Boswellia Serrata, B. Serrata
''Boswellia'' is a genus of trees in the order Sapindales, known for its fragrant resin. The biblical incense frankincense is an extract from the resin of the tree ''Boswellia sacra'', and is now produced also from '' B. frereana''. ''Boswellia'' species are moderate-sized flowering plants, including both trees and shrubs. Description ''Boswellia'' species are dioecious,Judd, W.S., Campbell, C.S., Kellogg, E.A., Stevens, P.F., and M.J. Donoghue. 2008. ''Plant Systematics: A Phylogenetic Approach'' 3rd ed. Sinauer Associates, Inc., Sunderland, Massachusetts. or hermaphroditic. The flowers may have four or five faintly connate but imbricate sepals with an equal number of distinct, imbricate petals. Also, the stamens, that may contain nectar discs, have distinct glabrous filaments that occur in one or two whorls and in numbers equaling or twice the number of petals; the tricolporate pollen is contained within two locules of the anthers that open longitudinally along slits.

William Roxburgh
William Roxburgh FRSE FRCPE Linnean Society of London, FLS (3/29 June 1751 – 18 February 1815) was a Scottish people, Scottish surgeon and botanist who worked extensively in India, describing species and working on economic botany. He is known as the founding father of Indian botany. He published numerous works on Indian botany, illustrated by careful drawings made by Indian artists and accompanied by taxonomic descriptions of many plant species. Apart from the numerous species that he named, many species were named in his honour by his collaborators. He was the first to document the existence of the Ganges river dolphin. Early life He was born on 3 June 1751 on the Underwood estate near Craigie, South Ayrshire, Craigie in Ayrshire and christened on 29 June 1751 at the nearby church at Symington, South Ayrshire, Symington. His father may have worked in the Underwood estate or he may have been the illegitimate son of a well-connected family. His early education was at Underwood ...

Boswellia Ameero
''Boswellia ameero'' is a species of flowering plant in the Burseraceae family. It is endemic to the island of Socotra in Yemen, common locally in arid, partly deciduous forests; however, populations are fragmentary, with aged, seldom regenerating trees being dominant. Also, the habitat of ''B. ameero'' may be degrading. Flowers of ''B. ameero'' vary; in some populations they are bright pink, in others, pale pink. ''Boswellia ameero'' is sometimes used for its resin A resin is a solid or highly viscous liquid that can be converted into a polymer. Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds, predominantly terpenes. Commo ....

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

James Boswell
James Boswell, 9th Laird of Auchinleck (; 29 October 1740 ( N.S.) – 19 May 1795), was a Scottish biographer, diarist, and lawyer, born in Edinburgh. He is best known for his biography of the English writer Samuel Johnson, '' Life of Samuel Johnson,'' which is commonly said to be the greatest biography written in the English language. A great mass of Boswell's diaries, letters, and private papers were recovered from the 1920s to the 1950s, and their publication by Yale University has transformed his reputation. Early life Boswell was born in Blair's Land on the east side of Parliament Close behind St Giles' Cathedral in Edinburgh on 29 October 1740 ( N.S.). He was the eldest son of a judge, Alexander Boswell, Lord Auchinleck, and his wife Euphemia Erskine. As the eldest son, he was heir to his family's estate of Auchinleck in Ayrshire. Boswell's mother was a strict Calvinist, and he felt that his father was cold to him. As a child, he was delicate. Kay Jamison, Profes ...

John Boswell (botanist)
John Eastburn Boswell (March 20, 1947December 24, 1994) was an American historian and a full professor at Yale University. Many of Boswell's studies focused on the issue of religion and homosexuality, specifically Christianity and homosexuality. Much of his work addressed the history of marginalized groups, particularly in the context of religion and sexuality. His first book, ''The Royal Treasure: Muslim Communities Under the Crown of Aragon in the Fourteenth Century'', appeared in 1977. In 1994, Boswell's fourth book, ''Same-Sex Unions in Pre-Modern Europe'', was published. He died that same year from AIDS-related complications. Biography Early life Boswell was born on March 20, 1947, in Boston, Massachusetts, the son of Colonel Henry Boswell Jr. and Catharine Eastburn Boswell. He earned his BA at the College of William & Mary, and his PhD at Harvard University before being hired to teach at Yale University.

Drupe
In botany, a drupe (or stone fruit) is a type of fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pip'' (UK), ''pit'' (US), ''stone'', or ''pyrena'') of hardened endocarp with a seed (''kernel'') inside. Drupes do not split open to release the seed, i.e., they are dehiscence (botany), indehiscent. These fruits usually develop from a single carpel, and mostly from flowers with Superior ovary, superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, woody (lignified) stone is derived from the Ovary (botany), ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a Berry (botany), different definition of ''berry''. Other fleshy fruits may have a stony enclosur ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovule
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the ''integument'', forming its outer layer, the ''nucellus'' (or remnant of the sporangium, megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center. The female gametophyte — specifically termed a ''megagametophyte'' — is also called the ''embryo sac'' in Flowering plant, angiosperms. The megagametophyte produces an ovum, egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. On the basis of the relative position of micropyle, body of the ovule, chalaza and funicle, there are six types of ovules. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The Ovary (plants), ovary of the gynoecium p ...

Stigma (botany)
The stigma (: stigmas or stigmata) is the receptive tip of a Gynoecium#Carpels, carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the Style (botany), style and ovary (botany), ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germination, germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals (Pollination syndrome#Biotic, ...

Carpel
Gynoecium (; ; : gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) '' pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stame ...
