supports: Plectranthus, with some 350 species, is a genus of warm-climate plants occurring largely in the southern hemisphere, in sub-Saharan Africa, Madagascar, India and the Indonesian archipelago down to Australia and some Pacific Islands. They are closely related to "Solenostemon" and are known as the spurflowers. Several species are grown as ornamental plants, as leaf vegetables, as root vegetables for their edible tubers, or as medicine. The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World". The mediastinum (from Medieval Latin "mediastinus", "midway") is the central compartment of the thoracic cavity surrounded by loose connective tissue, as an undelineated region that contains a group of structures within the thorax. The mediastinum contains the heart and its vessels, the esophagus, trachea, phrenic and cardiac nerves, the thoracic duct, thymus and lymph nodes of the central chest. Bystropogon is a genus of evergreen shrubs in the Lamiaceae . It is native to the Canary Islands and Madeira in the western Atlantic Ocean . Allied to the Origanum and Thymus , the genus is characterized by tiny flowers in much - branched clusters , with plume - like sepals that elongate at the fruiting stage , giving the whole tip of each branch a fuzzy appearance . Stems are square in cross-section and leaves , arranged in opposite pairs , are aromatic when crushed . Cultivation The plant prefers mild and dry climates . Grow in very well - drained soil in sunny position . Propagate from seed or cuttings . Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land. In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a woody trunk and branches as a way to tower above other plants to compete for sunlight. In looser senses, the taller palms, the tree ferns, bananas and bamboos are also trees. Trees tend to be long-lived, some reaching several thousand years old. The tallest known tree, a coast redwood named Hyperion, stands high. Trees have been in existence for 370 million years. It is estimated that there are just over 3 trillion mature trees in the world. Salvia hispanica, commonly known as chia, is a species of flowering plant in the mint family, Lamiaceae, native to central and southern Mexico and Guatemala. The sixteenth-century "Codex Mendoza" provides evidence that it was cultivated by the Aztec in pre-Columbian times and economic historians say it may have been as important as maize as a food crop. It was given as an annual tribute by the people to the rulers in 21 of the 38 Aztec provincial states. Thymocytes are hematopoietic progenitor cells present in the thymus. Thymopoiesis is the process in the thymus by which thymocytes differentiate into mature T lymphocytes. The primary function of thymocytes is the generation of T lymphocytes (T cells). The thymus provides an inductive environment, which allows for the development and selection of physiologically useful T cells. The processes of beta-selection, positive selection, and negative selection shape the population of thymocytes into a peripheral pool of T cells that are able to respond to foreign pathogens and are immunologically tolerant towards self antigens. Plectranthus esculentus, with English common names kaffir potato, and Livingstone potato, is a species of plant in the dicot family Lamiaceae. It is indigenous to Africa, where it is grown for its edible tubers. It is more difficult to cultivate than "Plectranthus rotundifolius", but able to give greater yields. Although the crop is similar to a potato it is from the mint family but it is still quite nutritious and useful. This crop can benefit many subsistence farmers since it is native, easy to grow, growing popularity in the market and quite nutritious. Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people. Oregano (or , scientific name "Origanum vulgare", is a flowering plant in the mint family (Lamiaceae). It is native to temperate western and southwestern Eurasia and the Mediterranean region. Plectranthus edulis, the Ethiopian potato, known as "Welayta dinich" in Amharic, is a species of annual plant in the Lamiaceae family. It is indigenous to Ethiopia, where it is grown for its edible tubers. The tubers are cooked before they are eaten. Salvia is the largest genus of plants in the mint family, Lamiaceae, with nearly 1000 species of shrubs, herbaceous perennials, and annuals. Within the Lamiaceae, "Salvia" is part of the tribe Mentheae within the subfamily Nepetoideae. It is one of several genera commonly referred to as sage. Origanumis a genus of herbaceous perennials and subshrubs in the family Lamiaceae, native to Europe, North Africa, and much of temperate Asia, where they are found in open or mountainous habitats. A few species also naturalized in scattered locations in North America and other regions. The Canary Islands, also known as the Canaries, are an archipelago and autonomous community of Spain located on the Atlantic Ocean, west of Morocco. The Canaries are among the outermost regions (OMR) of the European Union proper. It is also one of the eight regions with special consideration of historical nationality recognized as such by the Spanish Government. Stachys is one of the largest genera in the flowering plant family Lamiaceae. Estimates of the number of species in the genus vary from about 300, to about 450. The type species for the genus is "Stachys sylvatica". "Stachys" is in the subfamily Lamioideae. Generic limits and relationships in this subfamily are poorly known. Teak (Tectona grandis) is a tropical hardwood tree species placed in the flowering plant family Lamiaceae. "Tectona grandis" is a large, deciduous tree that occurs in mixed hardwood forests. It has small, fragrant white flowers and large papery leaves that are often hairy on the lower surface. It is sometimes known as the "Burmese teak". Teak wood has a leather-like smell when it is freshly milled. It is particularly valued for its durability and water resistance, and is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects. "Tectona grandis" is native to south and southeast Asia, mainly India, Sri Lanka, Indonesia, Malaysia, Thailand, Myanmar and Bangladesh but is naturalised and cultivated in many countries in Africa and the Caribbean. Myanmar's teak forests account for nearly half of the world's naturally occurring teak.
  Molecular studies show that there are two centres of genetic origin of teak; one in India and the other in Myanmar and Laos. "CP teak" ("Central Province" teak) is a description of teak from the central states of India. "Nagpur teak" is another regional Indian teak. It produces small, white flowers arranged in dense clusters (panicles) at the end of the branches. Flowers contain both types of reproductive organs (perfect flowers) Perilla is of the mint family, Lamiaceae. Though known to several cultures by different names, the disparate varieties are now classified under the single species "Perilla frutescens". The plant overall resembles the stinging nettle, though the leaves are somewhat rounder. A subshrub (Latin "suffrutex") or dwarf shrub is a short woody plant. Prostrate shrub is a related term. "Subshrub" is often used interchangeably with "bush". A flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds. The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c. 295,383 known species. Like gymnosperms, angiosperms are seed-producing plants; they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the Greek composite word ("angeion", "case" or "casing", and "sperma", "seed") meaning "enclosed seeds", after the enclosed condition of the seeds. In general use, herbs are any plants used for food, flavoring, medicine, or fragrances for their savory or aromatic properties. Culinary use typically distinguishes herbs from spices. "Herbs" refer to the leafy green or flowering parts of a plant (either fresh or dried), while "spices" are produced from other parts of the plant (usually dried), including seeds, berries, bark, roots and fruits. Marjoram ("Origanum majorana", syn. "Majorana hortensis" Moench, "Majorana majorana" (L.) H. Karst) is a somewhat cold-sensitive perennial herb or undershrub with sweet pine and citrus flavors. In some Middle Eastern countries, marjoram is synonymous with oregano, and there the names sweet marjoram and knotted marjoram are used to distinguish it from other plants of the genus "Origanum". It is also called pot marjoram, although this name is also used for other cultivated species of "Origanum". Plectranthus rotundifolius or Solenostemon rotundifolius, commonly known as "native" or "country potato" in Africa and called "Chinese potato" in India is a perennial herbaceous plant of the mint family (Lamiaceae) native to tropical Africa. It is cultivated for its edible tubers primarily in West Africa, as well as more recently in parts of Asia, especially India, Sri Lanka, Malaysia, and Indonesia. A shrub or bush is a small to medium-sized woody plant. It is distinguished from a tree by its multiple stems and shorter height, usually under 6 m (20 ft) tall. Plants of many species may grow either into shrubs or trees, depending on their growing conditions. Small, low shrubs, generally less than 2 m (6.6 ft) tall, such as lavender, periwinkle and most small garden varieties of roses, are often termed subshrubs. A T cell, or T lymphocyte, is a type of lymphocyte (a subtype of white blood cell) that plays a central role in cell-mediated immunity. T cells can be distinguished from other lymphocytes, such as B cells and natural killer cells, by the presence of a T-cell receptor on the cell surface. They are called "T cells" because they mature in the thymus from thymocytes (although some also mature in the tonsils). The several subsets of T cells each have a distinct function. The majority of human T cells rearrange their alpha and beta chains on the cell receptor and are termed alpha beta T cells ( T cells) and are part of the adaptive immune system. Specialized gamma delta T cells, (a small minority of T cells in the human body, more frequent in ruminants), have invariant T cell receptors with limited diversity, that can effectively present antigens to other T cells and are considered to be part of the innate immune system. Thyme is an evergreen herb with culinary, medicinal, and ornamental uses. 
  The most common variety is "Thymus vulgaris". Thyme is of the genus "Thymus" of the mint family (Lamiaceae), and a relative of the oregano genus "Origanum". Stachys affinis, commonly called crosne, Chinese artichoke, Japanese artichoke, knotroot, and artichoke betony, is a perennial herbaceous plant of the family Lamiaceae, originating from China. Its rhizome can be grown and eaten as a root vegetable. The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. A vine (Latin "vnea" "grapevine", "vineyard", from "vnum" "wine") in the narrowest sense is the grapevine ("Vitis"), but more generally it can refer to any plant with a growth habit of trailing or (that is, climbing) stems or runners. The word also can refer to such stems or runners themselves, for instance when used in wicker work. The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells or T lymphocytes mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders. The thymus is composed of two identical lobes and is located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum. Histologically, each lobe of the thymus can be divided into a central medulla and a peripheral cortex which is surrounded by an outer capsule. The cortex and medulla play different roles in the development of T-cells. Cells in the thymus can be divided into thymic stromal cells and cells of hematopoietic origin (derived from bone marrow resident hematopoietic stem cells). Developing T-cells are referred to as thymocytes and are of hematopoietic origin. Stromal cells include epithelial cells of the thymic cortex and medulla, and dendritic cells. Lamiaceae (or )
  or Labiatae is a family of flowering plants commonly known as the mint or deadnettle family. Many of the plants are aromatic in all parts and include widely used culinary herbs, such as basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla. Some species are shrubs, trees (such as teak), or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage, such as "Coleus". Others are grown for seed, such as "Salvia hispanica" (chia), or for their edible tubers, such as "Plectranthus edulis", "Plectranthus esculentus", "Plectranthus rotundifolius", and "Stachys affinis" (Chinese artichoke).
