Lindley System
An early system of plant taxonomy, the Lindley system, was first published by John Lindley as ''An Introduction to the Natural System of Botany'' (''Natural History'', 1830). This was a minor modification of that of de Candolle (1813). He developed this further over a number of publications, including the ''Nixus plantarum'' (1833) and a second edition of ''Natural History'' (1836), in which he introduced the concept of a higher order of taxonomic rank, the Alliances, in which he embedded the Tribes (families). He also expanded his ideas on Exogens in his entry of that name in the Penny Cyclopedia (1838). In 1839 he revised his division of the plant kingdom into classes in an article in the Botanical Register. Lindley's system culminated in the three editions of his ''Vegetable Kingdom'' (1846, 1847, 1853). The schema of the ''Natural History'' is shown on pages xxxv and xxxvii-xlviii. In the ''Vegetable Kingdom'', the schema for the first edition is on pp. lv–lxviii. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Systems Of Plant Taxonomy
This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A wiktionary:taxonomic system, taxonomic system is a coherent whole of taxonomy (biology), taxonomic judgments on circumscription (taxonomy), circumscription and placement of the considered taxa. It is only a "system" if it is applied to a large group of such taxa (for example, all the flowering plants). There are two main criteria for this list. A system must be taxonomic, that is deal with many plants, by their botanical names. Secondly it must be a system, i.e. deal with the relationships of plants. Although thinking about relationships of plants had started much earlier (see history of plant systematics), such systems really only came into being in the 19th century, as a result of an ever-increasing influx from all over the world of newly discovered plant species. The 18th century saw some early systems, which are perhaps precursors rather than full taxonomic systems. A mileston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymphaeaceae
Nymphaeaceae () is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate climate, temperate and tropical climates around the world. The family contains five genera with about 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or rising from the surface. Leaves are oval and heart-shaped in ''Barclaya''. Leaves are round, with a radial notch in ''Nymphaea'' and ''Nuphar'', but fully circular in ''Victoria (plant), Victoria'' and ''Euryale ferox, Euryale''. Water lilies are a well-studied family of plants because their large flowers with multiple unspecialized parts were initially considered to represent the floral pattern of the earliest flowering plants. Later genetic studies confirmed their evolutionary position as basal angiosperms. Analyses of floral morphology and molecular characteristics and comparisons with a sister taxon, the family Cabombaceae, indicate, h ...

Thalamiflorae
''Thalamiflorae'' is a historical grouping of dicotyledons, arranged in the De Candolle system and in the Bentham and Hooker system. This group was named and published well before internationally accepted rules for botanical nomenclature. In these systems, a family was indicated as "ordo", and modern rules of botanical nomenclature accept that as meaning a family rather than an order. rticle 18.2/sup> Family names have also since been standardized (most family names now end in -''aceae''). Previous group Polypetalae. Dome shaped plants with unexpanded flower receptacle (thalamus), polysepalous, hypogynous with a superior ovary ---- Thalamiflorae detailed view of subclass Within the dicotyledons ("classis prima ''Dicotyledoneae''") the systems recognize this as subclass 1.

Dictyogens
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are flowering plants whose seeds contain only one embryonic leaf, or cotyledon. A monocot taxon has been in use for several decades, but with various ranks and under several different names. The APG IV system recognises its monophyly but does not assign it to a taxonomic rank, and instead uses the term "monocots" to refer to the group. Monocotyledons are contrasted with the dicotyledons, which have two cotyledons. Unlike the monocots however, the dicots are not monophyletic and the two cotyledons are instead the ancestral characteristic of all flowering plants. Botanists now classify dicots into the eudicots ("true dicots") and several basal lineages from which the monocots emerged. The monocots are extremely important economically, culturally, and ecologically, and make up a majority of plant biomass used in agriculture. Common crops such as dates, onions, garlic, rice, wheat, maize, and su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
