Grewia
''Grewia'' is a large flowering plant genus in the mallow family Malvaceae, in the expanded sense as proposed by the Angiosperm Phylogeny Group. Formerly, Grewia was placed in either the family Tiliaceae or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of ''Grewia'' and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, ''Grewia'' is in the subfamily Grewioideae and therein the tribe Grewieae, of which it is the type genus. The genus was named by Carl Linnaeus, in honor of the botanist Nehemiah Grew (1641-1712) from England. Grew was one of the leading plant anatomists and microscope researchers of his time, and his study of pollen laid the groundwork for modern-day palynology. Ecology and uses Several Lepidoptera caterpillars are found to feed on ''Grewia'' species. These include the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grewia Flavescens (G Pilosa)- Khatkhati In Hyderabad, AP W IMG 9130
''Grewia flavescens'', called rough-leaved raisin, sandpaper raisin, and donkey berry (a name it shares with '' Grewia bicolor''), is a species of flowering plant in the family Malvaceae, native to subSaharan Africa, Yemen, Saudi Arabia, and India. It is considered to be an underutilized crop, both for its fruit and its use for livestock forage Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term ''forage'' has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also use ....

Grewia Occidentalis
''Grewia occidentalis'', the crossberry, is a small, hardy, attractive tree indigenous to Southern Africa. Description A small, scrambling, deciduous tree reaching a height of about 3 m, its purple, star-shaped flowers appear in summer, followed by distinctive four-lobed berries (from where it gets its common names "crossberry" and "four-corner"). These shiny reddish-brown fruits remain on the tree for long periods and are favoured by fruit-eating birds. The simple leaves are shiny, deep green and sometimes slightly hairy. Distribution and Habitat Grewia occidentalis occurs naturally across south-eastern Africa, where its range extends from Cape Town along the coast to Mozambique and inland to Zimbabwe. The native habitats of the plant are extremely varied, it is found in both the arid karoo of western South Africa and from the Highveld, and across the Afromontane forests of the Drakensberg range along the eastern coastline.

Grewioideae
Grewioideae is a subfamily of the family Malvaceae and was first described by Hochreutiner. The group is named after its type genus, ''Grewia'', which is named for the English scientist Nehemiah Grew (1641-1712). It contains a number of genera that were previously placed in the defunct family Tiliaceae. Description Within the Malvaceae, this subfamily has its inflorescences opposite the leaves, the corollas are usually clawed, and there is a nectar-bearing hair carpet at the base of the petals and there are numerous dithecal stamens. The fruit is fleshy or capsular with spines, and the seeds are winged. The group is thought to have originated about 42 (± 15) million years ago. Taxonomy Ulrike Brunken & Alexandra Muellner divide the Grewioideae into two clades, the Grewia clade, Grewieae Endl. and the Apeiba clade, Apeibeae Benth., on the basis of morphological and molecular evidence. Tribes and genera The subfamily includes the following genera - accepted by Bayer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tiliaceae
Tiliaceae () is a family of flowering plants. It is not a part of the APG, APG II and APG III classifications, being sunk in Malvaceae mostly as the subfamilies Tilioideae, Brownlowioideae and Grewioideae, but has an extensive historical record of use. All through its existence the family has had a very lively history, with various authors taking very different views on what should be part of this family. As a result, it is recommended when this name is encountered to check what the author means. However, in the northern temperate regions the name is unambiguous as the only representative is '' Tilia'', the lime or linden. APG II system The APG II system, does not recognise this as a family but submerges it in the Malvaceae sensu lato, which unites the four families Bombacaceae, Malvaceae sensu stricto, Sterculiaceae and Tiliaceae. Modern botanical taxonomy, such as the relevant volume in the Kubitzki series which conforms to APG, treats most of the plants that traditiona ...

Nehemiah Grew
Nehemiah Grew (26 September 164125 March 1712) was an English plant anatomist and physiologist, known as the "Father of Plant Anatomy". Biography Grew was the only son of Obadiah Grew (1607–1688), Nonconformist divine and vicar of St Michaels, Coventry, and was born in Warwickshire. He graduated at Pembroke College, Cambridge in 1661, and ten years later took the degree of MD at Leiden University, his thesis being ''Disputatio medico-physica de liquore nervoso''. He began observations on the anatomy of plants in 1664, and in 1670 his essay, ''The Anatomy of Vegetables begun'', was communicated to the Royal Society by Bishop Wilkins, on whose recommendation he was in the following year elected a fellow. In 1672, when the essay was published, he settled in London, and soon acquired an extensive practice as a physician. In 1673 he published his ''Idea of a Phytological History'', which consisted of papers he had communicated to the Royal Society in the preceding year, and i ...

Common Nawab
''Polyura athamas'', the common nawab, is a species of fast-flying canopy butterfly found in tropical Asia. It belongs to the Charaxinae (rajahs and nawabs) in the brush-footed butterfly family (Nymphalidae). It occurs in the Himalayas from Kashmir to Sikkim, the hills of central India and the Eastern Ghats, the Western Ghats and southern India, Sri Lanka, Assam, Cachar, and via Myanmar, Cambodia and the Tenasserim Hills far into Indonesia. In August 2016 a specimen was spotted and caught in Palawan, Philippines. Description Male and female. Upperside black. Forewings and hindwings with a discal broad transverse area from below vein 4 in forewing to vein 2 on hindwing, a moderately large spot in interspace 5, a minute preapical dot beyond in interspace 6 on forewing, and a subterminal row of spots with two or three spots beyond them on the tornal angle of the hindwing, pale yellow, sometimes with an ochraceous, sometimes with a greenish tinge.

Type Genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens for ranks up to fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
