Barclaya
''Barclaya'' is a genus of 3 - 4 species of flowering plants of the family Nymphaeaceae. ''Barclaya'' are aquatic plants native to tropical Asia. The genus was named in honour of the American-born English brewer and patron of science Robert Barclay. Synonym Though ''Hydrostemma'' is a name that is older than the name ''Barclaya'', having been published 6 months earlier, the name ''Barclaya'' has been Conserved name, "conserved" as it was deemed being much better known than ''Hydrostemma''. Taxonomy ''Barclaya'' is sometimes given its own family status as Barclayaceae on the basis of an extended perianth tube (combined sepals and petals) arising from the top of the ovary and by stamens that are joined basally, but morphological and genetic studies support the view that ''Barclaya'' should be retained in the family Nymphaeaceae. Description Plants grow from egg-shaped tubers that produce short runners and a basal rosette of leaves. All leaves are submerged. Species References ...

Nymphaeaceae
Nymphaeaceae () is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate and tropical climates around the world. The family contains nine genera with about 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or emergent from the surface. Leaves are round, with a radial notch in '' Nymphaea'' and '' Nuphar'', but fully circular in '' Victoria'' and '' Euryale''. Water lilies are a well-studied clade of plants because their large flowers with multiple unspecialized parts were initially considered to represent the floral pattern of the earliest flowering plants, and later genetic studies confirmed their evolutionary position as basal angiosperms. Analyses of floral morphology and molecular characteristics and comparisons with a sister taxon, the family Cabombaceae, indicate, however, that the flowers of extant water lilies with the most floral parts are more d ...

Nathaniel Wallich
Nathaniel Wolff Wallich FRS FRSE (28 January 1786 – 28 April 1854) was a surgeon and botanist of Danish origin who worked in India, initially in the Danish settlement near Calcutta and later for the Danish East India Company and the British East India Company. He was involved in the early development of the Calcutta Botanical Garden, describing many new plant species and developing a large herbarium collection which was distributed to collections in Europe. Several of the plants that he collected were named after him. Early life and education Nathaniel Wallich was born in Copenhagen in 1786 as Nathan Wulff Wallich. His father Wulff Lazarus Wallich (1756–1843) was a Sephardic Jewish merchant originally from the Holsatian town Altona near Hamburg, who settled in Copenhagen late in the 18th century. His mother was Hanne née Jacobson (1757–1839). Wallich attended the Royal Academy of Surgeons in Copenhagen, where his professors trained in the botanical science included ...

Tubers
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. ''Stem tubers'' form thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots (''root tubers'') under the definition; these are found in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning "lump, bump, swelling". Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots., p. 124 Stem tubers A stem tuber forms from thickened rhizomes or stolons. The top sides of the tuber produce shoots that grow into typical stems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aqua Planta
''Aqua Planta'' is a German magazine covering aquatic plants and plants cultivated in aquariums. It is the official magazine of the "Arbeitskreis Wasserpflanzen" (Workgroup Waterplants) of the "Verband Deutscher Vereine für Aquarien- und Terrarienkunde". The magazine is published quarterly. Although it is written mostly for and by aquarium plant enthusiasts, professional botanists have occasionally used it to publish their results, including occasional descriptions of newly discovered species (for example, '' Lagenandra dewitii''). The journal is published in German, with occasional English summaries. Christel Kasselmann and Gerd Eggers are among the former editors-in-chief An editor-in-chief (EIC), also known as lead editor or chief editor, is a publication's editorial leader who has final responsibility for its operations and policies.

Indochina
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of Indian and Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred to the area as in 1804, and ...

Leaves
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper ( adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs lig ...
