Sisyrinchium Campestre
''Sisyrinchium campestre'', the prairie blue-eyed grass or white-eyed grass, is a small herbaceous perennial plant in the iris family, native to prairie and meadow in the central United States and in extreme southern Manitoba. Prairie blue-eyed grass is one of the more drought tolerant species in the genus. It blooms in late spring and early summer for about three weeks. The flowers are white to pale blue, with yellow centers. They have six tepals long that have rounded ends with a sharp point in the center. The flowers are borne on slender pedicels (stems) in an umbel enclosed in two bract In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of ...s at the top of an unbranched flat stem. The leaves are grass-like, long and across, and the flower stem is about as long as or a little l ...

Nathaniel Lord Britton
Nathaniel Lord Britton (January 15, 1859 – June 25, 1934) was an American botanist and taxonomist who co-founded the New York Botanical Garden in the Bronx, New York. Early life Britton was born in New Dorp in Staten Island, New York to Jasper Alexander Hamilton Britton and Harriet Lord Turner. His parents wanted him to study religion, but he was attracted to nature study at an early age. He was a graduate of the Columbia University School of Mines and afterwards taught geology and botany at Columbia University. He joined the Torrey Botanical Club soon after graduation and was a member his entire life. He married Elizabeth Gertrude Knight, a bryologist, on August 27, 1885. They had met when she joined the club and were lifelong collaborators in botanical research. New York Botanical Garden During their honeymoon in 1888, they visited Kew Gardens, which led to his wife proposing a botanical garden for New York at a Torrey Club meeting. Together, they campaigned to bring ...

Addison Brown
Addison C. Brown (February 21, 1830 – April 9, 1913) was a United States district judge of the United States District Court for the Southern District of New York, a botanist, and a serious amateur astronomer. Early life, education and career Addison Brown was born on February 21, 1830, in West Newbury, Massachusetts, the oldest of five children of Addison Brown Sr., a shoemaker, and Catherine Babson Griffin, both descended from Massachusetts' earliest Pilgrim settlers. He attended West Newbury's one-room school until he had exhausted its offerings at age 12. In 1843 he began more advanced studies in such areas as Latin, physics, algebra, and philosophy. In 1848 Brown entered Amherst College, intending from the start to transfer to Harvard University in his sophomore year. While at Harvard, Brown earned money as the college organist and unhappily spent some summer months as a village school teacher. Brown befriended and roomed with his Harvard classmate Horatio Alger and count ...

Sisyrinchium Campestre And Pedicularis Canadensis In Bloom
''Sisyrinchium'' is a large genus of annual to perennial flowering plant in the family Iridaceae. Native to the New World, the species are known as blue-eyed grasses and, though not true grasses and in varieties with flower colors other than blue, are monocots. Several species in the eastern United States are threatened or endangered. Description These are not true grasses, but many species have the general appearance of grasses, as they are low-growing plants with long, thin leaves. They often grow on grasslands. Many species resemble irises, to which they are more closely related. Most species grow as perennial plants, from a rhizome, though some are short-lived (e.g. ''Sisyrinchium striatum)'', and some are annuals (e.g. '' Sisyrinchium iridifolium''). The flowers are relatively simple and often grow in clusters. Many species, particularly the South American ones, are not blue, despite the common name. The genus includes species with blue, white, yellow, and purple ...

Herbaceous
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the p ...

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 ...

Iris Family
Iridaceae is a family of plants in order Asparagales, taking its name from the irises, meaning rainbow, referring to its many colours. There are 66 accepted genera with a total of c. 2244 species worldwide (Christenhusz & Byng 2016). It includes a number of other well known cultivated plants, such as freesias, gladioli and crocuses. Members of this family are perennial plants, with a bulb, corm or rhizome. The plants grow erect, and have leaves that are generally grass-like, with a sharp central fold. Some examples of members of this family are the blue flag and yellow flag. Name and history The family name is based on the genus '' Iris'', the largest and best known genus in Europe. This genus dates from 1753, when it was coined by Swedish botanist, Carl Linnaeus. Its name derives from the Greek goddess, Iris, who carried messages from Olympus to earth along a rainbow, whose colours were seen by Linnaeus in the multi-hued petals of many of the species. The family is curren ...

Prairie
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Ukraine, Russia and Kazakhstan. Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, hillier land to the east. In the U.S., the area is constituted by most or all of the states of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas, Missouri, Iowa, Illinois, Indiana, Wisconsin, and western and southern Minnesota. The Palouse of Washington and ...

Meadow
A meadow ( ) is an open habitat, or field, vegetated by grasses, herbs, and other non- woody plants. Trees or shrubs may sparsely populate meadows, as long as these areas maintain an open character. Meadows may be naturally occurring or artificially created from cleared shrub or woodland. They can occur naturally under favourable conditions (see perpetual meadows), but they are often maintained by humans for the production of hay, fodder, or livestock. Meadow habitats, as a group, are characterized as "semi-natural grasslands", meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife, and support flora and fauna that could not thrive in other habitats. They are ecologically important as they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering, if the vegetation is high enough. There are multiple types of mead ...

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in '' Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undi ...

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a " jack-o'-lantern".

Umbel
In botany, an umbel is an inflorescence that consists of a number of short flower stalks (called pedicels) that spread from a common point, somewhat like umbrella ribs. The word was coined in botanical usage in the 1590s, from Latin ''umbella'' "parasol, sunshade". The arrangement can vary from being flat-topped to almost spherical. Umbels can be simple or compound. The secondary umbels of compound umbels are known as umbellules or umbellets. A small umbel is called an umbellule. The arrangement of the inflorescence in umbels is referred to as umbellate, or occasionally subumbellate (almost umbellate). Umbels are a characteristic of plants such as carrot, parsley, dill, and fennel in the family Apiaceae; ivy, '' Aralia'' and '' Fatsia'' in the family Araliaceae; and onion (''Allium'') in the family Alliaceae. An umbel is a type of indeterminate inflorescence. A compressed cyme, which is a determinate inflorescence, is called umbelliform if it resembles an umbel. Gallery ...
