	Angiosperm Phylogeny Group - Wikipedia, the free encyclopedia
		The Angiosperm Phylogeny Group is an international group of systematic botanists who have come together to try to establish a consensus view of the taxonomy of flowering plants in the light of the rapid rise of molecular systematics.
		The angiosperms or flowering plants, now technically referred to as Magnoliophyta, are one of the groups of organisms whose classification has been affected most radically as direct molecular analysis of relationships has become available.
		Independent researchers, including members of the APG, continue to publish their own views on areas of angiosperm taxonomy, and in any case no classification is ever final; it represents a consensus (often a compromise) view at a particular point in time, based on a particular state of research, and new results are always appearing.

	Flowering plant - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-21)
		The flowering plants (also angiosperms or Magnoliophyta) are one of the major groups of modern plants, comprising those that produce seeds in specialized reproductive organs called flowers, where the ovulary or carpel is enclosed.
		Based on current evidence, it is seems that the ancestors of the angiosperms and the Gnetophytes diverged from one another during the late Triassic (220-202 million years ago).
		By the late Cretaceous, angiosperms appear to have become the predominant group of land plants, and many fossil plants recognizable as belonging to modern families (including beech, oak, maple, and magnolia) appeared.

	FLOWERING PLANT FACTS AND INFORMATION
		In the other major group of seed plants, called gymnosperms, the ovule is not enclosed at pollination and the seeds are not in a true fruit, although occasionally fleshy structures may cover the seed (e.g.
		Recent studies show that the monocots are a "good" group (a holophyletic or monophyletic group), while the dicots are not (a paraphyletic group).
		Separating this group of eudicots from the rest of the (former) dicots leaves a remainder, which sometimes are called informally "palaeodicots" (the prefix "palaeo-" means old, and derives from the classic greek).

	Angiosperm Phylogeny Group - Wikipedia
		De Angiosperm Phylogeny Group is een internationale groep van plantkundigen die de systematiek van de bedektzadigen bestudeert, met name aan de hand van DNA, met gevolgen voor de taxonomie.
		De bedektzadigen (wetenschappelijke naam Angiospermae, of in het systeem van Cronquist: Magnoliophyta) oftewel bloemplanten (wetenschappelijke naam Anthophyta), is een van de groepen van organismen waarvan de classificatie de grootste invloed heeft ondervonden van DNA-analyse.
		De Angiosperm Phylogeny Group heeft onderzoekers van belangrijke instituten wereldwijd bijeen gebracht die door gezamenlijke publicaties een stabiel referentiepunt moeten bieden.

	Angiosperms (via Web-Blaster/2.11) (Site not responding. Last check: 2007-10-21)
		The angiosperms, or flowering plants, are one of the major groups of extant seed plants and arguably the most diverse major extant plant group on the planet, with at least 260,000 living species classified in 453 families (Judd et al., 2002; APG II, 2003; Soltis et al., 2005).
		Furthermore, angiosperms are crucial for human existence; the vast majority of the world's crops are angiosperms, as are most natural clothing fibers.
		It is clear, however, that angiosperms do not fall into two major groups that correspond to monocots (Liliopsida) and dicots (Magnoliopsida) of most traditional classification systems such as Cronquist (1981), Takhtajan (1997), and their predecessors.

		The Angiosperm Phylogeny Group is an international group of systematic botany who have come together to try to establish a consensus view of the taxonomy of flowering plants in the light of the rapid rise of molecular systematics.
		The first APG classification was published in 1998, a Tree of Life/Update of the Angiosperm Phylogeny Group was published in 2003 (APG, 2003), and is known as APG II 2003 or just APG II.
		Nonetheless the APG publications are increasingly regarded as an authoritative point of reference, and many botanists (including contributors) rely on them as a source for taxonomic assessments that are readily accessible and whose basis can be understood by all.

		However, new phylogenetic research (Olmstead, 2003) indicates that this family is much larger, including several genera from Scrophulariaceae, and, according to Olmstead, should be renamed Veronicaceae.
		However the Angiosperm Phylogeny Group prefers not to use this name, as it was first published in 1782, predating the APG's proposed new start date of 1789 for plant family names.

		On the basis of the results of these ground-breaking studies of plant phylogeny [1,2,3,4,5,10], large-scale phylogeny building, which is necessary for an understanding of broad patterns of biological diversity, no longer had to confront the problems previously expected to impede progress.
		An independent classification of the families of angiosperms has been published that relies largely but not exclusively on DNA sequence data [22]; this makes angiosperms the first major group of organisms to be so treated.
		The seed plants (angiosperms plus gymnosperms) are then related to the ferns and their relatives, which clearly include the horsetails and whisk ferns, groups that previously were of highly variable and speculative placements.

	When Did Angiosperms First Evolve? (Site not responding. Last check: 2007-10-21)
		The pattern of angiosperm radiation is consistent with the pattern of anthophilous insect radiation and the pattern of appearance of derived floral characters and taxa specifically associated with the most advanced anthophilous insects.
		The four main groups of insects involved in angiosperm pollination (in decreasing order of importance) are the Hymenoptera (bees), Lepidoptera (butterflies and moths), Diptera (flies), and Coleoptera (beetles).
		Angiosperms utilize the spaces created by columellae in the exine for incompatibility recognition chemicals, and the holes in the tectum (outermost wall layer) provide a path for these chemicals to interact with receptors on carpel stigmas.

		In the classification of the Angiosperm Phylogeny Group (Uppsala System) dicotyledons (dicots) have been abandoned as a formal taxon, as the majority of studies find them to be paraphyletic with respect to monocots (lilies, grasses, arums, palms, orchids, gingers, etc).
		If paraphyletic groupings are accepted a 5 family classification similar to the traditional classification (with Byttneriaceae) is possible, with the transfer of some species and genera.

	Present state of Angiospermae phylogeny (Site not responding. Last check: 2007-10-21)
		The aim of this paper is to give a general picture of the angiosperms as based on our formal botanical course (SPICHIGER, multigr.) updated with the results of molecular systematics (mainly CHASE, SOLTIS, OLMSTEAD and al., 1993; and various abstracts in the issue S83 of the American Journal of Botany, 1996).
		Since taxonomic names are still confused until a new classification of angiosperms is available, we prefer to present the flowering plants by grouping them according to their macroscopic features and their phyletic relationships, using idiosyncratic terminology.
		BURGER (1981) considers monocotyledons as the progenitor of the angiosperms, the angiospermian archetype being an herbaceous protomonocotyledonian plant with small trimerous flowers.
