Hibiscus Acetosella
''Hibiscus acetosella'', the cranberry hibiscus or African rosemallow, is a flowering plant of the family Malvaceae. The epithet ''acetosella'' is of Latin origin and is a diminutive of the Latin name for sorrel which comes from the sour taste experienced when eating the young leaves of both plants.Klingaman, Gerald (23 September 2011)"Plant of the Week: Red-Leafed Hibiscus, Latin: ''Hibiscus acetosella''"Division of Agriculture, University of Arkansas. ''Hibiscus acetosella'' is also known colloquially as false roselle, maroon mallow, red leaved hibiscus, and red shield hibiscus. It is one of the approximately 200–300 species that are seen in sub-tropic and tropic regions. This ornamental is usually found in abandoned fields or open areas, marshes, and forest clearings. Cranberry hibiscus is a member of a perennial group known as hardy hibiscus. In contrast to the tropical hibiscus, hardy hibiscus can tolerate colder conditions, are more vigorous, longer lasting, and have la ...

William Philip Hiern
William Philip Hiern (19 January 1839 – 28 November 1925) was a British mathematician and botanist. Life Hiern attended St. John's College, Cambridge, from 1857 to 1861 and attained a "first class degree" in mathematics. Later, in 1886, he attended Oxford University. Upon his marriage he moved to Surrey and developed an interest in botany. In 1881, Hiern moved to Barnstaple in north Devonshire, and lived at the manor house adjacent to the Barnstaple Castle mound. Hiern was quite taken with the country squire role and he assumed many public duties including those of the Lord of the Manor of Stoke Rivers, northeast of Barnstaple, and he was one of the original aldermen of the County of Devon. Contributions Hiern published over 50 works on botanical subjects. Among his chief works was the catalogue of the plants Friedrich Welwitsch had collected in Angola. Awards and honours In 1903, Hiern was elected a fellow of the Royal Society. The African figwort genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as '' Alcea'' (hollyhock), '' Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), '' Sterculia'' (250 species), '' Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae ''sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae '' sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely a ...

Sorrel
Sorrel (''Rumex acetosa''), also called common sorrel or garden sorrel, is a perennial herbaceous plant in the family Polygonaceae. Other names for sorrel include spinach dock and narrow-leaved dock ('dock' being a common name for the genus ''Rumex''). Sorrel is native to Eurasia and a common plant in grassland habitats. It is often cultivated as a leaf vegetable or herb. Description Sorrel is a slender herbaceous perennial plant about high, with roots that run deep into the ground, as well as juicy stems and arrow-shaped (sagittate) leaves. The lower leaves are in length with long petioles and a membranous ocrea formed of fused, sheathing stipules. The upper ones are sessile, and frequently become crimson. It has whorled spikes of reddish-green flowers, which bloom in early summer, becoming purplish. The species is dioecious, with stamens and pistils on different plants. Subspecies Several subspecies have been named. Not all are cultivated. * ''Rumex acetosa'' ssp. ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roselle (plant)
Roselle (''Hibiscus sabdariffa'') is a species of flowering plant in the genus ''Hibiscus'' that is native to Africa, most likely West Africa and also found in India especially Maharashtra with local name ambali. In the 16th and early 17th centuries it was spread to the West Indies and Asia, respectively, where it has since become naturalized in many places. The stems are used for the production of bast fibre and the dried cranberry-tasting calyces are commonly steeped to make a popular infusion known as carcade. Description Roselle is an annual or perennial herb or woody-based subshrub, growing to tall. The leaves are deeply three- to five-lobed, long, arranged alternately on the stems. The flowers are in diameter, white to pale yellow with a dark red spot at the base of each petal, and have a stout, conspicuous calyx at the base, wide, enlarging to and becoming fleshy and a deep crimson red as the fruit matures, which takes about six months.

Hibiscus Asper
Kenaf [etymology: Persian], ''Hibiscus cannabinus'', is a plant in the family Malvaceae also called Deccan hemp and Java jute. ''Hibiscus cannabinus'' is in the genus ''Hibiscus'' and is native to Africa, though its exact origin is unknown. The name also applies to the fibre obtained from this plant. Kenaf is one of the allied fibres of jute and shows similar characteristics.

Hibiscus Surattensis
''Hibiscus surattensis'', the bush sorrel or wild sour, is a widespread species of flowering plant in the family Malvaceae. It is native to the seasonally dry tropical (and subtropical) Old World, and has been introduced to many islands of the Indian Ocean. As the common names imply, it is eaten as a leafy green by local peoples.

Soil PH
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH 9) are rare. Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo. The optimum pH range for most plants is between 5.5 and 7.5; however, many plants have adapted to thrive at pH value ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polyphenols
Polyphenols () are a large family of naturally occurring organic compounds characterized by multiples of phenol units. They are abundant in plants and structurally diverse. Polyphenols include flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning garments. Etymology The name derives from the Ancient Greek word (''polus'', meaning "many, much") and the word phenol which refers to a chemical structure formed by attaching to an aromatic benzenoid (phenyl) ring to a hydroxyl (-OH) group as is found in alcohols (hence the ''-ol'' suffix). The term polyphenol has been in use at least since 1894. Definition The term polyphenol is not well-defined, but is generally agreed that they are natural products "having a polyphenol structure (i.e., several hydroxyl groups on aromatic rings)" including four principal classes: "phenolic acids, flavonoids, stilbenes, and lignans". *Flavonoids include flavones, flavonols, flavanols ...
