Ruellia Simplex
''Ruellia simplex'', the Mexican petunia, Mexican bluebell or Britton's wild petunia, is a species of flowering plant in the family Acanthaceae. It is a native of Mexico, the Caribbean, and South America. It has become a widespread invasive plant in Florida, where it was likely introduced as an ornamental before 1933, as well as in the eastern Mediterranean, South Asia and other parts of the eastern hemisphere. Taxonomy and synonyms ''Ruellia simplex'' C.Wright is the oldest and accepted name for this species, which has been variously called ''Ruellia angustifolia'' (Nees) Lindau, ''Ruellia brittoniana'' Leonard, and ''Cryphiacanthus angustifolius'' Nees, among several synonyms. The genus is named after French botanist Jean Ruel, while the specific name refers to the simple, not compound leaves. Description ''Ruellia simplex'' is an evergreen perennial growing tall, forming colonies of stalks with lance-shaped leaves that are and wide. Trumpet shaped flowers are metallic blue ...

Charles Wright (botanist)
Charles Wright (October 29, 1811 – August 11, 1885) was an American botanist. History Wright was born in Wethersfield, Connecticut,Mary Gunn and L. E. W. Codd the son of James Wright and Mary née Goodrich. He studied classics and mathematics at Yale, and in October 1835 moved to Natchez, Mississippi to tutor a plantation owner's family. His employer's business failed two years later, and he moved to Texas, working as a land surveyor and teacher. He surveyed ground for the Southern Pacific Transportation Company, Pacific Railroad Company.Bo Beolens, Michael Watkins and Michael Grayson During this time, he also collected plants for Asa Gray. Gray thought of Wright as one of his most trusted collectors.Carolyn Dodson In 1849, he joined an army expedition (with Gray's help) through Texas, botanising from Galveston to San Antonio and then on to El Paso, Texas, El Paso. But he had to walk most of the 673 miles, (which took over 104 days effort).Dan Lewis Fische He collected seeds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthaceae
Acanthaceae is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. Representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests. Description Plants in this family have simple, opposite, decussated leaves with entire (or sometimes toothed, lobed, or spiny) margins, and without stipules. The leaves may contain cystoliths, calcium carbonate concretions, seen as streaks on the surface. The flowers are perfect, zygomorphic to nearly actinomorphic, and arranged in an inflorescence that is either a spike, raceme, or cyme. Typically, a colorful bract subtends ea ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Ruel
Jean Ruel (1474 – 24 September 1537), also known as Jean Ruelle or Ioannes Ruellius in its Latinised form, was a French physician and botanist noted for the 1536 publication in Paris of ''De Natura Stirpium'', a Renaissance treatise on botany. Ruel was born in Soissons. He was self-taught in Greek and Latin, and studied medicine, graduating in 1508, or, according to other sources in 1502. In 1509 he became physician to Francis I, devoted himself at the same time to a study of botany and pharmacology. He was a professor at the University of Paris, and a large part of his academic career was given to an analysis of Dioscorides''De Materia Medica'' of which he published a Latin translation in 1516. Ruel's three-volume ''De Natura Stirpium'', which was published without illustrations, was intended partly as a gloss to the ancient writers. In it he described in great detail not only the habit and habitat, but also the smell and taste of each plant, producing a list in French of a la ...

Escaped Plant
Escaped plants are cultivated plants, usually garden plants, that are not originally native to an area, and due to their dispersal strategies, have escaped from cultivation and have settled in the wild and bred there, whether intentionally or unintentionally. Escaped plants are purposefully introduced plants that have naturalized in the wild and can develop into invasive plants, the settlement of which is to be assessed as problematic. Other commonly used terms include escaped garden plant, garden escapee, escaped ornamental or garden refugee. Some plants are valued as ornamental plants since they are very adaptable and easy to grow, and therefore would escape cultivation and become weedy in various ecosystems with far-reaching ecological and economic consequences. They can also develop into invasive intruders, especially in fragile or unstable ecosystems. Occasionally, their spread can even be traced back to botanical gardens. Therefore, escaped plants are the subject of rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
