''Vitex'' is a genus of flowering plants in the family Lamiaceae.〔List of Genera in Lamiaceae. At: Peter F. Stevens. 2001 onwards. Angiosperm Phylogeny Website At: Missouri Botanical Garden Website. (see ''External links'' below).〕 It has about 250 species.〔Raymond M. Harley, Sandy Atkins, Andrey L. Budantsev, Philip D. Cantino, Barry J. Conn, Renée J. Grayer, Madeline M. Harley, Rogier P.J. de Kok, Tatyana V. Krestovskaja, Ramón Morales, Alan J. Paton, and P. Olof Ryding. 2004. "Labiatae" pages 167-275. In: Klaus Kubitzki (editor) and Joachim W. Kadereit (volume editor). ''The Families and Genera of Vascular Plants'' volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. ISBN 978-3-540-40593-1〕〔''Vitex'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below).〕 Common names include "chastetree", traditionally referring to ''V. agnus-castus'' but often applied to other species as well. Species of ''Vitex'' are native throughout the tropics and subtropics, with a few species in temperate Eurasia.〔(Kew World Checklist of Selected Plant Families )〕〔David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK.〕 About 18 species are known in cultivation. ''Vitex agnus-castus'' and ''Vitex negundo'' are often grown in temperate climates.〔Anthony J. Huxley, Mark Griffiths, and Margot Levy (editors). 1992. ''The New Royal Horticultural Society Dictionary of Gardening.'' The Macmillan Press Limited, London; The Stockton Press, New York.〕 About six others are frequently grown in the tropics.〔George W. Staples and Derral R. Herbst "A Tropical Garden Flora" Bishop Museum Press: Honolulu (2005)〕 Most of the cultivated species serve as ornamentals. Some provide valuable lumber. The flexible limbs of some species are used in basket weaving.〔 Some of the aromatic species are used medicinally〔 or to repel mosquitos.〔 The genus ''Vitex'' was named by Linnaeus in Species Plantarum in 1753.〔Carolus Linnaeus. 1753. ''Species Plantarum'' 2:706. Laurentii Salvii. (see ''External Links'' below).〕 ''Vitex'' was the name used by Pliny the Elder for ''Vitex agnus-castus''. It is derived from the Latin ''vieo'', meaning to weave or to tie up, a reference to the use of ''Vitex agnus-castus'' in basketry.〔Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume I, page 91. CRC Press: Boca Raton; New York; Washington, DC;, US. London, UK. ISBN 978-0-8493-2673-8 (set). (see ''External links'' below).〕 ''Vitex'' is one of several genera that was transferred from Verbenaceae to Lamiaceae in the 1990s as a result of phylogenetic studies of DNA sequences. It is the largest genus in the subfamily Viticoideae of Lamiaceae.〔 Taxon sampling in molecular phylogenetic studies has never been sufficient to test the monophyly of Viticoideae, but it is generally thought to be an unnatural group.〔Systematics of Lamiaceae Subfamily Viticoideae. At: Website of Kew Gardens. (see ''External links'' below).〕 The subfamily is probably diphyletic, with ''Premna'', ''Gmelina'', and ''Cornutia'' constituting one clade, and with ''Vitex'', ''Petitia'', ''Pseudocarpidium'', and ''Teijsmanniodendron'' constituting the other.〔Gemma L.C. Bramley, Félix Forest, and Rogier P.J. de Kok. 2009. "Troublesome tropical mints: re-examining generic limits of ''Vitex'' and relations (Lamiaceae) in South East Asia". ''Taxon'' 58(2):500-510.〕 ==Description== ''Vitex'' is a genus of shrubs and trees, from 1 to 35m tall. Some species have whitish bark that is characteristically furrowed. Leaves are opposite, usually compound. The fruit is a drupe. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vitex」の詳細全文を読む スポンサード リンク
