed by a collaborative group of institutions around the world in response to the 2011–2020 Global Strategy for Plant Conservation (GSPC)'s updated Target 1: to produce "an online flora of all known plants". An accessible flora of all known plant species was considered a fundamental requirement for plant conservation. It provides a baseline for the achievement and monitoring of other targets of the strategy. The previous target of GSPC was achieved in 2010 with The Plant List. WFO was conceived in 2012 by an initial group of four instituti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Sweet Potato
The sweet potato or sweetpotato (''Ipomoea batatas'') is a dicotyledonous plant in the morning glory family, Convolvulaceae. Its sizeable, starchy, sweet-tasting tuberous roots are used as a root vegetable, which is a staple food in parts of the world. Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Moreover, the young shoots and leaves are occasionally eaten as greens. The sweet potato and the potato are in the order Solanales, making them distant relatives. Although darker sweet potatoes are often known as "yams" in parts of North America, they are even more distant from actual yams, which are monocots in the order Dioscoreales. The sweet potato is native to the tropical regions of South America in what is present-day Ecuador. Of the approximately 50 genera and more than 1,000 species of Convolvulaceae, ''I. batatas'' is the only crop plant of major importance—some others are used locally (e.g., ''I. aquatica'' "ka ...

Indehiscent
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part. Structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay, digestion by herbivores, or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., '' Platycodon'', '' Fuchsia''), but this is rarely referred to as dehiscence unless circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a trait that causes seed dispersal is a disadvantage for f ...
