Aponogetonaceae
The Aponogetonaceae (the Cape-pondweed family or aponogeton family) are a family of flowering plants in the order Alismatales. In recent decades the family has had universal recognition by taxonomists. The APG system (1998) and APG II system (2003) treat it in the order Alismatales in the clade monocots. The family consists of only one genus, ''Aponogeton'', with 56 known species (Christenhusz & Byng 2016 ) of aquatic plants, most of which have been included in a molecular phylogeny by Chen et al. (2015). The name was published in '' Supplementum Plantarum'' 32: 214 (1782) and is derived from a geographic location neighboring (''geton'') the Apono tribal district of coastal Gabon. Some species are used as ornamental plants in aquariums. Distribution They are aquatic plants, which are found in tropical to warm temperate regions of Africa, Asia and Australasia.Watson, L. & Dallwitz, M. J.

Alismatales
The Alismatales (alismatids) are an order of flowering plants including about 4,500 species. Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in marine habitats. Description The Alismatales comprise herbaceous flowering plants of often aquatic and marshy habitats, and the only monocots known to have green embryos other than the Amaryllidaceae. They also include the only marine angiosperms growing completely submerged, the seagrasses. The flowers are usually arranged in inflorescences, and the mature seeds lack endosperm. Both marine and freshwater forms include those with staminate flowers that detach from the parent plant and float to the surface. There they can pollinate carpellate flowers floating on the surface via long pedicels. In others, pollination occurs underwater, where pollen may form elongated strands, increasing chance of success. Most aquatic species have a totally submerged juvenile phase, and flowers are either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aponogeton Madagascariensis
''Aponogeton madagascariensis'' is commonly known as Madagascar laceleaf, lattice leaf or lace plant. It is an aquatic plant native to Madagascar, popularly sold for use in aquariums. It is endangered in the wild. Description It is an aquatic monocotyledonous perennial plant with tuberous rhizomes in diameter. The leaves are oblong, the leaf blade 15–55 cm long and from 5–16 cm broad, with a total leaf length including the petiole of up to . The leaves spread horizontally beneath the surface of the water, and are little more than a lattice-like skeletal network of veins with no tissue between. The flowers are produced on an erect spike up to long, protruding up to above the water surface. There seem to be several forms of this plant in cultivation, some large, some much smaller. Cultivation and uses The tuberous roots are edible. It requires water temperatures of 15-26 °C and pH of 5-7.5, growing best in low light outdoors.Tropica''Aponogeton madagasc ...

Aponogeton Rigidifolius
''Aponogeton rigidifolius'' is a species of freshwater plant native to Sri Lanka. In the wild it grows in deep water at temperatures of in sandy soil with the water pH at 7.2. Description The creeping rhizome is cylindrical and about thick. The leaves stay submerse, are firm (almost leather-like and seem immune to most fish and snails) about long and wide. The margins of the leaves are flat to slightly undulate with a distinct midrib. In colour they are a dark green to reddish colour. The inflorescence has a single spike with white flowers and small fruits. Cultivation and uses This species is unique amongst the Aponogetons in having an elongated rhizome rather than a tuber; the rhizome creeps along the surface, and from it new leaves sprout. This rhizome can be divided. It needs no rest period but is slow growing, though tough once established. It needs only a moderate light, tropical temperatures, and will tolerate harder water than most other Aponogetons. It is not commonl ...

APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an orde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aponogeton Ulvaceus
''Aponogeton ulvaceus'' is a submerged aquatic plant in the Aponogetonaceae family. It has a small cone shaped, slightly hairy rhizome about in diameter. The leaf blades have a base that tapers gradually, pale green in colour (reddish under intense light), over long and broad, with a wavy margin on petioles of an equal length, and in appearance slightly translucent. A single bulb may produce up to forty leaves in good conditions. No floating leaves are formed. The yellow flowers are produced on one or two, and sometimes more, erect spikes. Origin It is distributed throughout central and northern Madagascar. In the wild, the plant is permanently submerged and grows in both still and moving waters and sunny and partially shaded environments. Cultivation and uses ''Aponogeton ulvaceus'' will tolerate most water conditions, but will thrive in slightly alkaline water conditions and a temperature of around .
