Dracontioides Salvianii
''Dracontioides'' is a genus of flowering plants in the family Araceae. It was long thought to contain only a single species until a second species was described in 2005. Both are endemic to Brazil. The type species of the genus is ''Dracontioides desciscens'', native to swamps in eastern Brazil. This species was originally classified by Heinrich Wilhelm Schott as belonging to Urospatha, but it was subsequently reassigned to its own genus ''Dracontioides'' by Adolf Engler. The genus is closely related to both ''Urospatha'' and '' Dracontium''. The most notable feature of the species its glossy extremely sagittate leaves with oval fenestrations. The leaves are attached to 2 meter long stalks that are intern attached to a spongy 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He ...

Dracontium
''Dracontium'' is a genus of flowering plants similar to those of ''Amorphophallus''. Unlike ''Amorphophallus'' which is found in the Old World, this genus has a New World distribution and is native to South America, Central America, southern Mexico, and the West Indies. ''Dracontium'' species can be distinguished from related genera by their inflorescence, which is smaller and unisexual. The plant has a large tuber similar to that of ''Amorphophallus'', but rounder, and with no central and circular scar mark. When ''Dracontium'' plants begin to flower, the tuber swells and smoothens.Zhu, G. h. & T. B. Croat. 2004. Revision of ''Dracontium'' (Araceae). Annals of the Missouri Botanical Garden 91(4): 593–667 Species More than 20 ''Dracontium'' species have been described: * '' Dracontium amazonense'' G.H.Zhu & Croat - Venezuela, Peru, northwestern Brazil * '' Dracontium angustispathum'' G.H.Zhu & Croat - Colombia, Peru * '' Dracontium asperispathum'' G.H.Zhu & Croat - Colombi ...

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 ...

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] |
Perforate Leaf
Perforate leaves, sometimes called fenestrate, occur naturally in some species of plants. Holes develop as a leaf grows. The size, shape, and quantity of holes in each leaf can vary greatly depending on the species and can even vary greatly within a given species. Perforation is caused by sections of leaf ceasing cell growth or by dying during an early stage in the development of the leaf. These deformations that are created earliest in the leaf development end up looking more like slashes whereas those that develop later end up looking more like holes. This trait is found in only one species in Aponogetonaceae, Aponogeton madagascariensis (Madagascar laceleaf), and a few genera in Araceae, particularly Monstera. It is not fully known what evolutionary purpose perforation serves, but there are several possibilities. Perforation could serve the purpose of reducing the variations in growth rate, minimize chances of leaves tearing in high winds or it could help to maximize the amount ...

Urospatha
''Urospatha'' is a genus of flowering plants in the family Araceae that consists of approximately 10 known species. They are found growing in South America and Central America in swamps, wet savannahs, and brackish water. The leaves of the species in this genus are upward pointing and sagittate (arrow-shaped). The inflorescences are quite unique; the spathe is mottled and elongated with a spiral twist at the end. The seeds are distributed by water and have a texture similar to cork Cork or CORK may refer to: Materials * Cork (material), an impermeable buoyant plant product ** Cork (plug), a cylindrical or conical object used to seal a container ***Wine cork Places Ireland * Cork (city) ** Metropolitan Cork, also known as G ... that allows them to float.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Heinrich Wilhelm Schott
Heinrich Wilhelm Schott (7 January 1794 in Brünn (Brno), Moravia – 5 March 1865 at Schönbrunn Palace, Vienna) was an Austrian botanist well known for his extensive work on aroids (Araceae). He studied botany, agriculture and chemistry at the University of Vienna, where he was a pupil of Joseph Franz von Jacquin (1766–1839). He was a participant in the Austrian Brazil Expedition from 1817 to 1821. In 1828 he was appointed ''Hofgärtner'' (royal gardener) in Vienna, later serving as director of the Imperial Gardens at Schönbrunn Palace (1845). In 1852 he was in charge of transforming part of palace gardens in the fashion of an English garden. He also enriched the Viennese court gardens with his collections from Brazil. He was also interested in Alpine flora, and was responsible for development of the alpinum at Schloss Belvedere in Vienna. In 2008, botanists P.C.Boyce & S.Y.Wong published '' Schottarum'', a genus of flowering plants from Borneo belonging to the family Ar ...

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...
