Iris Series Laevigatae
''Iris'' ser. ''Laevigatae'' is a series of the genus ''Iris'', in ''Iris'' subg. ''Limniris''. The series was first classified by Diels in 'Die Natürlichen Pflanzenfamilien' (Edited by H. G. A. Engler and K. Prantl) in 1930. It was further expanded by Lawrence in Gentes Herb (written in Dutch) in 1953.James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) This is a group of mainly moisture loving plants from Europe, Asia and North America. They generally need rich fertile soils, they can tolerate soils with a little lime. They generally flower between early and mid-summer. They have vigorous rhizomes and leaves. They can be easily cultivated in British gardens. The leaves have small blackish spots along the veins. This can be seen when holding the leaf up to the light or under a microscope. This trait means that the species can tolerate moist soils. They can also cross pollinate between species to create hybrids. It includes: *''Iris ensata'' Thunb. – Japanese iris, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris Ensata
''Iris ensata'', the Japanese iris or Japanese water iris (Japanese: ''hanashōbu''), formerly ''I. kaempferi'', is a species of flowering plant in the family Iridaceae, native to Japan, China, Korea and Russia, and widely cultivated as an ornamental plant. "Japanese iris" may also refer to '' I. sanguinea'' and '' I. laevigata'', both native to Japan. Description ''Iris ensata'' is an erect rhizomatous herbaceous perennial growing to tall, with strap-shaped leaves. The flower, appearing in midsummer, is purple with a flash of yellow on the falls. The bluish purple color of the flowers is an example of the copigmentation phenomenon. Habitat Widely distributed throughout the Japanese archipelago and elsewhere, ''I. ensata'' is very hardy down to . It prefers a boggy or marshy environment and soil with a low (acidic) pH. In favourable conditions it will eventually form sizable clumps. Cultivation ''Iris ensata'' is extensively grown as an ornamental plant in gardens and parks t ...

Ludwig Diels
Dr. Friedrich Ludwig Emil Diels (24 September 1874 – 30 November 1945) was a German botanist. Diels was born in Hamburg, the son of the classical scholar Hermann Alexander Diels. From 1900 to 1902 he traveled together with Ernst Georg Pritzel through South Africa, Java, Australia and New Zealand. Shortly before the First World War he travelled New Guinea and in the 1930s in Ecuador. Especially his collections of plants from Australia and Ecuador, which contained numerous holotypes, enriched the knowledge of the concerning floras. His monography on the Droseraceae from 1906 is still a standard. The majority of his collections were stored at the botanical garden in Berlin-Dahlem, whose vicedirector he had been since 1913, becoming its director in 1921 until 1945. His collections were destroyed there during an air raid in 1943. He died in Berlin on 30 November 1945. Honours Several genus of plants have been named after him including; ''Dielsantha'' (from ''Campanulaceae' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iris (plant)
''Iris'' is a flowering plant genus of 310 accepted species with showy flowers. As well as being the scientific name, ''iris'' is also widely used as a common name for all ''Iris'' species, as well as some belonging to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus '' Scorpiris'' are widely known as 'junos', particularly in horticulture. It is a popular garden flower. The often-segregated, monotypic genera '' Belamcanda'' (blackberry lily, ''I. domestica''), '' Hermodactylus'' (snake's head iris, ''I. tuberosa''), and ''Pardanthopsis'' (vesper iris, '' I. dichotoma'') are currently included in ''Iris''. Three Iris varieties are used in the Iris flower data set outlined by Ronald Fisher in his 1936 paper ''The use of multiple measurements in taxonomic problems'' as an example of linear discriminant analysis.

Iris Laevigata
''Iris laevigata'', known as Japanese iris, rabbit-ear iris, or shallow-flowered iris (Japanese: カキツバタ), is a species of flowering plant in the family Iridaceae, native to Japan. It is related to other members of ''Iris'' subgenus '' Limniris'', including other species of Japanese irises. It is found growing in shallow waters and seems to prefer marshy and still ponds, although it can also be grown in damp soil if conditions are right. Flowers are usually blue, purple or violet and have unique colour patterns including some types with predominantly white flowers with blue spots (''washino-o''), and dark purples bordered with white (''maikujaku''). Synonyms include ''I. albopurpurea'' and ''I. phragmitetorum''. Cultivation ''Iris laevigata'' differs from other Japanese irises mainly in being more dependent on water and in lacking the strong midrib of the foliage. When grown from seeds, it usually germinates in 30–545 days although even under good conditions germina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iris Pseudacorus
''Iris pseudacorus'', the yellow flag, yellow iris, or water flag, is a species of flowering plant in the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet ''pseudacorus'' means "false acorus", referring to the similarity of its leaves to those of ''Acorus calamus'' (sweet flag), as they have a prominently veined mid-rib and sword-like shape. However, the two plants are not closely related. The flower is commonly attributed with the fleur-de-lis. Description This herbaceous flowering perennial plant grows to , or a rare tall, with erect leaves up to long and broad. The flowers are bright yellow, across, with the typical iris form. The fruit is a dry capsule long, containing numerous pale brown seeds. ''I. pseudacorus'' grows best in very wet conditions, and is common in wetlands, where it tolerates submersion, low pH, and anoxic soils. The plant spreads quickly, by both rhizome and water-dispersed seed. It fills a simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris Versicolor
''Iris versicolor'' is also commonly known as the blue flag, harlequin blueflag, larger blue flag, northern blue flag, and poison flag, plus other variations of these names, and in Britain and Ireland as purple iris. It is a species of ''Iris'' native to North America, in the Eastern United States and Eastern Canada. It is common in sedge meadows, marshes, and along streambanks and shores. The specific epithet ''versicolor'' means "variously coloured". It is one of the three ''Iris'' species in the ''Iris'' flower data set outlined by Ronald Fisher in his 1936 paper "The use of multiple measurements in taxonomic problems" as an example of linear discriminant analysis. Description ''Iris versicolor'' is a flowering herbaceous perennial plant, growing high. It tends to form large clumps from thick, creeping rhizomes.

Flora Of Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea ...
