Polemonium Eddyense
''Polemonium eddyense'' is a perennial wildflower species in the family Polemoniaceae with the common name Mount Eddy sky pilot. It is endemic to a small area around Mount Eddy, California. Description ''Polemonium eddyense'' is a small herb with a dense tuft of highly divided hairy leaves. The flowers are held in a tight cluster above the foliage and each flower has 5 symmetric petals and is blue with a yellow center and has prominent yellow anthers. Range and habitat ''Polemonium eddyense'' is endangered and is found growing on and near Mount Eddy in California on rocky serpentine soil Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup, especially anti ...s.

Rebecca L
Rebecca, ; Syriac: , ) from the Hebrew (lit., 'connection'), from Semitic root , 'to tie, couple or join', 'to secure', or 'to snare') () appears in the Hebrew Bible as the wife of Isaac and the mother of Jacob and Esau. According to biblical tradition, Rebecca's father was Bethuel the Aramean from Paddan Aram, also called Aram-Naharaim. Rebecca's brother was Laban the Aramean, and she was the granddaughter of Milcah and Nahor, the brother of Abraham. Rebecca and Isaac were one of the four couples that some believe are buried in the Cave of the Patriarchs, the other three being Adam and Eve, Abraham and Sarah, and Jacob and Leah. Early life After the Binding of Isaac, Sarah died. After taking care of her burial, Abraham went about finding a wife for his son Isaac, who was already 37 years old. He commanded his servant (whom the Torah commentators identify as Eliezer of Damascus) to journey to his birthplace of Aram Naharaim to select a bride from his own family, rather than ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polemoniaceae
The Polemoniaceae (Jacob's-ladder or phlox family) are a family of flowering plants consisting of about 25 genera with 270–400 species of annuals and perennials native to the Northern Hemisphere and South America, with the center of diversity in western North America. Only one genus (''Polemonium'') is found in Europe, and two (''Phlox'' and ''Polemonium'') in Asia, where they are confined to cool temperate to arctic regions; both genera also occur more widely in North America, suggesting relatively recent colonization of the Old World from North America. The family can be distinguished from most other eudicot families by the ovary made up of three fused carpels (usually with three chambers, but with one chamber in some species). The members of the family have five sepals, five petals fused, and five stamens that alternate with the lobes of the corolla. For decades, most sources used a classification of the family published by Grant in 1959, but new evidence, including mol ...

Mount Eddy
Mount Eddy is the highest peak of the Trinity Mountains, a mountain range of the Klamath Mountains System, located in Siskiyou County, and Trinity County in northern California. The mountain is in the Mount Eddy RNA, a Research Natural Area on the Shasta-Trinity National Forest, a unit of the United States Forest Service. Geography The summit rises to an elevation of , and is the highest point in Trinity County, the ninth most prominent peak in California, and the highest summit west of Interstate 5 in the United States. The peak is west of Mount Shasta City and the massive Mount Shasta volcano. It is protected within the Shasta-Trinity National Forest. The mountain receives heavy snowfall during the winter due to its altitude. The mountain is named in honor of Olive Paddock Eddy, who is mistakenly held to be the first woman to climb Mount Shasta. She was 8 months pregnant at the time that she is credited with climbing the volcano. Harriet Catherine Eddy was actually ...

Serpentine Soil
Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup, especially antigorite, lizardite, and chrysotile or white asbestos, all of which are commonly found in ultramafic rocks. The term "serpentine" is commonly used to refer to both the soil type and the mineral group which forms its parent materials. Serpentine soils exhibit distinct chemical and physical properties and are generally regarded as poor soils for agriculture. The soil is often reddish, brown, or gray in color due to its high iron and low organic content. Geologically, areas with serpentine bedrock are characteristically steep, rocky, and vulnerable to erosion, which causes many serpentine soils to be rather shallow. The shallow soils and sparse vegetation lead to elevated soil temperatures and dry conditions. Due to their ultramafic origin, ser ...

Polemonium
''Polemonium'', commonly called Jacob's ladders or Jacob's-ladders (the name derived from the Biblical story), is a genus of between 25 and 40 species of flowering plants in the family Polemoniaceae, native to cool temperate to arctic regions of the Northern Hemisphere. One species also occurs in the southern Andes in South America. Many of the species grow at high altitudes, in mountainous areas. Most of the uncertainty in the number of species relates to those in Eurasia, many of which have been synonymized with '' Polemonium caeruleum''. ''Polemonium'' are perennial plants (rarely annual plants) growing 10–120 cm tall with bright green leaves divided into lance-shaped leaflets. They produce blue (rarely white or pink) flowers in the spring and summer. Some species are used as food plants by the larvae of some Lepidoptera species including '' Coleophora polemoniella''. Species Kew's Plants of the World Online accepts 37 species. Many are locally known sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of California
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
