Orto Botanico Dell'Università Di Siena
The Orto Botanico dell'Università di Siena (2.5 hectares) is a botanical garden operated by the University of Siena. It is located at Via P. A. Mattioli, 4, Siena, Tuscany, Italy, and open daily. The garden's history reaches back to 1588 when the university began to raise medicinal herbs. In 1756 the field of herbal studies was supplanted by natural history, and starting in 1759, under the direction of Giuseppe Baldassarri, the garden began to collect uncommon plants. In 1784 the Grand Duke of Tuscany Peter Leopold began a university reform, and in a short time the garden's collection grew to contain more than a thousand new plants, many from abroad. Its first published record ('the Seminum Index Siena') listed some 900 species, including several hundred from outside Italy. In 1856, the garden moved to its present location, the botany institute was constructed in 1910–1912, and in the 1960s the garden's area was doubled. Today the garden is located inside Siena's city wall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siena
Siena ( , ; lat, Sena Iulia) is a city in Tuscany, Italy. It is the capital of the province of Siena.

Siena is also home to the oldest bank in the world, the Monte dei Paschi bank, which has been operating continuously since 1472. Several significant Renaissance painters worked and were born in Siena, among them Duccio, Ambrogio Lorenzetti, Simone Martini and Sassetta, and influenced the course of Italian and European art. The University of Siena, originally called ''Studium Senese'', was founded in 1240, making it one of the oldest universities in continuous operation in the world.

Succulent
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as '' Glottiphyllum semicyllindricum'' and '' Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to s ...

Botanical Gardens In Italy
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", "herbs" "grass", or "fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, medici ...

Thymus Acicularis
The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, thymus cell lymphocytes or ''T cells'' mature. T cells are critical to the adaptive immune system, where the body adapts to specific foreign invaders. The thymus is located in the upper front part of the chest, in the anterior superior mediastinum, behind the sternum, and in front of the heart. It is made up of two lobes, each consisting of a central medulla and an outer cortex, surrounded by a capsule. The thymus is made up of immature T cells called thymocytes, as well as lining cells called epithelial cells which help the thymocytes develop. T cells that successfully develop react appropriately with MHC immune receptors of the body (called ''positive selection'') and not against proteins of the body (called ''negative selection''). The thymus is largest and most active during the neonatal and pre-adolescent periods. By the early teens, the thymus begins to decrease in size and act ...
