Prospero Minimum
''Prospero minimum'' is an autumnal flowering plant of the family Asparagaceae, subfamily Scilloideae that is endemic to Crete, Greece. It is a diploid species in the ''Prospero autumnale'' cryptic species complex. This tiny autumn-flowering plant is among the smallest members of the squill family, with thread-like leaves less than 1 mm wide and delicate pink star-shaped flowers. It grows on limestone rubble near Imbros Gorge and was recognized as a distinct species in 2000 when scientists documented its uniquely diminutive size compared to related plants. Description The subspherical bulb, scarcely 1.8 cm long, is wrapped in a brown, papery and gives rise to just a few roots. In late summer the plant produces extremely fine, grass-like leaves only 0.5–1 mm across and up to 10 cm long; because these leaves appear before the flowers the growth habit is called . One or two wiry, leafless stems ( 4–10 cm tall then bear a loose spike () of three to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Speta
Franz Speta (22 December 1941 – 5 December 2015) was an Austrian botanist. He specialized in bulbous plants, especially the Hyacinthaceae. Career Speta worked as an apprentice for a clerk. He then studied at the University of Vienna in the Department of Botany and Zoology. He wrote among professors such as Lothar Geitler and Tschermak Woess about the "evolution and karyology of elaiosomes to fruit and seeds." In 1972, he received a Ph.D. From 1970, he was a research associate at the Upper Austrian Provincial Museum Linz, initially as Head of botany and invertebrates, from 1985 as director deputy of the National Museum and 1990 to 1991 as interim director. From 1993 to 2003 he was head of the newly founded Biology Centre of the National Museum. In 1982, he received the venia legendi of Systematic Botany at the University of Salzburg. In 1994, he became the Councilor appointed. Research The research focus of Speta was the bulbous plants, especially the Hyacinthaceae focusing ...

Seed Capsule
In botany, a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpellary) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classi ...

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or cultivar group, Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, Fungus, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), Chytridiomycota, chytrids, oomycetes, slime moulds and Photosynthesis, photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated variou ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Prospero
Prospero ( ) is a fictional character and the protagonist of William Shakespeare's ''The Tempest''. Character Twelve years before the play begins, Prospero is usurped from his position as the rightful Duke of Milan by his brother Antonio, who puts Prospero and his three-year-old daughter Miranda to sea on a "rotten carcass" of a boat to die. Prospero and Miranda survived and found exile on a small island inhabited mostly by spirits. Prospero learned sorcery from books, and uses it to protect Miranda. Before the play begins, Prospero freed the magical spirit Ariel from entrapment within "a cloven pine". Ariel is beholden to Prospero after he is freed from his imprisonment inside the pine tree. Prospero then takes Ariel as a slave. Prospero's sorcery is sufficiently powerful to control Ariel and other spirits, as well as to alter weather and even raise the dead: "Graves at my command have waked their sleepers, oped, and let 'em forth, by my so potent Art." - Act V, scene 1 ...

Scilla
''Scilla'' () is a genus of about 30 to 80 species of bulb-forming perennial plant, perennial herbaceous plants in the family Asparagaceae, subfamily Scilloideae. Sometimes called the squills in English, they are native to woodlands, subalpine zone, subalpine meadows, and seashores throughout Europe, Africa and the Middle East. A few species are also naturalized in Australasia and North America. Their flowers are usually blue, but white, pink, and purple types are known; most flower in early spring, but a few are autumn-flowering. Several ''Scilla'' species are valued as Ornamental plant, ornamental garden plants. Taxonomy Species of ''Scilla'' have been known since classical antiquity, being described by both Greek (Theophrastus (371–287 BC) and Dioscorides, Discorides (40–90 AD)) and Roman (Pliny the Elder, Pliny (23–79 AD)) writers. Theophrastus described ''Scilla hyacinthoides'' (''skilla''), and more briefly ''Scilla autumnalis, S. autumnalis'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lineage (evolution)
An evolutionary lineage is a temporal series of populations, organisms, cells, or genes connected by a continuous line of descent from ancestor to descendant. Lineages are subsets of the evolutionary tree of life. Lineages are often determined by the techniques of molecular systematics. Phylogenetic representation of lineages upright=1.4, A rooted tree of life into three ancient monophyletic lineages: archaea.html" ;"title="bacteria, archaea">bacteria, archaea, and eukaryotes based on rRNA genes Lineages are typically visualized as subsets of a phylogenetic tree. A lineage is a single line of descent or linear chain within the tree, while a clade is a (usually branched) monophyletic group, containing a single ancestor and all its descendants. Phylogenetic trees are typically created from DNA, RNA or protein sequence data. Apart from this, morphological differences and similarities have been, and still are used to create phylogenetic trees. Sequences from different individua ...

Chromosome
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are visible under a light microscope only during the metaphase of cell division, where all chromosomes are aligned in the center of the cell in their condensed form. Before this stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the jo ...

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Scilla Autumnalis
''Prospero autumnale'', the autumn squill, an autumnal flowering plant of the family Asparagaceae, subfamily Scilloideae, is found in the Mediterranean region from Portugal and Morocco east to Turkey and the Caucasus, plus Great Britain. Despite being classified as a single species, it is actually a cryptic species complex In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each oth ..., with a variety of cytotypes having been discovered which are phenotypically indistinguishable from each other. __TOC__ Synonyms *''Scilla autumnalis'' L. *''Anthericum autumnale'' (L.)

Floras
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
