Cyperus Nutans
''Cyperus nutans'' is a sedge of the family Cyperaceae that is native to Australia, China, India, Bangladesh, south-east Asia, Malaysia, India, and Indonesia. The rhizomatous perennial sedge typically grows to a height of . The culms are three sided with sharp edges and concave sides. The culms are typically up in length and have a diameter of . The leaves are usually shorter than the culms and have a width of around . It blooms between February and July and produces brown flowers. Each compound inflorescence has six to ten primary branches up to a length of . The narrow-cylindrical spikes have a length of with a diameter. After flowering a dark brown narrow-ellipsoid to narrow-obovoid shaped nut will form. The species was first formally described by the botanist Martin Vahl in 1805 as part of the work ''Enumeratio Plantarum'', from a specimen collected in India. The only two subspecies are ''Cyperus nutans'' subsp. ''nutans'' and ''Cyperus nutans'' var. ''nutans''. The plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin Vahl
Martin Henrichsen Vahl (10 October 1749 – 24 December 1804) was a Danish-Norwegian botanist, herbalist and zoologist. Biography Martin Vahl was born in Bergen, Norway and attended Bergen Cathedral School. He studied botany at the University of Copenhagen and at Uppsala University under Carl Linnaeus. He edited ''Flora Danica'' fasc. XVI-XXI (1787–1799), ''Symbolæ Botanicæ'' I-III (1790–1794), ''Eclogæ Americanæ'' I-IV (1796–1807) and ''Enumeratio Plantarum'' I-II (1804–1805). He lectured at the University of Copenhagen Botanical Garden from 1779 to 1782. Vahl made several research trips in Europe and North Africa between 1783 and 1788. He became professor at the Society for Natural History at the University of Copenhagen in 1786 and was a full professor of botany from 1801 to his death. In 1792, he was elected a foreign member of the Royal Swedish Academy of Sciences. He died in Copenhagen, Denmark at age 55. His son Jens Vahl also became a botanist. Authorit ...

Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus ''Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culm (botany)
A culm is the aerial (above-ground) stem of a grass or sedge. It is derived from Latin 'stalk', and it originally referred to the stem of any type of plant. In horticulture or agriculture, it is especially used to describe the stalk or woody stems of bamboo, cane or grain grasses. Malting In the production of malted grains, the culms refer to the rootlets of the germinated grains. The culms are normally removed in a process known as "deculming" after kilning when producing barley malt, but form an important part of the product when making sorghum or millet Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets al ... malt. These culms are very nutritious and are sold off as animal feed.

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Global Biodiversity Information Facility
The Global Biodiversity Information Facility (GBIF) is an international organisation that focuses on making scientific data on biodiversity available via the Internet using web services. The data are provided by many institutions from around the world; GBIF's information architecture makes these data accessible and searchable through a single portal. Data available through the GBIF portal are primarily distribution data on plants, animals, fungi, and microbes for the world, and scientific names data. The mission of the GBIF is to facilitate free and open access to biodiversity data worldwide to underpin sustainable development. Priorities, with an emphasis on promoting participation and working through partners, include mobilising biodiversity data, developing protocols and standards to ensure scientific integrity and interoperability, building an informatics architecture to allow the interlinking of diverse data types from disparate sources, promoting capacity building and cat ...
