''Stachys'' is one of the largest genera in the flowering plant family Lamiaceae.〔Harley, R. M., et al. 2004. "Labiatae". pages 167–275. In: Kubitzki, K. (editor) and J. W. Kadereit (volume editor). ''The Families and Genera of Vascular Plants'' volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. ISBN 978-3-540-40593-1〕 Estimates of the number of species in the genus vary from about 300,〔 to about 450.〔Mabberley, D. J. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK.〕 The type species for the genus is ''Stachys sylvatica''.〔''Stachys'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below).〕 ''Stachys'' is in the subfamily Lamioideae.〔 Generic limits and relationships in this subfamily are poorly known. The distribution of the genus covers Europe, Asia, Africa, Australasia and North America. Common names include hedgenettle, heal-all, self-heal, woundwort, betony, and lamb's ears. Wood betony, ''Stachys officinalis'', was the most important medicinal herb to the Anglo-Saxons of early medieval Great Britain. The Chinese artichoke (''S. affinis''), is grown for its edible tuber.〔 Several species are cultivated as ornamentals. Woolly Betony (''S. byzantina'') is a popular decorative garden plant. ''Stachys'' was named by Linnaeus in ''Species Plantarum'' in 1753.〔Carolus Linnaeus. 1753. ''Species Plantarum'' 2:580. Laurentii Salvii. (see ''External Links'' below).〕 The name is derived from the Greek word σταχυς (''stachys''), meaning "an ear of grain",〔Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume I, page 91. CRC Press: Boca Raton; New York; Washington, DC;, USA. London, UK. ISBN 978-0-8493-2673-8 (set). (see ''External links'' below).〕 and refers to the fact that the inflorescence is often a spike. The name woundwort derives from the past use of certain species in herbal medicine for the treatment of wounds. ''Stachys'' species are used as food plants by the larvae of some Lepidoptera species, including the moths ''Coleophora auricella'', ''C. lineolea'', and ''C. wockeella'', all recorded on ''S. officinalis''. They are also widely used by the European wool carder bee (''Anthidium manicatum''), which scrape the hairs from the plant in order to use them for building their nests. == Description == ''Stachys'' is a genus of shrubs and annual or perennial herbs. The stems vary from tall, with simple, opposite, triangular leaves, long with serrate margins. In most species, the leaves are softly hairy. The flowers are long, clustered in the axils of the leaves on the upper part of the stem. The corolla is 5-lobed with the top lobe forming a 'hood', varying from white to pink, purple, red or pale yellow. 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「Stachys」の詳細全文を読む スポンサード リンク
