''Diplarrena'' is a genus of flowering plants in the iris family, Iridaceae. The two species are endemic to Australia. The name is from Greek ''diploos'' ("double") and ''arren'' ("male"); plants in the genus have only two functional stamens, while all other Iridaceae have three. The name is often misspelled ''Diplarrhena'', an error that began with George Bentham's ''Flora Australiensis'' in 1873. These plants are tufted perennial herbs with short rhizomes. The leaves are basal, linear, flat, and present all year. The stem is erect, with a few reduced leaves. Flowers appear one at a time from a green terminal spathe. They are iris-like but distinctly zygomorphic. There are six white tepals and a style with two thread-like branches. There are two species: * ''D. moraea'' Labill. is from Tasmania, Victoria and New South Wales. It has leaves up to a centimeter wide. The flowers are 5 to 6 centimeters wide, with blunt-tipped outer tepals 1.5 to 2.5 centimeters wide. The inner tepals are often tinged or veined with purple, and are yellowish at the tips. * ''D. latifolia'' Benth. from Tasmania is a larger plant with leaves 1 to 2.2 centimeters wide. The flowers are 6 to 8 centimeters wide with strongly purple-veined, yellow-tipped inner tepals. The species may be a regional variant of ''D. moraea''. The cultivar 'Amethyst Fairy' is a large-flowered selection with darker markings on the inner tepals. ==Notes== 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「Diplarrena」の詳細全文を読む スポンサード リンク
