Austrocylindropuntia Subulata
''Austrocylindropuntia subulata'' is a species of cactus native to the Peruvian Andes. The Latin specific epithet ''subulata'' means "awl-like", referring to the shape of the rudimentary leaves. It is also known by its common names as Eve's pin and Eve's needle. Description ''Austrocylindropuntia subulata'' can reach heights up to , with numerous branches. The elongated, slightly brittle branches are up to long. The stems are marked by rhomboid to ovate bumps in a few spiral rows. At the tip of each bump is the areole, from which grow one to four straight, grayish-white spines up to long. The awl-like rudimentary leaves are up to long. The orangy-pink flowers are up to long. The long, warty hypanthium is covered by rudimentary leaves up to long. The fruit are ovoid or club-like and sometimes thorny. They are up to long. Distribution ''A. subulata'' probably comes from the Peruvian Andes, where it is common at altitudes above . Today it has been naturalised in Argentina ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Footnotes
A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of a reference work in support of the text. Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes. In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text. Numbering and symbols In English, a footnote or endnote is normally flagged by a superscripted number immediately following that portion of the text the note references, each such footnote being numbered sequentially. Occasionally, a number between brack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Curt Backeberg
Curt Backeberg (2 August 1894 in Lüneburg, Germany – 14 January 1966) was a German horticulturist especially known for the collection and classification of cacti. Biography He travelled extensively through Central and South America, and published a number of books on cacti, including the six-volume, 4,000-page ''Die Cactaceae'', 1958–1962, and the ''Kakteenlexikon'', first appearing in 1966 and updated posthumously. Although he collected and described many new species and defined a number of new genera, much of his work was based on faulty assumptions about the evolution of cacti and was too focused on geographic distribution; many of his genera have since been reorganized or abandoned. The botanist David Hunt is quoted as saying that he "left a trail of nomenclatural chaos that will probably vex cactus taxonomists for centuries.", p. 98 Nevertheless, his observations regarding the subtle variations among cacti have proven useful for hobbyists, who continue to use many cactu ...

Centre For Agriculture And Bioscience International
CABI (legally CAB International, formerly Commonwealth Agricultural Bureaux) is a nonprofit intergovernmental development and information organisation focusing primarily on agricultural and environmental issues in the developing world, and the creation, curation, and dissemination of scientific knowledge. Overview CABI is an international not-for-profit organisation. Their work is delivered through teams of CABI scientists and key partners working in over 40 countries across the world. CABI states its mission as "improving people’s lives worldwide by solving problems in agriculture and the environment". These problems include loss of crops caused by pests and diseases, invasive weeds and pests that damage farm production and biodiversity, and lack of global access to scientific research. Funding CABI states that only 3% of its revenue comes from core funding. Donors listed in the company's 2014 financial report include the UK's Department for International Development ( ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Mediterranean Basin
In biogeography, the Mediterranean Basin (; also known as the Mediterranean Region or sometimes Mediterranea) is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation. Geography The Mediterranean Basin covers portions of three continents: Europe, Africa, and Asia. It is distinct from the drainage basin, which extends much further south and north due to major rivers ending in the Mediterranean Sea, such as the Nile and Rhône. Conversely, the Mediterranean Basin includes regions not in the drainage basin. It has a varied and contrasting topography. The Mediterranean Region offers an ever-changing landscape of high mountains, rocky shores, impenetrable scrub, semi-arid steppes, coastal wetlands, sandy beaches and a myriad islands of various shapes and sizes dotted amidst the clear blue sea.

Hypanthium
In angiosperms, a hypanthium or floral cup is a structure where basal portions of the calyx, the corolla, and the stamens form a cup-shaped tube. It is sometimes called a floral tube, a term that is also used for corolla tube and calyx tube. It often contains the nectaries of the plant. It is present in many plant families, although varies in structural dimensions and appearance. This differentiation between the hypanthium in particular species is useful for identification. Some geometric forms are obconic shapes as in toyon, whereas some are saucer-shaped as in '' Mitella caulescens''. Its presence is diagnostic of many families, including the Rosaceae, Grossulariaceae, and Fabaceae. In some cases, it can be so deep, with such a narrow top, that the flower can appear to have an inferior ovary - the ovary is below the other attached floral parts. The hypanthium is known by different common names in differing species. In the eucalypts, it is referred to as the ''gum nut''; ...

Thorns, Spines, And Prickles
In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called ''spinose teeth'' or ''spinose apical processes''), are hard, rigid extensions or modifications of leaves, roots, stems or buds with sharp, stiff ends, and generally serve the same function: physically deterring animals from eating the plant material. Description In common language the terms are used more or less interchangeably, but in botanical terms, thorns are derived shoots (so that they may or may not be branched, they may or may not have leaves, and they may or may not arise from a bud),Simpson, M.
