Sidney Fay Blake
Sidney Fay Blake (1892–1959) was an American botanist and plant taxonomist, "recognized as one of the world's experts on botanical nomenclature." Biography Blake was born in 1892 in Stoughton, Massachusetts. In 1912, he received a bachelor's degree from Harvard University, a master's degree in 1913, and a Ph.D. in botany in 1917 with a thesis on ''Viguiera''. The same year he received his Ph.D., he started his botanical career at the Bureau of Plant Industry (United States), Bureau of Plant Industry for the United States Department of Agriculture, and worked there till he died in 1959. In 1943 he was elected president of the American Society of Plant Taxonomists. Blake published many articles and monographs but only one two-volume work, ''Geographical Guide to Floras of the World''. The first volume, co-authored by Alice C. Atwood (1876–1947), was published in 1942. The second volume, written by Blake alone, was published in 1961 two years after his death. He married the en ...

Perennial Plant
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 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of California
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erigeron
''Erigeron'' () is a large genus of plants in the family Asteraceae. It is closely related to the genus ''Aster'' and the true daisies in the genus ''Bellis''. The genus has a cosmopolitan distribution in dry, mountainous areas and grassland, with the highest diversity in North America. Etymology Its English name, fleabane, is shared with related plants in several other genera. It appears to be derived from a belief that the dried plants repelled fleas or that the plants were poisonous to fleas. The generic name ''Erigeron'' is derived from the Ancient Greek words (''êri'') "early in the morning" and (''gérōn'') "old man", a reference to the appearance of the white hairs of the fruit soon after flowering or possibly alluding to the early appearance of the seed heads. The noun is masculine, so that specific epithets should have masculine endings (e.g. ''glaucus'') to agree with it. However, authors have incorrectly used neuter endings (e.g. ''glaucum''), because the ending ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray Florets
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technically ...

Lilac (color)
Lilac is a color that is a pale violet tone representing the average color of most lilac flowers. The colors of some lilac flowers may be equivalent to the colors shown below as ''pale lilac'', ''rich lilac'', or ''deep lilac''. However, there are other lilac flowers that are colored red-violet. The first recorded use of ''lilac'' as an English color name was in 1775. The color "lilac" has an eponymous book published in 2018 by Coloratura Publisher. Variations Pale lilac Pale lilac is the color represented as ''lilac'' in the ISCC-NBS color list. The source of this color is sample 209 in the ISCC-NBS Dictionary of Color Names (1955). Bright lilac The color bright lilac (displayed on the right) is the color labeled ''lilac'' by Crayola in 1994 as one of the colors in its Magic Scent specialty box of colors.

Pseudanthium
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...

Cross Section (geometry)
In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces. Cutting an object into slices creates many parallel cross-sections. The boundary of a cross-section in three-dimensional space that is parallel to two of the axes, that is, parallel to the plane determined by these axes, is sometimes referred to as a contour line; for example, if a plane cuts through mountains of a raised-relief map parallel to the ground, the result is a contour line in two-dimensional space showing points on the surface of the mountains of equal elevation. In technical drawing a cross-section, being a projection of an object onto a plane that intersects it, is a common tool used to depict the internal arrangement of a 3-dimensional object in two dimensions. It is traditionally crosshatched with the style of crosshatching often indicating the types of materials being used. With computed ...
