Roscoea × Beesiana
''Roscoea'' × ''beesiana'' is considered to be a hybrid between ''Roscoea auriculata, R. auriculata'' and ''Roscoea cautleyoides, R. cautleyoides'' which occurred in cultivation. The flowers are variable: most forms have a pale cream base colour with varying amounts of purple streaking, particularly on the lip or labellum from midsummer to early autumn. It was given the Award of Garden Merit by the Royal Horticultural Society in 2011. It is classified as being hardy throughout the British Isles. Description Like all members of the genus ''Roscoea'', it dies back each year to a short vertical rhizome, to which are attached the tuber, tuberous roots. When growth begins again, "pseudostems" are produced: structures which resemble stems but are actually formed from the tightly wrapped bases (sheaths) of its leaves. ''R.'' × ''beesiana'' is usually 48–60 cm tall, with seven to nine leaves, of which at most the lowest one consists only of a sheath. Each leaf has ...

Roscoea Auriculata
''Roscoea auriculata'' is a perennial herbaceous plant occurring in the eastern Himalayas, in Tibet, Bhutan, Nepal and Sikkim. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but ''R. auriculata'', like other species of ''Roscoea'', grows in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens. Description ''Roscoea auriculata'' is a perennial herbaceous plant.

When growth begins again, "pseudostems" are produced: structures which resemble stems but are actually formed from the tightly wrapped bases (sheaths) of its leaves. ''R. auriculata'' is usually 20–40 cm tall, with three to seven leaves. The blade of the leaf (the part free from the pseudostem) is 7.5–20 cm long by 2–2.5 cm wide. The leaf sheath is smooth (Leaf#Surface of the leaf, glabro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually surrounded by an outer whorl of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as '' Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they ...

International Code Of Nomenclature For Cultivated Plants
The ''International Code of Nomenclature for Cultivated Plants'' (ICNCP) is a guide to the rules and regulations for naming cultigens, plants whose origin or selection is primarily due to intentional human activity. It is also known as Cultivated Plant Code. Cultigens under the purview of the ICNCP include ''cultivars'', Groups (''cultivar groups''), and '' grexes''. All organisms traditionally considered to be plants (including algae and fungi) are included. Taxa that receive a name under the ''ICNCP'' will also be included within taxa named under the International Code of Nomenclature for algae, fungi, and plants, for example, a cultivar is a member of a species. Brief history The first edition of the ''ICNCP'', which was agreed in 1952 in Wageningen and published in 1953, has been followed by seven subsequent editions – in 1958 (Utrecht), 1961 (update of 1958), 1969 (Edinburgh), 1980 (Seattle), 1995 (Edinburgh), 2004 (Toronto) and 2009 (Wageningen).

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthur Kilpin Bulley
Arthur Kilpin Bulley (10 January 1861 – 3 May 1942) was a British cotton merchant and creator of the Ness Botanic Gardens. He stood for Parliament as a women's suffrage candidate in 1910. Personal life Bulley was one of the 14 children of Samuel Marshall Bulley and Mary (née Raffles). He was born in New Brighton, Cheshire, in 1861. He married Harriet Agnes Whishaw in 1890. They were both committed teetotallers and politically active. They had two children together, Agnes Lois Bulley (1901–1995) and Alfred Whishaw Bulley (born 1905). Bulley's sisters included Amy Bulley and Ella Sophia Armitage, who unusually had a university education. Career After leaving school he joined his family's cotton trading business, often travelling overseas where he developed an interest in uncommon plants. Bulley purchased 60 acres of land near Ness in Cheshire in 1898, in which he built a house and a plant nursery, opening parts of the garden for free to villagers. Bulley commissioned pla ...

Anther
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs 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 (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), 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 size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''.

Staminodes
In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''; Published by Gerald Duckworth & Co. London, 4th ed 1928 Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla. Sometimes, the staminodes are modified to produce nectar, as in the witch-hazel ''(Hamamelis)''.jin lu mei shu. Hamamelis Linnaeus, Sp. Pl. 1: 124. 1753. Flora of China 9: 32. 2003 Staminodes can be a critical characteristic for differentiating between species, for instance in the orchid genus ''Paphiopedilum'', and among the penstemons. In the case of cannas, the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements. A spectacular example of staminode is given by ''Couroupita guianensis'', a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roscoea
''Roscoea'' is a genus of perennial plants of the family (biology), family Zingiberaceae (the ginger family). While most members of the ginger family are tropical, ''Roscoea'' species are native to cooler mountainous regions of the Himalayas, China and its southern neighbours. ''Roscoea'' flowers superficially resemble orchids, although they are not related. The flowers of ''Roscoea'' have a complicated structure, in which some of the showy coloured parts are not formed by petals, but by staminodes, sterile stamens which have evolved to resemble petals. Some species are grown as ornamental plants in gardens. Description ''Roscoea'' is found from Kashmir through the Himalayas to Vietnam, extending northwards into China. There are up to 22 recognized species, of which 8 are endemic to China. Typically they grow in grassland, in Scree, screes or on the edges of deciduous woodland at heights of , coming into growth at the start of the monsoon season. Species of ''Roscoea'' are sma ...
