Ophrys apifera Huds.

국표에 없다.

Ophrys apifera, known in Europe as the bee orchid, is a perennial herbaceous plant of the family Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, as well as of a highly selective and highly evolved plant–pollinator relationship.

Description

Illustration of leaf and flower morphology for Ophrys apifera.

Ophrys apifera grows to a height of 15–50 centimetres (6–20 in). This hardy orchid develops small rosettes of leaves in autumn that continue to grow slowly during winter. Basal leaves are ovate or oblong-lanceolate, and upper leaves and bracts are ovate-lanceolate and sheathing. Leaves exhibit parallel venation. The plant blooms from mid-April in continental Europe, but in the United Kingdom it flowers June to July. A flower spike is produced, composed from one to twelve flowers. Three large, purple sepals surround the base of the flower, which can easily be mistaken for petals. The true petals lie just above the sepals as two short, pubescent green structures protruding laterally from a central column. A third, modified petal, the labellum, sits at the bottom of the column as a landing pad for pollinators. The labellum is trilobed, with two pronounced humps on the hairy lateral lobes and a hairy median lobe having a pattern that mimics the abdomen of a bee. The pattern of labellum colouration is quite variable.

The central column is an adaptation unique to orchids, in which the stamens and pistil fused together to form one central rib. The anther cap can be found at the top, dorsal side of the column, while the stigma is hidden below on the ventral side. Two pollinia hang from the column over the labellum.

Distribution

Ophrys apifera is widespread across central and southern Europe, as well as North Africa and the Middle East. Its range stretches from Portugal, Ireland and Denmark east to Iran and the Caucasus. It is quite common in the Mediterranean region eastwards to the Black Sea, (Codes)  but is less common in its northern range being uncommon or local in Germany and Ireland.

In the United Kingdom, it has a distinct southeastern preference, being more common in England. Recently it has been found in the southwest of England in Butleigh near Glastonbury in Somerset and Dorchester, Dorset; whereas it is only to be found in coastal regions of Wales as well as the Hodbarrow Nature Reserve in Millom, Cumbria, and some parts of Northern Ireland. It is relatively common in the northeast of England and in recent years large numbers have appeared in the grass verges surrounding the Metro Centre in Gateshead.[7] In Scotland, it was thought to be extinct, but was rediscovered in Ayrshire in 2003. In some countries the plants have protected status. They are unusual in that in some years they appear in great numbers, then sometimes only reappear after an absence of many years.

The genus Ophrys is the most species-rich (i.e. diverse) genus of orchids in Europe and the Mediterranean with over 200 species, according to Orchids of Britain and Europe by Pierre Delforge.
