Torr
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as exactly of a standard atmosphere (). Thus one torr is exactly (≈ ). Historically, one torr was intended to be the same as one "millimeter of mercury", but subsequent redefinitions of the two units made them slightly different (by less than ). The torr is not part of the International System of Units (SI). It is often combined with the metric prefix milli to name one millitorr (mTorr) or 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 lower case, while its symbol ("Torr") is always written with upper-case initial; including in combinations with prefixes and other unit symbols, as in "mTorr" (millitorr) or "Torr⋅L/s" (torr-litres per second). The symbol (uppercase) should be used with prefix symbols (thus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 determined that pirat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nestronia
''Nestronia'' is a monotypic genus of flowering plants in the family Santalaceae containing the single species ''Nestronia umbellula'', which is known by the common names leechbrush, nestronia, conjurer's-nut, and Indian olive.

Shrub
A shrub (often also called a 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 stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...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 herbs, and epiphytic climbersHewson & George t al.br>''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, including as medicine. Genera ...

Samuel Botsford Buckley
Samuel Botsford Buckley (May 9, 1809 – February 18, 1884) was an American botanist, geologist, and naturalist. He graduated from Wesleyan University in 1836. 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. He also was the state geologist of Texas (1860–1861); determined the height of Mount Buckley in the Great Smoky Mountains (named in his honor), in North Carolina, and several other summits; and was the scientific editor of the ''State Gazette'' in Austin, Texas Austin is the capital city of the U.S. state of Texas, as well as the seat and largest city of Travis County, with portions extending into Hays and Williamson counties.

Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half 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. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santalales Genera
The Santalales are an order of flowering plants with a cosmopolitan distribution, but heavily concentrated in tropical and subtropical regions. It derives its name from its type genus ''Santalum'' (sandalwood). Mistletoe is the common name for a number of parasitic plants within the order. Overview Many of the members of the order are parasitic plants, mostly hemiparasites, able to produce sugars through photosynthesis, but tapping the stems or roots of other plants to obtain water and minerals; some (e.g. '' Arceuthobium'') are obligate parasites, have low concentrations of chlorophyll within their shoots (1/5 to 1/10 of that found in their host's foliage), and derive the majority of their sustenance from their hosts' vascular tissues (water, micro- and macronutrients, and sucrose). Most have seeds without testae (seed coats), which is unusual for flowering plants. Classification The APG IV system of 2016 includes seven families. As in the earlier APG III system, it w ...
