Botany In A Day
''Botany in a Day: The Patterns Method of Plant Identification'' is a book by Thomas J. Elpel published by HOPS Press, LLC. The book emphasizes family characteristics for plant identification. Related plants typically have similar floral features and often similar uses. For example, plants of the mustard family (Brassicaceae) have four petals with six stamens (4 tall, 2 short), and most or all of the 3,200 species are considered edible. The book is used as a text at universities, high schools, and herbal schools across North America. It is also recommended as a resource for the Nature Merit Badge by the Boy Scouts of America Scouting America is the largest scouting organization and one of the largest List of youth organizations, youth organizations in the United States, with over 1 million youth, including nearly 200,000 female participants. Founded as the Boy Sco .... Although the text is primarily oriented towards North American plants, ''Botany in a Day'' has been used t ...

Nonfiction
Non-fiction (or nonfiction) is any document or media content that attempts, in good faith, to convey information only about the real world, rather than being grounded in imagination. Non-fiction typically aims to present topics objectively based on historical, scientific, and empirical information. However, some non-fiction ranges into more subjective territory, including sincerely held opinions on real-world topics. Often referring specifically to prose writing, non-fiction is one of the two fundamental approaches to story and storytelling, in contrast to narrative fiction, which is largely populated by imaginary characters and events. Non-fiction writers can show the reasons and consequences of events, they can compare, contrast, classify, categorise and summarise information, put the facts in a logical or chronological order, infer and reach conclusions about facts, etc. They can use graphic, structural and printed appearance features such as pictures, graphs or char ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Plant Identification
In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists. Modern tools include single or multi-access identification keys, which can be printed or computer-assisted. Overview The need to identify which plant is which has existed for time immemorial. The ability depends to a large extent on what criteria and whose system is used. Determination now relies on modern taxonomy to identify organisms. Taxonomy is the branch of biology which deals with identity, nomenclature and classification. The term was first coined in 1813 by Swiss botanist Augustin Pyramus de Candolle. Carl Linnaeus, who began modern taxonomy, used the term 'systematics' himself. Determination then requires comparisons of certain characteristics and then assigning a particul ...

Brassicaceae
Brassicaceae () or (the older but equally valid) Cruciferae () is a medium-sized and economically important Family (biology), family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in Rosette (botany), rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). , it was divided into two subfamilies, Brassicoideae and Aethionemoideae. The family contains the cruciferous vegetable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petals
Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually surrounded by an outer whorl of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as '' Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they inclu ...

Stamens
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in '' Canna iridiflora'' and '' Strelitzia nicolai''. The stamens in a flower are collectively called the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merit Badge (Boy Scouts Of America)
Merit badges are awards earned by members of Scouting America, based on activities within the area of study by completing a list of periodically updated requirements. The purpose of the merit badge program is to allow Scouts to examine subjects to determine if they would like to further pursue them as a career or vocation. The program also introduces Scouts to life skills such as contacting an adult they had not met before, arranging a meeting, and demonstrating their skills, similar to a job or college interview. The merit badge award is represented by a circular patch with an image representing the badge's topic. The patches for the Eagle-required merit badges are distinguishable by the silver border on the outside edge. Merit badges are displayed on a sash which can be worn with the Scouts BSA uniform on formal occasions. The National Council reviews and updates badges each year. There are currently 139 merit badges. Scouting organizations in other countries issue or ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boy Scouts Of America
Scouting America is the largest scouting organization and one of the largest List of youth organizations, youth organizations in the United States, with over 1 million youth, including nearly 200,000 female participants. Founded as the Boy Scouts of America in 1910, about 130 million Americans have participated in its programs, which are served by 465,000 adult volunteers. The organization became a founding member of the World Organization of the Scout Movement in 1922. The stated mission of Scouting America is to "prepare young people to make ethical and moral choices over their lifetimes by instilling in them the values of the Scout Oath and Law." Youth are trained in responsible citizenship, character development, and self-reliance through participation in a wide range of outdoor activities, educational programs, and, at older age levels, career-oriented programs in partnership with community organizations. For younger members, the Scout method is part of the program to inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the characte ...
