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 Sc ...

Bulb
In botany, a bulb is structurally a short stem with fleshy leaves or leaf basesBell, A.D. 1997. ''Plant form: an illustrated guide to flowering plant morphology''. Oxford University Press, Oxford, U.K. that function as food storage organs during dormancy. (In gardening, plants with other kinds of storage organ are also called "ornamental bulbous plants" or just "bulbs".) Description The bulb's leaf bases, also known as scales, generally do not support leaves, but contain food reserves to enable the plant to survive adverse conditions. At the center of the bulb is a vegetative growing point or an unexpanded flowering shoot. The base is formed by a reduced stem, and plant growth occurs from this basal plate. Roots emerge from the underside of the base, and new stems and leaves from the upper side. Tunicate bulbs have dry, membranous outer scales that protect the continuous lamina of fleshy scales. Species in the genera ''Allium'', ''Hippeastrum'', '' Narcissus'', and ''Tulipa' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scilloideae
Scilloideae (named after the genus ''Scilla'', "squill") is a subfamily of bulbous plants within the family ''Asparagaceae''. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus ''Hyacinthus''. Scilloideae or Hyacinthaceae include many familiar garden plants such as ''Hyacinthus'' (hyacinths), ''Hyacinthoides'' (bluebells), ''Muscari'' (grape hyacinths) and ''Scilla'' and ''Puschkinia'' (squills or scillas). Some are important as cut flowers. Scilloideae are distributed mostly in Mediterranean climates, including South Africa, Central Asia and South America. Their flowers have six tepals and six stamens with a superior ovary, which previously placed them within the lily family (Liliaceae), and their leaves are fleshy, mucilaginous, and arranged in a basal rosette. The Scilloideae, like most lily-like monocots, were at one time placed in a very broadly defined lily family (Liliaceae). The subfamily is recognized in modern classification syst ...

University Of Vienna
The University of Vienna (german: Universität Wien) is a public research university located in Vienna, Austria. It was founded by Duke Rudolph IV in 1365 and is the oldest university in the German-speaking world. With its long and rich history, the university has developed into one of the largest universities in Europe, and also one of the most renowned, especially in the Humanities. It is associated with 21 Nobel prize winners and has been the academic home to many scholars of historical as well as of academic importance. History From the Middle Ages to the Enlightenment The university was founded on March 12, 1365, by Rudolf IV, Duke of Austria, hence the name "Alma Mater Rudolphina". After the Charles University in Prague and Jagiellonian University in Kraków, the University of Vienna is the third oldest university in Central Europe and the oldest university in the contemporary German-speaking world; it remains a question of definition as the Charles University in Prague ...

Lothar Geitler
Lothar Geitler (18 May 1899 – 1 May 1990) was an Austrian botanist and cytologist. He was born in Vienna. His main research interests included blue-green algae (Cyanophyta), diatoms, lichen symbioses and chromosome structure. The cyanobacteria Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blu ... genus '' Geitlerinema'' was named in his honour in 1989.

Ornithogalum
''Ornithogalum'' is a genus of perennial plants mostly native to southern Europe and southern Africa belonging to the family Asparagaceae. Some species are native to other areas such as the Caucasus. Growing from a bulb, species have linear basal leaves and a slender stalk, up to 30 cm tall, bearing clusters of typically white star-shaped flowers, often striped with green. The common name of the genus, star-of-Bethlehem, is based on its star-shaped flowers, after the Star of Bethlehem that appears in the biblical account of the birth of Jesus. The number of species has varied considerably, depending on authority, from 50 to 300. Description ''Ornithogalum'' species are perennial bulbous geophytes with basal leaves. ''Sensu lato'', the genus has the characteristics of the tribe Ornithogaleae as a whole, since the tribe is monotypic in that sense. ''Sensu stricto'', the genus is characterised by long linear to oblong-lanceolate (lance-shaped) leaves, sometimes with a white ...

Antirrhineae
The Antirrhineae are one of the 12 tribes of the family Plantaginaceae. It contains the toadflax relatives, such as snapdragons. Description and uses Most Antirrhineae are herbaceous, short-lived, perennial or annual plants growing at most about a metre/yard tall when in full flower; the maximum height of most species is half as much or less. Some are prostrate or twining. The flowers are often conspicuous, tubular with a basal appendix (spur, gibbous, or saccate) containing nectaries, and may be of any color, though yellow and blue/purple hues are most common. Multicolored flowers are a common occurrence in this tribe; a typical pattern is one conspicuous whitish or bright yellow or reddish spot at the lower outer edge of the flower tube, looking like a protruding tongue. Other characters include poricidal dehiscent capsule fruit, and the possession of iridoid glycosides. The Antirrhineae are not noted as food- or fodder plants, probably due to the iridoid content making ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrophulariaceae
The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as shrubs. Flowers have bilateral (zygomorphic) or rarely radial (actinomorphic) symmetry. The Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. The family name is based on the name of the included genus ''Scrophularia'' L. Taxonomy In the past, it was treated as including about 275 genera and over 5,000 species, but its circumscription has been radically altered since numerous molecular phylogenies have shown the traditional broad circumscription to be grossly polyphyletic. Many genera have recently been transferred to other families within the Lamiales, notably Plantaginaceae and Orobanchaceae, but also several new families. - on linhere/ref> Several families of the Lamiales have had their circumscriptions enlarged to accommodate genera transferred from t ...

Pinguicula
''Pinguicula'', commonly known as the butterworts, is a genus of carnivorous flowering plants in the family Lentibulariaceae. They use sticky, glandular leaves to lure, trap, and digest insects in order to supplement the poor mineral nutrition they obtain from the environment. Of the roughly 80 currently known species, 13 are native to Europe, 9 to North America, and some to northern Asia. The largest number of species is in South and Central America. Etymology The name ''Pinguicula'' is derived from a term coined by Conrad Gesner, who in his 1561 work entitled ''Horti Germaniae'' commented on the glistening leaves: ''"propter pinguia et tenera folia…"'' (Latin ''pinguis'', "fat"). The common name "butterwort" reflects this characteristic. Characteristics The majority of ''Pinguicula'' are perennial plants. The only known annuals are ''P. sharpii'', ''P. takakii'', ''P. crenatiloba'', and ''P. pumila''. All species form stemless rosettes. Habitat Butterworts can be ...
