Leaf window is a specialized leaf structure consisting of a translucent area where sunlight can enter into the interior surfaces of the plant's modified leaf where photosynthesis can occur. A leaf with such structures is known as a Fenestrated leaf. The translucent structure can appear as a large continuous patch, a variegated or reticulated region, or as numerous small spots. This structural adaptation is found in certain succulent plants native to arid climates, which allow much of the plant to remain beneath the soil surface where it is protected from desiccation of extreme winds and heat while optimizing the absorption of light by increasing the photosynthetic surface area. Carnivorous plants can also make use of fenestrations by growing traps (highly modified leaves) which use sunlight to lure and/or confuse insects and increase the effectiveness of the trap.〔http://ww2.kqed.org/science/2014/03/03/predatory-plant-lure-of-the-cobra-lily/〕 Much of the known leaf window containing species are native to South Africa and neighbouring countries. ==Species== Genus of plants with numerous species having leaf windows include: *''Cephalotus'' spp. *''Conophytum'' spp. *''Darlingtonia'' spp. *''Fenestraria'' spp. *''Frithia'' spp. *''Haworthia'' spp. *''Lithops'' spp. *''Nepenthes'' spp.; known only from N. klossii and N. aristolochioides. *''Pleiospilos'' spp. *''Sarracenia'' spp. Several other plant species have leaf windows: *''Bulbine haworthioides'' *''Bulbine mesembryanthemoides'' *''Peperomia columella'' Plants with leaf windows are sometimes known as ''window plants'', though this is also the common name used to refer to ''Fenestraria rhopalophylla''. 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「Leaf window」の詳細全文を読む スポンサード リンク
