Heterostachys
''Heterostachys'' is a genus of flowering plants in the plant family Amaranthaceae. The two species are shrubby halophytes native to South America and Central America. Description The species of ''Heterostachys'' grow as subshrubs or low shrubs. The stems are much branched, glabrous, and not jointed. The alternate leaves are fleshy, glabrous, scale-like, stem-clasping, with very short free blades (1–2 mm). The inflorescences are orbicular to cone-like, with alternate to nearly opposite scale-like bracts, and with one free flower sitting in the axil of each bract. The flowers are bisexual. The four-lobed perianth consists of four half-connate unequal tepals. There are two stamens and an ovary with two stigmas. In fruit the perianth becomes thick and spongy. The fruit wall (pericarp) is membranous. The seed is lenticular to edge-shaped with tuberculate surface. It contains a semi-annular embryo and copious perisperm (feeding tissue).

''Spirostachys'' is a plant genus of the family Euphorbiaceae first described as a genus in 1850. It is native to Africa.Govaerts, R., Frodin, D.G. & Radcliffe-Smith, A. (2000).

Salicornioideae
The Salicornioideae are a subfamily of the flowering plant family Amaranthaceae (''sensu lato'', including the Chenopodiaceae). Important characters are succulent, often articulated stems, strongly reduced leaves, and flowers aggregated in thick, dense spike-shaped thyrses. These halophyte, halophytic plants are distributed worldwide. Many are edible (see Samphire) Description The Salicornioideae are Annual plant, annual or Perennial plant, perennial herbs, subshrubs, or low shrubs. Their stems are glabrous and often apparently jointed. The alternate or opposite leaf, leaves are fleshy, glabrous, often basally connate and stem-clasping (thus forming the joints), with missing or short free leaf blades. The spike-shaped inflorescences consist of alternate or opposite bracts, these are often connate and stem-clasping, sometimes free. In the axil of each bract, there are one to five (rarely to twelve) flowers, free or sometimes fused to each other, to the bract, and to the inf ...

Amaranthaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal aggrega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allenrolfea
''Allenrolfea'' is a genus of shrubs in the family Amaranthaceae. The genus was named for the English botanist Robert Allen Rolfe. There are three species, ranging from North America to South America. Description The species of ''Allenrolfea'' are subshrubs or shrubs with erect or decumbent growth. The stems are much branched, succulent, glabrous and appear to be articulated. The alternate leaves are sessile and stem-clasping, fleshy, glabrous, their blades reduced to small, broadly triangular scales, with entire margins and acute apex. The inflorescences are terminal spikes with spirally arranged flowers. Cymes of three or five flowers are sitting in the axils of deciduous, peltate, fleshy bracts. The flowers are bisexual. The perianth consists of 4-5 joined tepals, their lobes angled and truncate distally. There are 1-2 stamens exserting the flower and an ovary with 2(-3) stigmas. The fruit in an ovoid, compressed utricle with membranous pericarp. The erect seed is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
