Polygonaceae
The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus ''Polygonum'', and was first used by Antoine Laurent de Jussieu in 1789 in his book, ''Genera Plantarum''.Antoine Laurent de Jussieu. 1789. ''Genera plantarum: secundum ordines naturales disposita, juxta methodum in Horto regio parisiensi exaratam''. page 82. Herrisant and Barrois: Paris, France. (see ''External links'' below) The name may refer to the many swollen nodes the stems of some species have, being derived from Greek, ''poly'' meaning 'many' and ''gony'' meaning 'knee' or 'joint'. Alternatively, it may have a different derivation, meaning 'many seeds'. The Polygonaceae comprise about 1200 speciesDavid J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008).

Polygonoideae
Polygonoideae is a subfamily of plants in the family Polygonaceae. It includes a number of plants that can be highly invasive, such as Japanese knotweed, ''Reynoutria japonica'', and its hybrid with '' R. sachalinensis'', ''R.'' × ''bohemica''. Boundaries between the genera placed in the subfamily and their relationships have long been problematic, but a series of molecular phylogenetic studies have clarified some of them, resulting in the division of the subfamily into seven tribes. Taxonomy Phylogeny A 2015 molecular phylogenetic study suggested that the genera and tribes in Polygonoideae were related as shown in the following cladogram. ''Rumex'' included ''Emex'', and ''Fallopia'' was not monophyletic, with some species placed outside the main group in the tribe Polygoneae, and some others grouping with '' Pteroxygonum'', placed in the tribe Pteroxygoneae. Genera Some of the boundaries between the genera are not settled ; in particular, ''Fallopia'' is at least paraphyle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calligonum
''Calligonum'' is a genus of plants in the family Polygonaceae with about 80 species across the Mediterranean Sea region, Asia and North America. Description Plants of the genus ''Calligonum'' are shrubs, diffusely but irregularly branched, with flexuous woody branches. Leaves are simple, opposite, nearly sessile, linear or scale-like, sometimes absent or very small, linear or filiform, distinct or united with short membranous ochreae. Flowers are bisexual, solitary or in loose axillary inflorescences. Flowers have persistent, 5-parted perianths not accrescent in fruit, and 10-18 stamens with filaments connate at the base. The ovary is tetragonous. Taxonomy The genus ''Calligonum'' was first published by Carl Linnaeus in 1753. It is placed in the subfamily Polygonoideae, tribe Calligoneae, along with its sister genus, ''Pteropyrum''.

Édouard Spach
Édouard Spach (23 November 1801 – 18 May 1879) was a French botanist. The son of a merchant in Strasbourg, in 1824 he went to Paris, where he studied botany with René Desfontaines (1750–1831) and Antoine-Laurent de Jussieu (1748–1836). He then became the secretary of Charles-François Brisseau de Mirbel (1776–1854). When de Mirbel became a professor at the Muséum national d'histoire naturelle (National Museum of Natural History), he followed him and remained at the museum for the remainder of his career. He published many monographs, including ''Histoire naturelle des végétaux. Phanérogames'' ("Natural history of plants: Spermatophytes"; fourteen volumes and an atlas, Roret, Paris, 1834–1848), and with Hippolyte François Jaubert (1798–1874), ''Illustrationes plantarum orientalium'' ("Illustrations of plants of the East"; five volumes, Roret, Paris, 1842–1857). The genus ''Spachea'' was named after him by Adrien-Henri de Jussieu [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Oman
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
