Carex Reznicekii
''Carex reznicekii'', known as Reznicek's sedge, is a species of '' Carex'' native to North America. It is a perennial. Described initially from a New York population, this species was named in 2006 in honor of the botanist Anton Reznicek, a specialist in the genus ''Carex''. Description This species resembles '' Carex umbellata'' and '' Carex nigromarginata''. ''C. reznicekii'' can be readily distinguished from ''C. umbellata'' by the absence of basal spikes observable on ''C. reznicekii''. ''C. reznicekii'' most strongly resembles ''C. nigromarginata'', but can be differentiated by several factors, including ''C. reznicekii's'' narrower leaves and more-or-less uniform culm lengths. ''C. reznicekii's'' species status and distribution was determined in part through the use of herbaria records, where many instances of ''C. reznicekii'' were erroneously identified as ''C. umbellata'' and ''C. nigromarginata''.

Carex
''Carex'' is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges, however those of genus ''Carex'' may be called true sedges, and it is the most species-rich genus in the family. The study of ''Carex'' is known as caricology. Description All species of ''Carex'' are perennial, although some species, such as '' C. bebbii'' and '' C. viridula'' can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section. The leaves of ''Carex'' comprise a blade, which extends away from the stalk, and a sheath, which encloses part of the stalk. The blade is normally long and flat, but may be folded, inrolled, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anton Reznicek
Anton 'Tony' Albert Reznicek (born 1950) is a botanist known best for his work on the sedge genus '' Carex'' and co-authorship of the ''Field Manual of Michigan Flora''. He is currently curator emeritus at the University of Michigan Herbarium. Education Reznicek's higher education began at the University of Guelph, where he received his bachelor's with honors in 1971. He completed his master's at the University of Toronto, where he completed his thesis ''The Taxonomy of Carex Series Lupulinae in Canada'' in 1973. Moving forward, he completed his Ph.D., also at the University of Toronto, where he wrote ''The Taxonomy of the Stellulatae group of Carex in North America''. While at the University of Toronto, Reznicek met his wife Susan, a botanist herself who was studying arctic ecology. Scholarship Reznicek has worked broadly in the field of botany, but is best known for his work on sedges, specifically the genus ''Carex''. His work looks broadly at the systematics and evolution w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carex Nigromarginata
''Carex nigromarginata'' is a North American sedge which grows on acid soils in dry woodland, thickets, and roadside, and similar ruderal habitats in partial shade or in full sun, often near streams at elevations of . The plants grow in dense clumps, often forming circular patterns on forest floors or roadsides. 2''n'' = 36.Ball, P. W. 2002. ''Carex nigromarginata''.

Herbaria
A herbarium (plural: herbaria) is a collection of preserved plant specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called '' exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxa; some specimens may be types. The same term is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of horticultural origin. History The making of herbaria is an ancient phenomenon, at least six centuries old, although the techniques have change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connecticut
Connecticut () is the southernmost state in the New England region of the Northeastern United States. It is bordered by Rhode Island to the east, Massachusetts to the north, New York to the west, and Long Island Sound to the south. Its capital is Hartford and its most populous city is Bridgeport. Historically the state is part of New England as well as the tri-state area with New York and New Jersey. The state is named for the Connecticut River which approximately bisects the state. The word "Connecticut" is derived from various anglicized spellings of "Quinnetuket”, a Mohegan-Pequot word for "long tidal river". Connecticut's first European settlers were Dutchmen who established a small, short-lived settlement called House of Hope in Hartford at the confluence of the Park and Connecticut Rivers. Half of Connecticut was initially claimed by the Dutch colony New Netherland, which included much of the land between the Connecticut and Delaware Rivers, although the firs ...
