subject: Thorns In The Culture [print this page] Among the grasses ( Poaceae ) and sedges ( Cyperaceae ), the inflorescence is a small elementary spike formed by one or more sessile flowers or sitting on an articulated rachis, often brief, called rachilla and protected by bracts called sterile glumes . Inflorescence such called herringbone . The flowers may be hermaphrodite or unisexual and have a perianth rudimentary 2 or 3 pieces, or glumelulas ldculas. These lodculas are turgid be determined at the opening of the flower box anthecium or during flowering, allowing setting out the feathery stigmas and stamens. The florets are formed by the lemma, attached to the rachilla, and palea inserted on the floral axis that is born on the rachilla in the axil of the lemma and supports the floral organs themselves. The lemma (or lower glumella) is shaped keel can be mutica or bristle-pointed, and embraces the paddle with its edges. The edge comes at the end of the lemma or on its back. The upper palea lanceolate or glumella, binervada and a cover enclosing the flower. Glumes are inserted on the rachilla one below the other.
The blade is usually used as a symbol of abundance, or worship of the goddess Ceres because she, according to mythology, the inventor of the mode of planting and harvesting wheat and grains, which had to Triptolemus per student. The former are examples of medals, which sees a single spike, as in those of Artaclia, Bailo, Butroto, Camaloduno, Gades T Hipa, Ituci, Lelia, Metaponte, Panormo, Segbriga and translated, in a family Licinia, in Sicilian Pirro and Egyptian Augustus and Nero . The same means a crown of spikes, offering medals Entella, Eresos, Nisa in Syria and Syracuse and other family and Musidia Jimia and Lysimachus , king of Thrace .
For the same reason is the symbol pin several provinces and cities abundant crops, such as Africa , Antioch in Syria, Alalia, Carras, Caesarea in Palestine , Cyzicus, Edessa in Mesopotamia , Spain, Philippopolis in Thrace , Germanicia, Italy , Nesibis , Nicaea , Nicomedia, Ptolemais, Outline, Sarnosata, Sicily , Side, Silius, Singara, Tarsus, Tiana Tavio and medals which usually shows a woman crowned with towers and seated on rocks with spikes in D. meaning the genius of the city and producing many crops.
The spines are formations acute aleznadas, sometimes branched, provided with vascular tissue, very rich in supporting tissues and, therefore, rigid. The spines may have originated as a transformation of the stem , ie, which are branches reduced, as in Prunus spinosa and Gleditsia triacanthos , and are called cauline spines . In this case, the vascular tissue of the spine is a continuation of the stem wood. Hydrolea spinosa , typical marsh wetland plant, is illustrative of spina Stem, as their spines are sometimes tiny leaves, like a stalk . The spikes can also be the result of the transformation of a sheet , as in the case of the cactus and species of the genus Berberis , and are called leaf spines . Finally, in rare cases, the bones may be the result of the modification of the root through an intense process of lignification and are called radical thorns . Several terms commonly used in botany derived from the word spine. So "thorny / a" refers to a tissue, organ or a plant that has thorns "spinulose / a" or "espinescente" when showing the spines are small. 2
The presence of spines is a character that is particularly widespread in plants typical of arid regions such as deserts , steppes , dry forests and thorny. In these cases the spines are generally the result of processing sheets and allow to reduce perspiration from the plant and assist the water economy because they have no stomas . In other climatic regions in plants and xerophytes are also thorns as these structures with hard and sharp pointed tips, some with awl-shaped tips, hook or hooks are an excellent defense against animal herbivores .
In Botany is called sting or Aculco to the spike that comes from the epidermal tissue of some plants. 2 Unlike the thorns, the stings have no vascular tissue, so they are easier to start. The typical example is the thorn rose , also, the stings of Ceiba speciosa , the club drunk , and Fagara rhoifolia are emergencies formed by cortical stem tissue.
It is known that primitive man used bones as tools. Human history records a variety of cultural references to these acute plant defense mechanisms.
The Book of Genesis account of creation of the bones as one of the punishments meted out to Adam and Eve for their sin. One of the most enduring cultural images is the crown of thorns, according to the Bible , was placed on the head of Jesus before his crucifixion.
A popular myth in which a bone is also involved is that of Androcles , a runaway slave of ancient Greece who is aware that befriended a lion to extract a thorn from the paw.
