Besides the superposition of different plants growing on the same soil, there is a lateral impact of the higher layers on adjacent plant communities, for example, at the edges of forests and bushes. This particular vegetation structure results in the growth of certain vegetation types such as forest mantle and margin communities. [citation needed]
Phytogeography (from Greek φυτόν, phytón = "plant" and γεωγραφία, geographía = "geography" meaning also distribution) or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth's surface. [1]
A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735. This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a ...
The Takhtajan system and Cronquist system treat them as a division (Magnoliophyta). [citation needed] The Dahlgren system and Thorne system (1992) treat them as a class (Magnoliopsida). The APG system of 1998, and the later 2003 [7] and 2009 [8] revisions, treat the flowering plants as an unranked clade without a formal Latin name (angiosperms ...
The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors. History [ edit ]
A plant community is a collection or association [1] [page needed] of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types. The components of each plant community are influenced by soil type, topography, climate and human disturbance ...
The definition of a specific vegetation type may include not only physiognomy but also floristic and habitat aspects. [ 15 ] [ 16 ] Furthermore, the phytosociological approach in the study of vegetation relies upon a fundamental unit, the plant association , which is defined upon flora.
In plant breeding nomenclature, at least in countries that are signatory to the UPOV Convention, "variety" or "plant variety" is a legal term. [citation needed] In zoological nomenclature, the only allowed rank below that of species is that of subspecies. A name that was published before 1961 as that of a variety is taken to be the name of a ...
