Urticaceae
The Urticaceae are a family, the nettle family, of flowering plants. The family name comes from the genus '' Urtica''. The Urticaceae include a number of well-known and useful plants, including nettles in the genus ''Urtica'', ramie (''Boehmeria nivea''), māmaki ('' Pipturus albidus''), and ajlai ('' Debregeasia saeneb''). The family includes about 2,625 species, grouped into 53 genera according to the database of the Royal Botanic Gardens, Kew and Christenhusz and Byng (2016). The largest genera are '' Pilea'' (500 to 715 species), '' Elatostema'' (300 species), '' Urtica'' (80 species), and '' Cecropia'' (75 species). '' Cecropia'' contains many myrmecophytes. Urticaceae species can be found worldwide, apart from the polar regions. Description Urticaceae species can be shrubs (e.g. '' Pilea''), lianas, herbs (e.g. '' Urtica'', '' Parietaria''), or, rarely, trees ('' Dendrocnide'', '' Cecropia''). Their leaves are usually entire and bear stipules. Urticating (stinging) h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Ludwig Blume
Charles Ludwig de Blume or Karl Ludwig von Blume (9 June 1796, Braunschweig – 3 February 1862, Leiden) was a Germany, German-Netherlands, Dutch botanist. He was born at Braunschweig in Germany, but studied at Leiden University and spent his professional life working in the Dutch East Indies and in the Netherlands, where he was Director of the Rijksherbarium (state herbarium) at Leiden. His name is sometimes given in the Dutch language form Karel Lodewijk Blume, but the original German language, German spelling is the one most widely used in botanical texts: even then there is confusion, as he is sometimes referred to as K.L. Blume (from Karl). He carried out extensive studies of the flora (plants), flora of southern Asia, particularly in Java (island), Java, then a colony of the Netherlands. From 1823 to 1826 Blume was Deputy Director of Agriculture at the Bogor Botanical Gardens, botanic garden in Bogor (Buitenzorg) in Java. In 1827 he became correspondent of the Royal Nethe ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Section (botany)
In botany, a section ( la, sectio) is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections may in turn be divided into subsections.Article 4 in Sections are typically used to help organise very large genera, which may have hundreds of species. A botanist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making new combinations, i.e. many new binomial names for the species involved. Examples: * '' Lilium'' sectio ''Martagon'' Rchb. are the Turks' cap lilies * '' Plagiochila aerea'' Taylor is the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen( ... of ''Plagiochila'' sect.

Pilea
''Pilea'', with 600–715 species, is the largest genus of flowering plants in the nettle family Urticaceae. It is distributed throughout the tropics, subtropics, and warm temperate regions (with the exception of Australia and New Zealand). Description The majority of species are succulent shade-loving herbaceous plants or shrubs, which are easily distinguished from other Urticaceae by the combination of opposite leaves (with rare exceptions) with a single ligulate intrapetiolar stipule in each leaf axil and cymose or paniculate inflorescences (again with rare exceptions). Uses ''Pilea'' is of little economic importance; one species is used in Chinese traditional medicine (''P. plataniflora''). Horticulture Six species have horticultural value (''P. cadierei'', ''P. grandifolia'', ''P. involucrata'', ''P. microphylla'', ''P. nummulariifolia'', and ''P. peperomioides''), Some pileas are grown for their ornamental foliage which is shaped like lily-pads.
