See text. Magnolia is a large Genus of about 210 Flowering plant Species in the subclass Magnolioideae of the family A flower, also known as a bloom or Blossom, is the reproductive structure found in Flowering plants (plants of the division Magnoliophyta, also Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Alexandre Brongniart (1770 &ndash 1847 was a French Chemist, Mineralogist, and Zoologist, who collaborated with Georges Cuvier on This article is about the taxonomic rank for the sequence of species in a taxonomic list see Taxonomic order In scientific classification used |
Dicotyledons, or "dicots", is a name for a group of flowering plants whose seed typically has two embryonic leaves or cotyledons. The castor oil plant, Ricinus communis, is a Plant Species of the Euphorbiaceae (the evolution of this plant family is relatively unexplored A cotyledon ("seed leaf" from Greek: κοτυληδών kotylēdōn, from κοτύλη ''kotýlē'', "cup bowl" The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group A seed (in some plants referred to as a kernel) is a small embryonic Plant enclosed in a covering called the seed coat usually with some stored A cotyledon ("seed leaf" from Greek: κοτυληδών kotylēdōn, from κοτύλη ''kotýlē'', "cup bowl" There are around 199,350 species within this group [1]. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. Flowering plants that are not dicotyledons are monocotyledons, typically having one embryonic leaf. Monocotyledons or monocots are one of two major groups of Flowering plants (angiosperms that are traditionally recognised the other being Dicotyledons
The dicotyledons no longer are regarded as a "good" group, and the names "dicotyledons" and "dicots" are no longer to be used at least in a taxonomic sense. The vast majority of the former dicots, however, form a monophyletic group called the eudicots or tricolpates. A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor Eudicots and Eudicotyledons are terms introduced by Doyle & Hotton (1991 to refer to a group of Flowering plants that had been called "tricolpates" or "non-Magnoliid These may be distinguished from all other flowering plants by the structure of their pollen. Pollen is a fine to coarse powder consisting of microgametophytes ( pollen grains) which produce the male Gametes (sperm cells of Other dicotyledons and monocotyledons have monosulcate pollen, or forms derived from it, whereas eudicots have tricolpate pollen, or derived forms, the pollen having three or more pores set in furrows called colpi.
Traditionally the dicots have been called the Dicotyledones (or Dicotyledoneae), at any rank. If treated as a class, as in the Cronquist system, they may be called the Magnoliopsida after the type genus Magnolia. In biology a type is that which fixes a name to a Taxon. Depending on the nomenclature code which is applied to the organism in question a type may be a specimen Magnolia is a large Genus of about 210 Flowering plant Species in the subclass Magnolioideae of the family In some schemes, the eudicots are treated as a separate class, the Rosopsida (type genus Rosa), or as several separate classes. Rosopsida Batsch 1788 is a Botanical name for a group of Flowering plants recognized at the rank of class The remaining dicots (palaeodicots) may be kept in a single paraphyletic class, called Magnoliopsida, or further divided. Paleodicots (sometimes spelled "palaeodicots" is an informal name used by botanists (Spichiger & Savolainen 1997 Leitch et al
Classification
The following lists are of the orders formerly placed in the dicots, giving their new placement in the APG-system and that under the older Cronquist system, which is still in wide use.

Dictionary
dicotyledon
-noun
- (botany) Any plant in what used to be the Dicotyledones (also written Dicotyledonae). Dicotyledons and monocotyledons together make up the flowering plants, the angiosperms. Examples of dicotyledons are beans, buttercups, oaks, sunflowers, etc.
