Streptosolen
''Streptosolen'' is a monotypic genus of flowering plants in the family Solanaceae. It is closely related to the genus Browallia, within which it was originally placed. The single species, ''Streptosolen jamesonii'', the marmalade bush or fire bush, is an evergreen shrub bearing loose clusters of flowers which change gradually from yellow to red as they develop, resulting in an overall appearance resembling orange marmalade (whence the name), found in open woodlands in Colombia, Venezuela, Ecuador, and Peru. In its native Ecuador, the plant has the Spanish common names flor de quinde (= 'hummingbird flower'), flor del sol (= 'flower of the sun') and jaboncillo (= 'little soap (plant)').Montserrat Rios, Fani Tinitana, Pablo Jarrín, Natalia Donoso and Juan Carlos Romero-Benavides, ''“Horchata” drink in Southern Ecuador : medicinal plants and people’s wellbeing'' Journal of Ethnobiology and Ethnomedicine (2017).

Solanaceae
The Solanaceae , or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida ( dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology. The name Solanaceae derives from the genus ''Solanum''. The etymology of the Latin word is unclear. The name may come from a perceived resemblance of certain solanaceous flowers to the sun and its rays. At least one species of ''Solanum'' is known as the "sunberry". Alternatively, the name could originate from the Latin verb ''sol ...

John Miers (botanist)
John Miers, FRS FLS (25 August 1789 – 17 October 1879. Kensington), knight grand cross of the Order of the Rose, was a British botanist and engineer, best known for his work on the flora of Chile and Argentina. Miers was born in London to a jeweller from Yorkshire, and showed interest in mineralogy and chemistry from an early age. His first published work was a monograph on nitrogen which appeared in the ''Annals of Philosophy'' in 1814. After his marriage in 1818 he travelled to South America to participate in a venture to exploit the mineral resource of Chile, particularly copper. However, after landing in Buenos Aires his wife came down with childbed fever on the trip across country, and he decided not to continue to Chile, instead starting a study of the local flora, which at that time was largely unresearched. In May 1819 Miers arrived in Santiago, Chile, having arranged the clandestine transport of coin presses, and settled at Concón, near Valparaíso. He developed bu ...

Glossary Of Leaf Morphology
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] |
Armando Theodoro Hunziker
Armando Theodoro Hunziker (August 29, 1919 in Chacabuco, Argentina – December 12, 2001 in Córdoba, Argentina) was an Argentine botanist. He had specialized in the study of systems biology of the family Solanaceae, having contributed with a large number of investigations and publications. Biography He was born to a Swiss Argentine family. An aunt taught him German, French, Italian and English. He studied Agronomy at the University of Buenos Aires, where he met his mentor, Prof. Lorenzo R. Parodi, who supervised his graduate thesis about the genus ''Cuscuta'', a parasite that affects wild and cultivated plants in Argentina and Uruguay. At the age of 22, he received the first prize for his work ("Premio José Manuel de Altoaguirre") and one year later he received another prize ("Premio Eduardo Holmberg"). In 1945, at the age of 25, he was nominated curator of the Botanical Museum of the National University of Córdoba, recommended by the Nobel Prize winner in Medicine ...

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...

Trichomes
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stoma
In botany, a stoma (from Greek ''στόμα'', "mouth", plural "stomata"), also called a stomate (plural "stomates"), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening. The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture. Air, containing oxygen, which is used in respiration, and carbon dioxide, which is used in photosynthesis, passes through stomata by gaseous diffusion. Water vapour diffuses through the stomata into the atmosphere in a process called transpiration. Stomata are present in the sporophyte generation of all land plant groups except liverworts. In vascular plants the number, size and distribution of stomata varies widely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...
