Blossfeldia Liliputiana
''Blossfeldia'' is a genus of cactus (family Cactaceae) containing only one species, ''Blossfeldia liliputiana'', native to South America in northwestern Argentina (Jujuy, Salta, Tucumán, Catamarca and Mendoza Provinces) and southern Bolivia ( Santa Cruz and Potosí Departments). It grows at 1,200–3,500 m altitude in the Andes, typically growing in rock crevices, and often close to waterfalls. It is of note as the smallest cactus species in the world, with a mature size of around 10–12 mm diameter. The flowers are white or rarely pink, 6–15 mm long and 5–7 mm diameter. The genus ''Blossfeldia'' has been divided into many separate species; however most morphological evidence supports that the genus is monotypic, and contains only ''Blossfeldia liliputiana''. The species is named after the fictional country of Lilliput, where all of the inhabitants are minute. Taxonomy The genus and species were first described in 1937 by Erich Werdermann after be ...

Erich Werdermann
Erich Werdermann (2 March 1892 – 20 April 1959) was a German botanist. Born in Berlin, Erich Werdermann was the son of the landowner Carl Werdermann. He first studied in Jena, but then switched to Friedrich Wilhelm University (now called Humboldt University of Berlin) in Berlin. In 1914 shortly before his graduation, Werdermann was enlisted in the army and in 1915 promoted to the rank of officer. After recovering from serious wounds suffered in 1918, he was able to continue his studies. The following year Werdermann graduated as a plant physiologist at Gottlieb Haberlandt. From 1919 to 1920 he worked at the Imperial Biological Institute in Berlin, where Peter Claussen (1877–1959) sparked his interest in fungi. From 1920 to 1921, Mann was a research assistant at the Imperial Health Office with Ernst Friedrich Gilg, who introduced him to the Botanical Museum Berlin-Dahlem. In 1921, he succeeded Rudolf Schlechter as the curator of mushrooms in the herbarium of the museum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which Erosion, erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Cacteae
Cacteae is a tribe of plants of the family Cactaceae found mainly in North America especially Mexico. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Description The spherical to short columnar plants grow individually or in cushions. Their size varies from dwarf (''Turbinicarpus'') to huge (''Ferocactus''). The non-segmented shoot axis is ribbed (''Echinocactus''), warty (''Coryphantha'') or ribbed-warty. The size and shape of the warts ranges from long and leafy ('' Leuchtenbergia'') to broad with flat axillae (''Turbinicarpus''). The areoles are usually oval, ribbon-like, grooved, or dimorphic. The small to medium-sized, regular to rarely bilaterally symmetrical flowers appear below the crown and open during the day. The fruits are fleshy to juicy berry-like, with a scaly to glabrous pericarp. They are bursti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Cactoideae
The Cactoideae are the largest subfamily of the cactus family, Cactaceae. Around 80% of cactus species belong to this subfamily. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Various revisions have been published since, e.g. to the tribe Hylocereeae and the tribe Echinocereeae. Classifications remained uncertain . Tribes and genera , the National Center for Biotechnology Information used the division of the subfamily into tribes shown below. Some revisions to the circumscriptions of the tribes are also shown. *Blossfeldieae **''Blossfeldia'' * Browningieae **''Armatocereus'' – ''Browningia'' – ''Neoraimondia'' – '' Stetsonia'' *Cacteae **''Acharagma'' – ''Ariocarpus'' – '' Astrophytum'' – ''Aztekium'' – ''Coryphantha'' – '' Cumarinia'' – ''Echino ...

Aril
An aril (pronounced ), also called an arillus, is a specialized outgrowth from a seed that partly or completely covers the seed. An arillode or false aril is sometimes distinguished: whereas an aril grows from the attachment point of the seed to the ovary (from the funiculus or '' hilum''), an arillode forms from a different point on the seed coat. The term "aril" is sometimes applied to any fleshy appendage of the seed in flowering plants, such as the mace of the nutmeg seed. Arils and arillodes are often edible enticements that encourage animals to transport the seed, thereby assisting in seed dispersal. Pseudarils are aril-like structures commonly found on the pyrenes of Burseraceae species that develop from the mesocarp of the ovary. The fleshy, edible pericarp splits neatly in two halves, then falling away or being eaten to reveal a brightly coloured pseudaril around the black seed. The aril may create a fruit-like structure, called (among other names) a ''false fruit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stoma
In botany, a stoma (from Greek ''στόμα'', "mouth", plural "stomata"), also called a stomate (plural "stomates"), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening. The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture. Air, containing oxygen, which is used in respiration, and carbon dioxide, which is used in photosynthesis, passes through stomata by gaseous diffusion. Water vapour diffuses through the stomata into the atmosphere in a process called transpiration. Stomata are present in the sporophyte generation of all land plant groups except liverworts. In vascular plants the number, size and distribution of stomata varies widely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oreste Marsoner
''Oreste'' ("Orestes", HWV A11, HG 48/102) is an opera by George Frideric Handel in three acts. The libretto was anonymously adapted from Giangualberto Barlocci’s ''L’Oreste'' (1723, Rome), which was in turn adapted from Euripides' ''Iphigeneia in Tauris''.Hicks The opera is a ''pasticcio'' ( pastiche), meaning that the music of the arias was assembled from earlier works, mainly other operas and cantatas also by Handel. The recitatives and parts of the dances are the only parts composed specifically for this work. Handel had put together similar works before, fitting the music of pre-existent arias to new words, but this was the first time he had made an opera in this way using entirely his own music. He assembled a collection of his arias from the previous years, ranging from '' Agrippina'' of 1709 to ''Sosarme'' of 1732, binding the pre-existent music seamlessly together with the newly-written recitatives to create a new musical drama. The opera is in Italian, althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lilliput And Blefuscu
Lilliput and Blefuscu are two fictional island nations that appear in the first part of the 1726 novel ''Gulliver's Travels'' by Jonathan Swift. The two islands are neighbours in the South Indian Ocean, separated by a channel wide. Both are inhabited by tiny people who are about one-twelfth the height of ordinary human beings. Both are empires, i.e. realms ruled by an emperor. The capital of Lilliput is Mildendo. In some pictures, the islands are arranged like an egg, as a reference to their egg-dominated histories and cultures. Location Swift gives the location of Lilliput and Blefuscu in Part I of ''Gulliver's Travels'', both in the text and with a map, though neither correspond to real-world geography, even as it was known in Swift's time. The text states that Gulliver's ship (the ''Antelope'') was bound for the East Indies when it was caught in "a violent storm to the northwest of Van Diemen's Land" (Tasmania). He gives the latitude as 30°2'S, though the longitude is u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
