The genus ''Ophrys'' is a large group of orchids from the alliance Orchis in the subtribe Orchidinae. They are widespread across much of Europe, North Africa, the Canary Islands, and the Middle East as far east as Turkmenistan.〔(Kew World Checklist of Selected Plant Families )〕〔(Altervista Flora Italiana, ''Ophrys'' )〕 These plants are remarkable in that they successfully reproduce through pseudocopulation, that is, their flowers mimic female insects to such a degree that amorous males are fooled into mating with the flowers, thereby pollinating them. There are many natural hybrids. They are referred to as the "bee orchids" due to the flowers of some species resemblance to the furry bodies of bees and other insects. Their scientific name ''Ophrys'' is the Greek word for "eyebrow", referring to the furry edges of the lips of several species. ''Ophrys'' was first mentioned in the book "Natural History" by Pliny the Elder (23-79 AD). == Biology == They are terrestrial or ground orchids from central to South Europe, North Africa, Asia Minor, up to the Caucasus Mountains, but mostly in the Mediterranean region. They have been said to be the most important group of European terrestrial orchids. During summer, all ''Ophrys'' orchids are dormant as underground bulbous tubers, which serve as a food reserve. In late summer/autumn they develop a rosette of leaves. Also a new tuber starts to grow and matures until the following spring; the old tuber slowly dies. The next spring the flowering stem starts to grow. During flowering the leaves have already started to wither.〔 Most ''Ophrys'' orchids are dependent on symbiotic fungi. Transplanting specimens, especially wild specimens, is difficult, sometimes impossible, due to this symbiosis unless a large amount of surrounding earth is also taken with the plant. All orchids are protected under CITES II and should not be removed or disturbed in habitat. The shiny, basal leaves have a green or bluish color. Two to twelve flowers grow on an erect stem with basal leaves.〔 These species are successfully cultivated by specialist growers of terrestrial orchids and are reported to be difficult to grow, being sensitive to rotting and damping off diseases if not properly subjected to a cool and dry aestivation period over the summer months with no water.〔 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「Ophrys」の詳細全文を読む スポンサード リンク
