Scoliopus
''Scoliopus'', or fetid adderstongue, is a genus of plant within the family Liliaceae consisting of two species, '' Scoliopus bigelovii'' and '' S. hallii.'' Both are found in deep shaded forests, primarily in the coastal counties of the western United States from central California to northern Oregon. The name "''Scoliopus''" derives from the Greek words ''skolios'' and ''pous'', meaning curved foot, a reference to the shape of the pedicel. Taxonomists believe that ''Scoliopus'' is closely related to ''Calochortus'', ''Prosartes'', '' Streptopus'' and ''Tricyrtis'', which all have creeping rhizomes as well as styles that divide at the tip. Description ''Scoliopus'' has two mottled leaves at its base and a long pedicel that, over time, bends and twists so that the fruit touches the ground. The flowers, which bloom in the late winter and early spring, are pale green or yellow when fresh, lined with narrow purple or dark brown veins, with wide, spreading sepals and narrower petals, ...

Scoliopus Bigelovii
''Scoliopus bigelovii'' is a species of flowering plant in the Liliaceae, lily family known by several common names, including California fetid adderstongue, Bigelow's adderstongue, slinkpod, and brownies. It is native to California, where it is known from the Santa Cruz Mountains, parts of the San Francisco Bay Area and California Coast Ranges, North Coast Ranges. It has also been collected just over the border in Oregon.BLM: ''S. bigelovii'' It occurs in old-growth forest in the understory of Sequoia sempervirens, redwoods. It grows in mossy, moist places, often in shade. Description This herbaceous perennial plant, perennial, one of two species of ''Scoliopus'', grows from a rhizome and a small section of underground stem. The above-ground parts include two large leaves ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

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 " ...

Ovary (plants)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds that do ...

Natural History Of The San Francisco Bay Area
Nature is an inherent character or constitution, particularly of the ecosphere or the universe as a whole. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright separate and even superior to nature. During the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial Revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions ( Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn at the same time, especially after Charles Darwin. Within the various uses of the word ...
