Hippeastrum is a genus of about 90 species, and over 600 hybrids and cultivars, of perennial, herbaceous and bulbous plants, native to tropical and subtropical regions of the Americas, from Mexico south to Argentina and on some islands in the Caribbean. The majority have large, fleshy bulbs—usually about the size of a softball—and tall, broad, strap-like leaves that are (generally) evergreen, and large red or purple flowers. Numerous colors and cultivars have been created over the past hundred years.
Acorus is a genus of monocot flowering plants. This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots. Some older studies indicated that it was placed in a lineage, that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots. However, modern phylogenetic studies demonstrate that Acorus is sister to all other monocots. Common names include calamus and sweet flag.
Jan Frederik Gronovius was a Dutch botanist notable as a patron of Linnaeus.
Mark Catesby was an English naturalist who studied the flora and fauna of the New World. Between 1729 and 1747, Catesby published his Natural History of Carolina, Florida and the Bahama Islands, the first published account of the flora and fauna of North America. It included 220 plates of birds, reptiles, amphibians, fish, insects, mammals and plants.
In biology, a type is a particular specimen of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage, a type was a taxon rather than a specimen.
Phragmipedium kovachii is an orchid species found to be new to science in 2001, native to the Andean cloud forests of northern Peru. A species with terrestrial habit and growing in clumps of several individuals, it displays showy pink to purple flowers up to 20 cm (8 in) wide. It is currently considered a critically endangered species by the IUCN, due to overcollection in the wild.
Linnaea borealis is a species of flowering plant in the family Caprifoliaceae. It is the only species in the genus Linnaea. It is a boreal to subarctic woodland subshrub, commonly known as twinflower.
Claytonia is a genus of flowering plants native to Asia, North America, and Central America. The vitamin-rich leaves can be eaten raw or cooked, and the tubers can be prepared like potatoes.
Jane Colden was an American botanist, described as the "first botanist of her sex in her country" by Asa Gray in 1843. Although not acknowledged in contemporary botanical publications, she wrote a number of letters resulting in botanist John Ellis writing to Carl Linnaeus of her work applying the Linnaean system of plant identification to American flora, for which botanist Peter Collinson stated "she deserves to be celebrated". Contemporary scholarship maintains that she was the first female botanist working in America, which ignores, among others, Maria Sibylla Merian or Catherine Jérémie. Colden was respected as a botanist by many prominent botanists including John Bartram, Peter Collinson, Alexander Garden, and Carl Linnaeus. Colden is most famous for her untitled manuscript, housed in the British Museum, in which she describes the flora of the Hudson Valley in the Newburgh region of New York state, including ink drawings of 340 different species.
Soyauxia is a genus of flowering plants in the family Peridiscaceae. They are small trees or erect shrubs from wet forests of tropical West Africa. Eight specific names have been published in Soyauxia. Additional species have been discovered, but their names and descriptions will not be published until 2009 or 2010. The type species for the genus is Soyauxia gabonensis.
Senecio madagascariensis, also known as Madagascar ragwort, is a species of the genus Senecio and family Asteraceae that is native to Southern Africa. Other common names include Madagascar groundsel and fireweed. It has been included on the noxious weeds list for Hawaii and the reject list for Australia. S.madagascariensis is the diploid cytotype of S.inaequidens.
Asplenium trichomanes, the maidenhair spleenwort, is a small fern in the spleenwort genus Asplenium. It is a widespread and common species, occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies.
John Clayton (1694/5–1773) was an Anglican minister in and for decades clerk for Gloucester County in the Colony of Virginia who is today best known as a plant collector and botanist. He may be confused with several distant family members, including Rev. John Clayton who served as minister at Jamestown (1682–1684) and conducted various scientific experiments, before returning to England.
Stylidium affine is a species in the genus Stylidium that is endemic to Western Australia.
Adiantum pedatum, the northern maidenhair fern or five-fingered fern, is a species of fern in the family Pteridaceae, native to moist forests in eastern North America. Like other ferns in the genus, the name maidenhair refers to the slender, shining black stipes.
Torminalis is a genus of plants in the rose family Rosaceae. The genus Torminalis was formerly included within the genus Sorbus, as the section Torminaria, but the simple-leafed species traditionally classified in Sorbus are now considered to form a separate monophyletic group. It is monotypic, being represented by the single species, Torminalis glaberrima, commonly known as wild service tree, chequers, and checker tree. This tree is native to Europe, parts of northern Africa and western Asia.
Iris aphylla is a species in the genus Iris, it is also in the subgenus Iris, and in the section Iris. It is a rhizomatous perennial, from Asia to Europe. It is found in Azerbaijan, Russian Federation, Czech Republic, Germany, Hungary, Poland, Belarus, Ukraine, Bulgaria, Albania, Former Yugoslavia, Italy, Romania and France. It has dark green or bright green, sword-shaped, long grass-like leaves, that die/fade away in the winter. It also has a slender stem, with several branches and green and purplish spathes. It has 3–5 large flowers, in shades of bright purple, purple, violet, dark blue, blue-violet and dark violet, which bloom between spring and early summer. Occasionally, they re-bloom in the autumn, before the seed capsule is formed. It is cultivated as an ornamental plant in temperate regions. There is one known subspecies Iris aphylla subsp. hungarica Hegi.
Iris aphylla subsp. hungarica is a plant subspecies in the genus Iris, it is also in the subgenus Iris. It is a subspecies of Iris aphylla. It is a rhizomatous perennial, from the Carpathian Mountains and Pannonian Basin. Found within the countries of Romania, Hungary, Slovakia, Ukraine, Moldova, and Italy. It has curved, pointed, thin leaves, slender stem, several large flowers in shades of purple, or dark purple, or violet-blue. It is a rare plant, that is protected by environmental law in the various countries of Europe.
Iris benacensis is a plant species in the genus Iris, it is also in the subgenus Iris. It is a rhizomatous perennial, from Italy. It has similar sized leaves and stem, and blue-purple shaded flowers, that have a white, blue and yellow beard. It was once classified as a synonym of Iris aphylla, before being re-classified as a species in its own right, although some sources still call it a synonym. It is cultivated as an ornamental plant in temperate regions.
Iris perrieri is a plant species in the genus Iris; it is also in the subgenus Iris. It is a rhizomatous perennial, from the Savoy Alps in southern France and recently in Italy. It has green, deeply ribbed, sickle shaped leaves, a slender stem with a branch, 1–3 scented flowers that are violet or purple, with a white or pale blue beard. It is rarely cultivated as an ornamental plant in temperate regions, due to its rarity in the wild. It was once thought to be a form of Iris aphylla, before cell (chromosome) analysis determined it to be a separate species.
