Sympetalous
Sympetaly (fused petals) is a flower characteristic that historically was used to classify a grouping of plants termed Sympetalae, but this term has been abandoned in newer molecular based classifications, although the grouping has similarity to the modern term asterids. History Sympetalae Rchb. (1828), meaning “with fused petals”, is a descriptive botanical name used in the Eichler, Engler, and Wettstein systems for a group of flowering plants (angiosperms). In this group the flowers have a separate calyx and corolla and in which the corolla petals are fused, at least at their base, a condition known as sympetaly. Prior to the phylogenic classifications of August Eichler and his successors this group corresponds to the Gamopetalae of Bentham and Hooker, gamopetaly being a synonym of sympetaly. This was one of the three divisions of dicotyledons in their system. In Eichler's ''Blüthendiagramme'', the class Dicotyleae was divided into two subclasses, the Sympetalae ( ...

Corolla (flower)
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Choripetalae
Choripetalae Eichler (1876), is a descriptive botanical name used in the Eichler and Wettstein systems for a group of flowering plants.

Primulales
Primulales was an order of flowering plants. This order was recognized in several systems with little variation in circumscription (see Bentham & Hooker, Engler and Wettstein system). In the classification system of Dahlgren the Primulales were in the superorder Primuliflorae (also called Primulanae). In the 1981 version of the Cronquist system it was an order placed in subclass Dilleniidae with the following circumscription: * order Primulales *: family Myrsinaceae *: family Primulaceae *: family Theophrastaceae The APG III system includes all the plants involved in the (expanded) order Ericales The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lia ....

Ericales
The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants (e.g., '' Sarcodes sanguinea'') and carnivorous plants (e.g., genus ''Sarracenia''). Many species have five petals, often grown together. Fusion of the petals as a trait was traditionally used to place the order in the subclass Sympetalae. Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid mycorrhiza). In addition, some families among the order are notable for their exceptional ability to accumulate aluminum. Ericales are a cosmopolitan order. Areas of distribution of ...

Diapensiales
Diapensiaceae is a small family of flowering plants, which includes 15 species in 6 genera. The genera include ''Berneuxia'' Decne. (1 species), '' Diapensia'' L. (5 species), ''Galax'' Sims (1 species), '' Pyxidanthera'' Michx. (2 species), ''Shortia'' Torr. & A.Gray (4 species), and '' Schizocodon'' Siebold & Zucc. (2 species). Members of this family have little economic importance; however, some members are cultivated by florists. Taxonomy Past literature classified Diapensiaceae as an old family, without defining the meaning of old. The name '' Diapensia'' was given to ''Diapensia lapponica'' by Linnaeus. Previously, it was the Greek name of sanicle. The family, originally including only ''Diapensia lapponica'', was named by Heinrich Friedrich Link in 1829. Concerning the interrelationships in Diapensiaceae, debate still remains regarding the recognition of ''Schizocodon'' and whether it should be separate from ''Shortia''. However, recent molecular studies support the spli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym
A synonym is a word, morpheme, or phrase that means exactly or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are all synonyms of one another: they are ''synonymous''. The standard test for synonymy is substitution: one form can be replaced by another in a sentence without changing its meaning. Words are considered synonymous in only one particular sense: for example, ''long'' and ''extended'' in the context ''long time'' or ''extended time'' are synonymous, but ''long'' cannot be used in the phrase ''extended family''. Synonyms with exactly the same meaning share a seme or denotational sememe, whereas those with inexactly similar meanings share a broader denotational or connotational sememe and thus overlap within a semantic field. The former are sometimes called cognitive synonyms and the latter, near-synonyms, plesionyms or poecilonyms. Lexicograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Rendle
Alfred Barton Rendle FRS (19 January 1865 – 11 January 1938) was an English botanist. Rendle was born in Lewisham to John Samuel and Jane Wilson Rendle. He was educated in Lewisham where he first became interested in plants, St Olave's Grammar School, Southwark and St John's College, Cambridge. He graduated with a Bachelor of Arts degree from Cambridge and Bachelor of Science from University of London in 1887. He was awarded Master of Arts degree from Cambridge in 1891 and D.Sc. degree from London in 1898. He won scholarships from his school and universities that covered most of the cost of his education and his move from Cambridge to London was prompted by a vacancy for a salaried position as an assistant in the Botanical Department of the British Museum. This made him focus on systematic botany for his career, focusing on gymnosperms, monocotyledons, and the Apetalae. In 1894 he obtained a lectureship at The Birkbeck Institute, teaching during the evenings. He was Keepe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Anton Eugen Prantl
Karl Anton Eugen Prantl (10 September 1849 – 24 February 1893), also known as Carl Anton Eugen Prantl, was a German botanist. Prantl was born in Munich, Kingdom of Bavaria The Kingdom of Bavaria (german: Königreich Bayern; ; spelled ''Baiern'' until 1825) was a German state that succeeded the former Electorate of Bavaria in 1805 and continued to exist until 1918. With the unification of Germany into the German ..., and studied in Munich. In 1870 he graduated with the dissertation ''Das Inulin. Ein Beitrag zur Pflanzenphysiologie'' (The inulin, a contribution to the plant physiology). He worked with Carl Wilhelm von Nägeli and Julius Sachs. From 1887 on, he published ''Die Natürlichen Pflanzenfamilien'' (''The Natural Plant Families'') with fellow botanist Adolf Engler, who completed the work in 1915.Sambamurty, A.V.S.S''Taxonomy of Angiosperms.''I.

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many herbaria and is followed by writers of many manuals and floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He also illustrated ''Das Pflanzenreich'' (1900–1953), ''Die P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
