Prunus Ursina
''Prunus ursina'' (bear's plum, ) is a species of ''prunus'' native to the woods of Western Asia from Turkey to Syria, Israel and Lebanon. Some sources include this species in '' Prunus cocomilia''. Etymology ''Prunus'', from the Latin "prūnus" which is a loan from Greek (προῦνον, prounon) means plum tree. ''Ursina'' derives from "ursus", a bear, referring to one of a bear's favorite foods. Description ''Prunus ursina'' is a deciduous shrub to a small tree, reaching 4 to 8 meters in height; it is highly branched and the branches sometimes bear spines. The twigs are velvety and the leaves are ovate to oblong. ''Prunus ursina'' produces white hermaphrodite flowers in pairs during the spring. Its 2-to-3 cm unpalatable fruit is globose and turns yellow to dark orange when ripe but may be toxic if consumed excessively. Uses The fuit can be used to obtain a dark grey to green dye and a green dye can be obtained from the leaves. Plants in the ''Prunus'' species contain ...

Leaf Shape
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Lebanon And Syria
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Sect
''Prunus'' is a genus of trees and shrubs, which includes (among many others) the fruits plums, cherries, peaches, nectarines, apricots, and almonds. Native to the North American temperate regions, the neotropics of South America, and the paleotropics of Asia and Africa, 430 different species are classified under ''Prunus''. Many members of the genus are widely cultivated for their fruit and for decorative purposes. ''Prunus'' fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel") which is edible in many species (such as almonds) but poisonous in others (such as apricots). Besides being eaten off the hand, most ''Prunus'' fruit are also commonly used in processing, such as jam production, canning, drying, and seeds for roasting. Botany Members of the genus can be deciduous or evergreen. A few species ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honey Fungus
''Armillaria'' is a genus of fungi that includes the '' A. mellea'' species known as honey fungi that live on trees and woody shrubs. It includes about 10 species formerly categorized summarily as ''A. mellea''. ''Armillarias'' are long-lived and form the largest living fungi in the world. The largest known organism (of the species ''Armillaria ostoyae'') covers more than in Oregon's Malheur National Forest and is estimated to be 2,500 years old. Some species of ''Armillaria'' display bioluminescence, resulting in foxfire. ''Armillaria'' can be a destructive forest pathogen. It causes "white rot" root disease (see Plant pathology section) of forests, which distinguishes it from ''Tricholoma'', a mycorrhizal (non-parasitic) genus. Because ''Armillaria'' is a facultative saprophyte, it also feeds on dead plant material, allowing it to kill its host, unlike parasites that must moderate their growth to avoid host death.

Hydrogen Cyanide
Hydrogen cyanide, sometimes called prussic acid, is a chemical compound with the formula HCN and structure . It is a colorless, extremely poisonous, and flammable liquid that boils slightly above room temperature, at . HCN is produced on an industrial scale and is a highly valued precursor to many chemical compounds ranging from polymers to pharmaceuticals. Large-scale applications are for the production of potassium cyanide and adiponitrile, used in mining and plastics, respectively. It is more toxic than solid cyanide compounds due to its volatile nature. Structure and general properties Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide. Hydrogen cyanide is weakly acidic with a p''K''a of 9.2. It partially ionizes in water solution to give the cyanide anion, CN−. A solution of hydrogen cyanide in water, represented as HCN, is called ''hydrocyanic acid''. The salts of the cyanide ani ...

Prunasin
(''R'')-prunasin is a cyanogenic glycoside related to amygdalin. Chemically, it is the glucoside of (''R'')-mandelonitrile. Natural occurrences Prunasin is found in species in the genus ''Prunus'' such as ''Prunus japonica'' or '' P. maximowiczii'' and in bitter almonds. It is also found in leaves and stems of '' Olinia ventosa'', '' O. radiata'', '' O. emarginata'' and '' O. rochetiana'' and in ''Acacia greggii''. It is a biosynthetic precursor of and intermediate in the biosynthesis of amygdalin, the chemical compound responsible for the taste of bitter almond. It is also found in dandelion coffee, a coffee substitute. Sambunigrin Sambunigrin, a diastereomer of prunasin derived from (''S'')-mandelonitrile instead of it the (''R'')-isomer, has been isolated from leaves of the elder tree (''Sambucus nigra''). Sambunigrin is present in the leaves and stems of elder at a 1:3 ratio of sambunigrin to prunasin, and 2:5 in the immature seed. It is not found in the root. Biosynthe ...

Amygdalin
Amygdalin (from Ancient Greek: ' "almond") is a naturally occurring chemical compound found in many plants, most notably in the seeds (kernels) of apricots, bitter almonds, apples, peaches, cherries, and plums. Amygdalin is classified as a cyanogenic glycoside because each amygdalin molecule includes a nitrile group, which can be released as the toxic cyanide anion by the action of a beta-glucosidase. Eating amygdalin will cause it to release cyanide in the human body, and may lead to cyanide poisoning. Since the early 1950s, both amygdalin and a chemical derivative named ''laetrile'' have been promoted as alternative cancer treatments, often under the misnomer vitamin B17 (neither amygdalin nor laetrile is a vitamin). Scientific study has found them to not only be clinically ineffective in treating cancer, but also potentially toxic or lethal when taken by mouth due to cyanide poisoning. The promotion of laetrile to treat cancer has been described in the medical literature a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Israel (region)
The Land of Israel () is the traditional Jewish name for an area of the Southern Levant. Related biblical, religious and historical English terms include the Land of Canaan, the Promised Land, the Holy Land, and Palestine (see also Israel (other)). The definitions of the limits of this territory vary between passages in the Hebrew Bible, with specific mentions in Genesis 15, Exodus 23, Numbers 34 and Ezekiel 47. Nine times elsewhere in the Bible, the settled land is referred as "from Dan to Beersheba", and three times it is referred as "from the entrance of Hamath unto the brook of Egypt" (1 Kings 8:65, 1 Chronicles 13:5 and 2 Chronicles 7:8). These biblical limits for the land differ from the borders of established historical Israelite and later Jewish kingdoms, including the United Kingdom of Israel, the two kingdoms of Israel (Samaria) and Judah, the Hasmonean Kingdom, and the Herodian kingdom. At their heights, these realms ruled lands with similar but not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
