Buckleya Distichophylla
''Buckleya distichophylla'', commonly called piratebush, is a flowering plant in the family Santalaceae, native to the Southern United States. It is a rare plant, found only in sporadic mountainous areas of North Carolina, Tennessee, and Virginia. ''Buckleya distichophylla'' is a deciduous shrub growing to heights of up to , with leaves that are 2-4 inches (5.1-10.2 cm) in length requiring direct sunlight to grow. Its flowers are long with 4 yellow-green, long narrow bracts. What makes the piratebush unique is in how it survives. The plant does not survive on photosynthesis only as its pale green leaves indicate less chlorophyll than other plants. In addition to photosynthesis, piratebush receives nutrients through parasitizing other species. The plant is hemiparasitic, attaching itself to the root systems of other plants with structures called haustoria and draw nutrients through them. Although originally thought to attach itself only to hemlock trees, it has since been determ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santalaceae
The Santalaceae, sandalwoods, are a widely distributed family of flowering plants (including small trees, shrubs, perennial plants, perennial herbs, and epiphyte, epiphytic climbersHewson & George [et al.]''Santalaceae'' taxonomy, 1984, pp. 191-194.) which, like other members of Santalales, are partially parasitic on other plants. Its flowers are bisexual or, by abortion ("flower drop"), unisexual.Pilger, R''Santalaceae''(with 17 figures). R. Br. Prodr. Fl. Nov. Holl. (1810) 350, pp. 1-45. Modern treatments of the Santalaceae include the family Viscaceae (mistletoes), previously considered distinct. The APG II system of 2003 recognises the family and assigns it to the order Santalales in the clade core eudicots. However, the circumscription by APG is much wider than accepted by previous classifications, including the plants earlier treated in families Eremolepidaceae and Viscaceae. It includes about 1,000 species in 43 genera. Many have reported traditional and cultural uses, inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Botsford Buckley
Samuel Botsford Buckley (May 9, 1809 – February 18, 1884) was an American botanist, geologist, and naturalist. Buckley was born in Torrey, New York, on May 9, 1809. He graduated from Wesleyan University in 1836. He received a Ph.D. from Waco University in 1872. Buckley investigated the botany of the southern United States and discovered many new species of plants and mollusks. The plant genus '' Buckleya'' was named in his honor. Buckley determined the height of several summits in the Great Smoky Mountains, including Mount Buckley which was named in his honor. Buckley served as an assistant to Texas chief geologist Benjamin Franklin Shumard. He named an oak species after Shumard in 1860, but then stymied Shumard's reappointment under newly-elected Governor Sam Houston. Buckley was the Texas state geologist from 1860 to 1861 and 1874 to 1877. He was the scientific editor of the ''State Gazette'' in Austin, Texas Austin ( ) is the List of capitals in the United S ...

Torr
The torr (symbol: Torr) is a Pressure#Units, unit of pressure based on an absolute scale, defined as exactly of a standard atmosphere (unit), atmosphere (101325 Pa). Thus one torr is exactly (≈ ). Historically, one torr was intended to be the same as one "millimetre of mercury", but subsequent redefinitions of the two units of measurement, units made the torr marginally lower (by less than 0.000015%). The torr is not part of the International System of Units (SI). Even so, it is often combined with the metric prefix milli to name one millitorr (mTorr), equal to 0.001 Torr. The unit was named after Evangelista Torricelli, an Italian physicist and mathematician who discovered the principle of the barometer in 1644. Nomenclature and common errors The unit name ''torr'' is written in letter case, lower case, while its symbol ("Torr") is always written with an uppercase initial; including in combinations with prefixes and other unit symbols, as in "mTorr" (millitorr) or " ...

Shrub
A shrub or bush is a small to medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple Plant stem, stems and shorter height, less than tall. Small shrubs, less than tall are sometimes termed as subshrubs. Many botany, botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some define a shrub as less than and a tree as over 6 m. Others use as the cutoff point for classification. Many trees do not reach this mature height because of hostile, less than ideal growing conditions, and resemble shrub-sized plants. Others in such species have the potential to grow taller in ideal conditions. For longevity, most shrubs are classified between Perennial plant, perennials and trees. Some only last about five years in good conditions. Others, usually larger and more woody, live beyond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioecious
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...
