Paeonia Delavayi
''Paeonia delavayi'' is a low woody shrub belonging to the peonies, that is endemic to China. The vernacular name in China is 滇牡丹 (diān mǔdan). In English it is called Delavay's tree peony, Delavay peony, Dian peony, and dian mu dan. It mostly has red brown to yellow, nodding flowers from mid May to mid June. The light green, delicate looking deciduous leaves consist of many segments, and are alternately arranged on new growth. Description ''Paeonia delavayi'' is a deciduous hairless shrub of ¼-1¾ m high. Plants have creeping stolons and the roots are thick because they are fused together. It mainly reproduces by growing into large clones like this. Young twigs are light green, or tinged purple, rarely branching, erect, generally on top of perennial, stick-like, grayish to light brown stems. In lower plants, woody parts may not be present above ground. Like all diploid peonies, it has ten chromosomes (2n=10). Leaves The leaves are arranged alternately around ...

Adrien René Franchet
Adrien René Franchet (21 April 1834 in Pezou – 15 February 1900 in Paris) was a French botanist, based at the Paris Muséum national d'Histoire naturelle. He is noted for his extensive work describing the flora of China and Japan, based on the collections made by French Catholic missionaries in China, Armand David, Pierre Jean Marie Delavay, Paul Guillaume Farges, Jean-André Soulié, and others. He was the taxonomic author of many plants, including a significant number of species from the genera ''Primula'' and ''Rhododendron''. The following genera are named in his honor: * '' Franchetella'', family Sapotaceae, named by Jean Baptiste Louis Pierre. * '' Franchetia'', family Rubiaceae, named by Henri Ernest Baillon. *''Sinofranchetia'', family Lardizabalaceae, named by William Botting Hemsley.

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Achille Eugène Finet
Achille Eugène Finet (1863, Argenteuil – 1913, París) was a French botanist best known for his study of orchids native to Japan and China. Within the family Orchidaceae, he was the taxonomic authority of the genera '' Arethusantha'', ''Hemihabenaria'', '' Monixus'' and '' Pseudoliparis'' as well as of numerous orchid species. With François Gagnepain, he circumscribed a number of plant species from the family Annonaceae. In 1925 Hu Xiansu named the orchid genus '' Neofinetia'' in his honor. Selected works * ''Orchidées nouvelles de la Chine'', 1897 - New orchids native to China. * ''Sur le genre Oreorchis Lindley'', 1897 - On the genus ''Oreorchis'' Lindl.. * ''Orchidées recueillies au Yunnan et au Laos'', 1898 - Orchids collected in Yunnan and Laos. * ''Les orchidées du Japon, principalement d'après les collections de l'herbier du Muséum d'histoire naturelle de Paris'', 1900 - Orchids of Japan, principally from herbarium collections at the Muséum d'histoire ...

Père Jean Marie Delavay
Père Jean-Marie Delavay (28 December 1834 – 31 December 1895) was a French missionary, explorer and botanist. He was perhaps the first Western explorer of the region which is now encompassed by the ''Three Parallel Rivers of Yunnan Protected Areas''. Delavay was born in Les Gets, Haute-Savoie, in 1834. As a missionary for Missions Etrangères de Paris (Foreign Missions of Paris) he was sent to China in 1867, serving first in Guangdong, then moving to north-western Yunnan. While in France in 1881, on a break from his duties, Delavay met the natural history collector and fellow missionary Père Armand David, who had made his final collecting expedition in China in the 1870s. David encouraged Delavay to continue his collecting work and send specimens to the Paris Museum of Natural History. In 1888 he contracted bubonic plague; he survived the initial onslaught of the disease, but never fully recovered. This did not stop his explorations, however, eventually he travelled to Hon ...

Maroon
Maroon ( US/ UK , Australia ) is a brownish crimson color that takes its name from the French word ''marron'', or chestnut. "Marron" is also one of the French translations for "brown". According to multiple dictionaries, there are variabilities in defining the color maroon. The ''Cambridge English Dictionary'' defines maroon as a dark reddish-purple color while its "American Dictionary" section defines maroon as dark brown-red. This suggests slight perceptual differences in the U.K. versus North America. Lexico online dictionary defines maroon as a brownish-red. Similarly, Dictionary.com defines maroon as a dark brownish-red. The ''Oxford English Dictionary'' describes maroon as "a brownish crimson (strong red) or claret (purple color) color," while the Merriam-Webster online dictionary simply defines it as a dark red. In the sRGB color model for additive color representation, the web color called maroon is created by turning down the brightness of pure red to about ...

Paeonia Ludlowii
''Paeonia ludlowii'', is a medium high, deciduous shrub, belonging to the peonies, that is endemic to southeast Tibet. In Tibet it is known as lumaidao meaning "God’s flower". The vernacular name in Chinese is 大花黄牡丹 (da hua huang mu dan) meaning "big yellow-flowered peony". In English it is sometimes called Tibetan tree peony or Ludlow's tree peony. It has pure yellow, slightly nodding, bowl-shaped flowers, and large, twice compounded, light green leaves. Description ''P. ludlowii'' is a hairless, deciduous shrub of 2-3½ m high. It has ten chromosomes (2n=10). Stems and leaves The roots get narrower further down and are not fused together. There are no creeping stems (or stolons). The grey to light brown stems grow in clumps (or caespitose), do not branch often, remain approximately the same width during the growing season, and after some years may reach 4 cm in diameter. Young stems are light green, with at their base eight to twelve scales. Leaves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Form (botany)
In botanical nomenclature, a ''form'' (''forma'', plural ''formae'') is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the taxon: a genus name, a specific epithet, and an infraspecific epithet. The abbreviation "f." or the full "forma" should be put before the infraspecific epithet to indicate the rank. It is not italicised. For example: * '' Acanthocalycium spiniflorum'' f. ''klimpelianum'' or ** ''Acanthocalycium spiniflorum'' forma ''klimpelianum'' (Weidlich & Werderm.) Donald * ''Crataegus aestivalis'' (Walter) Torr. & A.Gray var. ''cerasoides'' Sarg. f. ''luculenta'' Sarg. is a classification of a plant whose name is: ** ''Crataegus aestivalis'' (Walter) Torr. & A.Gray f. ''luculenta'' Sarg. A form usually designates a group with a noticeable mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Follicle (fruit)
In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. It is usually defined as dehiscing by a suture in order to release seeds, for example in ''Consolida'' (some of the larkspurs), peony and milkweed (''Asclepias''). Some difficult cases exist however, so that the term indehiscent follicle is sometimes used, for example with the genus ''Filipendula'', which has indehiscent fruits that could be considered intermediate between a (dehiscent) follicle and an (indehiscent) achene. An aggregate fruit that consists of follicles may be called a follicetum. Examples include hellebore, aconite, ''Delphinium'', ''Aquilegia'' or the family Crassulaceae, where several follicles occur in a whorl on a shortened receptacle, or ''Magnolia'', which has many follicles arranged in a spiral on an elongated receptacle. The follicles of some species dehisce by the ventral suture (as in ''Banksia''), or by the dorsal suture (as in ''Magnolia'').Kapil, R. ...

Ovule
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the ''integument'', forming its outer layer, the ''nucellus'' (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center. The female gametophyte — specifically termed a ''megagametophyte''— is also called the ''embryo sac'' in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a ''funiculus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpel
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ...
