Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brian Mathew
Brian Frederick Mathew MBE, VMH is a British botanist, born in the village of Limpsfield, Surrey, England. His particular area of expertise is bulbous plants, particularly ornamental bulbous plants, although he has contributed to other fields of taxonomy and horticulture. He has authored or co-authored many books on bulbs and bulbous genera which appeal to both botanists and gardeners, as well as specialist monographs on other genera, including ''Daphne'' (with Chris Brickell), ''Lewisia'', and ''Helleborus''. His work has been recognized by the British Royal Horticultural Society and the International Bulb Society. Biography Brian Mathew was born in Limpsfield, a village in Surrey, England. His parents encouraged both Brian and his sister to look after small garden plots allocated to them. He records that as his father was a very successful vegetable gardener, his own interests were more in ornamental plants. An early encounter with ''Helleborus orientalis'' may have laid the ...

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 Uniflora
''Iris uniflora'' is a species in the genus ''Iris'', it is also in the subgenus '' Limniris''. It is a rhizomatous perennial, from Russia, Mongolia, China and Korea.

RuBisCO
Ribulose-1,5-bisphosphate carboxylase-oxygenase, commonly known by the abbreviations RuBisCo, rubisco, RuBPCase, or RuBPco, is an enzyme () involved in the first major step of carbon fixation, a process by which atmospheric carbon dioxide is converted by plants and other photosynthesis, photosynthetic organisms to fuel, energy-rich molecules such as glucose. In chemical terms, it catalysis, catalyzes the carboxylation of ribulose-1,5-bisphosphate (also known as RuBP). It is probably the most abundant enzyme on Earth. Alternative carbon fixation pathways RuBisCO is important biology, biologically because it catalyzes the primary chemical reaction by which Total inorganic carbon, inorganic carbon enters the biosphere. While many autotrophic bacteria and archaea fix carbon via the reductive acetyl CoA Pathway, reductive acetyl CoA pathway, the 3-hydroxypropionate cycle, or the reverse Krebs cycle, these pathways are relatively small contributors to global carbon fixation compared t ...
