Thaddeus William Harris
Thaddeus William Harris (November 12, 1795 – January 16, 1856) was an American entomologist and librarian. His focus on insect life cycles and interactions with plants was influential in broadening American entomological studies beyond a narrow taxonomic approach. He was an early agricultural entomologist and served as a mentor and role model for others in this new field. For 25 years Harris served as the librarian of Harvard University where oversaw the rapid growth of the library and introduced one of the earliest American library card catalogs.Elliott 2000 Life and career Thaddeus William Harris was born in Dorchester, Massachusetts on November 12, 1795. His father, Thaddeus Mason Harris, was a Unitarian minister who served at the church on Meeting House Hill and had also for a time served as librarian of Harvard. Harris himself received his undergraduate degree at Harvard in 1815, and then went on to study medicine there, receiving his M.D. in 1820. He went into medical pr ...

Ulmus Americana
''Ulmus americana'', generally known as the American elm or, less commonly, as the white elm or water elm, is a species of elm native to eastern North America, naturally occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. The American elm is an extremely hardy tree that can withstand winter temperatures as low as −42 ° C (−44 ° F). Trees in areas unaffected by Dutch elm disease (DED) can live for several hundred years. A prime example of the species was the Sauble Elm, which grew beside the banks of the Sauble River in Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to DED; when it was felled in 1968, a tree-ring count established that it had germinated in 1701. For over 80 years, ''U. americana'' had been identified as a tetraploid, i.e. having double the usual number of chromosomes, making it unique within the genus. However, a study published in 2011 by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Thaddeus William Harris
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Polygonia interrogationis'', commonly called the question mark butterfly, is a North American nymphalid butterfly. It lives in wooded areas, city parks, generally in areas with a combination of trees and open space. The color and textured appearance of the underside of its wings combine to provide camouflage that resembles a dead leaf. The adult butterfly has a wingspan of . Its flight period is from May to September.

Pilea Pumila
''Pilea pumila'', commonly known as clearweed, Canadian clearweed, coolwort or richweed, is an herbaceous plant in the nettle family (Urticaceae). It is native to Asia and eastern North America, where it is broadly distributed. This plant is most often found in rich loamy soil, usually in moist to wet areas. Its natural habitat is in forests or other lightly shaded conditions. It is a common plant throughout its range, and forms large colonies where it is found. It grows in both high-quality habitats and in ecologically degraded areas. Due to its high tolerance for disturbance, it is often seen near buildings and as a garden weed. Description ''Pilea pumila'' is an erect annual, growing 0.7 to 70 cm tall. The foliage is opposite, simple with dentate margins, wrinkly (with depressed veins), ovate, and with long petioles. Both the leaves and stems are translucent and bright green, turning bright yellow in autumn. The flowers are small, borne in axillary cymes, unisexual with ...

Urtica
''Urtica'' is a genus of flowering plants in the family Urticaceae. Many species have stinging hairs and may be called nettles or stinging nettles, although the latter name applies particularly to ''Urtica dioica''. ''Urtica'' species are food for the caterpillars of numerous Lepidoptera (butterflies and moths), such as the tortrix moth ''Syricoris lacunana'' and several Nymphalidae, such as ''Vanessa atalanta'', one of the red admiral butterflies. The generic name ''Urtica'' derives from the Latin for sting. Description ''Urtica'' species grow as annuals or perennial herbaceous plants, rarely shrubs. They can reach, depending on the type, location and nutrient status, a height of . The perennial species have underground rhizomes. The green parts have stinging hairs. Their often quadrangular stems are unbranched or branched, erect, ascending or spreading. Most leaves and stalks are arranged across opposite sides of the stem. The leaf blades are elliptic, lanceolate, ovate or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ribes
''Ribes'' is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere. The various species are known as currants or gooseberries, and some are cultivated for their edible fruit or as ornamental plants. ''Ribes'' is the only genus in the family Grossulariaceae. Description ''Ribes'' species are medium shrublike plants with marked diversity in strikingly diverse flowers and fruit. They have either palmately lobed or compound leaves, and some have thorns. The sepals of the flowers are larger than the petals, and fuse into a tube or saucer shape. The ovary is inferior, maturing into a berry with many seeds. Taxonomy ''Ribes'' is the single genus in the Saxifragales family Grossulariaceae. Although once included in the broader circumscription of Saxifragaceae ''sensu lato'', it is now positioned as a sister group to Saxifragaceae ''sensu stricto''.
