Jordan Pond
Jordan Pond is an oligotrophic tarn in Acadia National Park near the town of Bar Harbor, Maine. The pond covers to a maximum depth of with a shoreline of . The pond was formed by the Wisconsin Ice Sheet during the last glacial period. Penobscot Mountain (1194 ft) rises to the west, while Pemetic Mountain (1247 ft) rises to the east. Two roche moutonnées known as The Bubbles (North and South) rise above the northeastern shoreline. The southern end is constrained by glacial debris and an artificial dam. The pond has clear water, with visibility normally and occasionally recorded up to , the deepest recordings in Maine. The pond exhibits high levels of dissolved oxygen, and low levels of plant nutrients and plant life. Some types of boating are permitted, but people and pets are prohibited from entering the water as it is the water supply for the village of Seal Harbor. Park usage Park officials estimate that roughly 60 percent of park visitors will visit the pond, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jordan Pond House
Jordan Pond House is a restaurant in Seal Harbor, Maine. It is situated at the southwestern corner of the Park Loop Road, overlooking Jordan Pond from its southern shore. Two rôche moutonnées, known as "The Bubbles", provide the backdrop to the view from the house's lawn at the rear of the 60-acre property. The property's history can be traced to 1847, when the first settlers set up a logging operation. The original farm house was constructed by the Jordan family, locals for whom the pond and house were named. Jordan Pond House was established as a restaurant by Melvan Tibbetts in the early 1870s. In 1883, Bostonian Charles T. How, one of the first to develop real estate in Bar Harbor, bought the property. In 1895, Mr and Mrs Thomas McIntyre took over the business, which would remain in their hands for the next half-century. Near the end of this reign, John D. Rockefeller Jr. purchased the property and donated it to the National Park Service to ensure its continued existence. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juncus
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plants that superficially resemble grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the most widespread and familiar species, the leaves are reduced t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potamogeton
''Potamogeton'' is a genus of aquatic, mostly freshwater, plants of the family Potamogetonaceae. Most are known by the common name pondweed, although many unrelated plants may be called pondweed, such as Canadian pondweed (''Elodea canadensis''). The genus name means "river neighbor", originating from the Greek ''potamos'' (river) and ''geiton'' (neighbor). Morphology ''Potamogeton'' species range from large (stems of 6 m or more) to very small (less than 10 cm). Height is strongly influenced by environmental conditions, particularly water depth. All species are technically perennial, but some species disintegrate in autumn to a large number of asexually produced resting buds called turions, which serve both as a means of overwintering and dispersal. Turions may be borne on the rhizome, on the stem, or on stolons from the rhizome. Most species, however, persist by perennial creeping rhizomes. In some cases the turions are the only means to differentiate species. The leav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isoetes Lacustris
''Isoetes lacustris'', the lake quillwort or Merlin's grass, is a boreal quillwort native on both sides of the northern Atlantic Ocean. Synonyms include ''Isoetes hieroglyphica''. Description The lake quillwort has many long, narrow leaves from 8–20 cm long and 0.5–2 mm broad, widening to 5 mm broad at the base. There is a sac that produces the spores at the bottom of each leaf base. The plant has a very short stem, called a corm, where all the leaves and roots are attached close together. It does not have traditional roots, but instead some of its leaves are modified to act like roots. These pseudo-roots are called rhizomorphs, and are attached to the bottom end of corm. The upper leaves are green and found sprouting in a clump. Reproduction usually takes place during the late summer or early fall. The sacs at the bottom of leaves create two types of spores, female (megaspores, about 0.5 mm diameter) and male (microspores, a few micrometres in diamete ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Merritt Lyndon Fernald
Merritt Lyndon Fernald (October 5, 1873 – September 22, 1950) was an American botanist. He was a respected scholar of the taxonomy and phytogeography of the vascular plant flora of temperate eastern North America. During his career, Fernald published more than 850 scientific papers and wrote and edited the seventh and eighth editions of ''Gray's Manual of Botany''. Fernald coauthored the book ''Edible Wild Plants of Eastern North America'' in 1919–1920 with Alfred Kinsey, which was published in 1943. Biography Fernald was born in Orono, Maine. His parents were Mary Lovejoy Heywood and Merritt Caldwell Fernald, a college professor at the University of Maine. Fernald attended Orono High School, during which time he decided that he wanted to become a botanist. He collected plants around Orono and published two botanical papers while still attending high school.

Alvah Augustus Eaton
Alvah Augustus Eaton (November 20, 1865 – September 29, 1908) was an American botanist who described many species of pteridophytes, orchids and grass. Early life Eaton was born in Seabrook, New Hampshire, and moved to a family farm in Salisbury, Massachusetts when he was twelve. He finished a four-year high school education within two years at Putnam School in Newburyport. Career He worked as a teacher for a year in Seabrook, and for three more in California, along with farming. After returning to New England, he decided to become a florist due to pressure from poor health. He went on three field trips to Florida and one to Europe for the Ames Botanical Laboratory in Easton, Massachusetts. He was a member of the Linnean Fern Chapter, precursor to the American Fern Society. He frequently contributed to the ''Fern Bulletin'' and developed an Herbarium for the Society.

Quillwort
''Isoetes'', commonly known as the quillworts, is the only extant genus of plants in the family Isoetaceae, which is in the class of lycopods. There are currently 192 recognized species, with a cosmopolitan distribution but with the individual species often scarce to rare. Some botanists split the genus, separating two South American species into the genus ''Stylites'', although molecular data place these species among other species of ''Isoetes'', so that ''Stylites'' does not warrant taxonomic recognition. Species of ''Isoetes'' virtually identical to modern forms have existed since the Jurassic epoch. The name of the genus may also be spelled ''Isoëtes''. The diaeresis (two dots over the e) indicates that the o and the e are to be pronounced in two distinct syllables. Including this in print is optional; either spelling (''Isoetes'' or ''Isoëtes'') is correct. Description Quillworts are mostly aquatic or semi-aquatic in clear ponds and slow-moving streams, though several ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Specimen
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...
