The ornamental orchid species ''Phalaenopsis hieroglyphica'' ( ) is native to certain islands of The Philippines. Its flowers are creamy white with transverse markings that resemble glyphs.〔(【引用サイトリンク】url=http://whatis.techtarget.com/definition/glyph )〕 Through hybridization, growers have successfully created flowers with different shapes and colors while retaining the glyphs. Since 1975, the species has been protected under Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).〔(【引用サイトリンク】title=UNEP-WCMC Species Database: CITES-Listed Species ) See also: 〕 == Growth, habitat and cultivation == Commonly ''P. hieroglyphica'' blooms in spring, with three to four star-shaped flowers that open simultaneously and last two to three months; a well-established specimen with keikis can produce more than 50 flowers. Their fragrance is said to be faintly rose-like or strongly citrus-like. The background of the flower can be white to ochre, sometimes with a tinge of green at the tips, and the glyphs on the sepals and stamens can be cinnamon or a purple hue. The flowers are comparatively larger and the glyphs more pronounced than those of ''P. lueddemanniana''. The characteristic glyphs are retained in ''P. hieroglyphica'' hybrids. As a monopodial epiphyte, it is found growing on and hanging down from trees in shady locations on the islands of Polillo, Palawan, Mindanao (in Surigao del Norte and Surigao del Sur) and Luzon at elevations below 1700 feet (500 meters). Of its genus, this species grows in the coolest and deeply shady locations of humid forests. Not much is known about its natural habitat, including its pollinators. The species was first cultivated in England by Hugh Low & Company from a specimen delivered by collector William Boxall〔For a profile of Boxall's work as a "veteran orchidist," see: 〕 in 1887. Since 1975 this species has been considered vulnerable to extinction and listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). To protect against overcollection, an export permit is required in international trade of specimens taken from their natural habitat. Protection from loss and degradation of the natural habitat are also concerns.〔 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「Phalaenopsis hieroglyphica」の詳細全文を読む スポンサード リンク
