Iris Scariosa
''Iris scariosa'' is a plant species in the genus ''Iris'', it is also in the subgenus ''Iris''. It is a rhizomatous perennial, from the mountainsides of Russia, Kazakhstan, Mongolia and China. It has sword-like, or sickle shaped, blue green or grey-green leaves, a short flowering stem, 3 or 4 membranous or semi-transparent flower bud leaves, 2 violet, reddish violet, lilac, blue-purple, or blue flowers in late spring, with yellow or white beards. It is cultivated as an ornamental plant in temperate regions. It was merged with another similar iris in the region, and ''Iris glaucescens'' became a synonym of ''Iris scariosa'', before being divided into two separate species again. Although some sources still call it the main species, despite a slight colour difference. Description It is similar in form to ''Iris pumila''. It has a yellow-white, thick, fleshy rhizome, that is between in diameter. Under the rhizome are secondary stolon-like roots. On top of the rhizome, are the yello ...

Matilda Smith
Matilda Smith (1854–1926) was a botanical artist whose work appeared in ''Curtis's Botanical Magazine'' for over forty years. She became the first artist to depict New Zealand's flora in depth, the first official artist of the Royal Botanic Gardens at Kew, and the second woman to become an associate of the Linnaean Society. Biography Matilda Smith was born in Bombay, India, on 30 July 1854, but her family emigrated to England when she was a small child. Her interests in botany and botanical art were fostered by her second cousin Joseph Dalton Hooker, whose daughter Harriet would also go on to become a botanical illustrator. Hooker was then the director of Kew Gardens and a talented draughtsman in his own right, and he brought Smith into the Gardens to train as an illustrator. Smith especially admired the work of Walter Hood Fitch, who was then the lead artist for ''Curtis's Botanical Magazine''. Despite her limited artistic training, Hooker encouraged her to show the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Iris Sanguinea
''Iris sanguinea'' is a rhizomatous flowering plant in the genus ''Iris'' and in the series '' Sibiricae''. It is cultivated as an ornamental plant in temperate regions. It is one of the species considered a Japanese iris. It is from Asia, found between Russia, Mongolia, China, Japan and Korea. It has grey green leaves, an unbranched flowering stem and flowers in reddish-purple shades, from blue to blue-purple, red-violet, with a rare white variant. A 2020 taxonomic revision suggests that previously distinguished taxa of ''Iris sanguinea'' and ''Iris sibirica'' bear no Phylogenetics, phylogenetic nor Morphology (biology), morphological distinction. As such, name ''I. sanguinea'' was synonymized with ''I. siberica''. Description It has a thick creeping rhizome. It has grey-green leaves that are more or less the same height as the flowering stems, but as the leaves droop, they appear shorter. The linear, narrow leaves grow between 20 and 60 cm long and 5–13 mm wide. ... [...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.

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] |
Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
