Hesperolinon Drymarioides
''Hesperolinon drymarioides'' is a rare species of flowering plant in the flax family known by the common names drymary dwarf flax and drymaria-like western flax; it is named for its resemblance to genus '' Drymaria''. It is endemic to California California is a state in the Western United States, located along the Pacific Coast. With nearly 39.2million residents across a total area of approximately , it is the most populous U.S. state and the 3rd largest by area. It is also the m ..., where it grows in the central inland North Coast Range. Most of the few known occurrences have been noted in Lake County. It is a plant of serpentine soils in chaparral and woodland ecosystems. This is a small annual herb growing a thin branching brown stem low to the ground or erect to about 20 centimeters in height.

John Kunkel Small
John Kunkel Small (January 31, 1869 – January 20, 1938) was an American botanist. Born on January 31, 1869, in Harrisburg Pennsylvania, Kunkel studied botany at Franklin & Marshall College and Columbia University. He was the first Curator of Museums at The New York Botanical Garden, a post in which he served from 1898 until 1906. From 1906 to 1934 he was Head Curator and then from 1934 until his death he was Chief Research Associate and Curator. Small's doctoral dissertation, published as '' Flora of the Southeastern United States'' in 1903, anrevised in 1913and 1933, remains the best floristic reference for much of the South. Assisted by the patronage of Charles Deering, Small traveled extensively around Florida recording plants and land formations. Small was an early botanist explorer of Florida, documenting many things for the first time, although the flora and fauna were well known to the local Seminole Indians. His first trip to the region was in 1901. Over the next 37 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linaceae
Linaceae is a family of flowering plants. The family is cosmopolitan, and includes about 250 species in 14 genera, classified into two subfamilies: the Linoideae and Hugonioideae (often recognized as a distinct family, the Hugoniaceae). Leaves of the Linaceae are always simple; arrangement varies from alternate (most species) to opposite (in ''Sclerolinon'' and some ''Linum'') or whorled (in some ''Hesperolinon'' and ''Linum'' species). The hermaphroditic, actinomorphic flowers are pentameric or, very rarely, tetrameric (e.g., ''Radiola linoides'', ''Linum keniense''). In the Linoideae, the largest genus is ''Linum'', the flaxes, with 180–200 species including the cultivated flax, ''Linum usitatissimum''. Members of the Linoideae include herbaceous annuals and perennials, as well as woody subshrubs, shrubs, and small trees (''Tirpitzia'') inhabiting temperate and tropical latitudes of Eurasia, Africa, Australia, and the Americas. The largest genus of the Hugonioideae is ''Hugon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California Coast Ranges
The Coast Ranges of California span from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains. Physiographically, they are a section of the larger Pacific Border province, which in turn is part of the larger Pacific Mountain System physiographic division. UNESCO has included the "California Coast Ranges Biosphere Reserve" in its Man and the Biosphere Programme of World Network of Biosphere Reserves since 1983. * Physiography The northern end of the California Coast Ranges overlap the southern end of the Klamath Mountains for approximately 80 miles on the west. They extend southward for more than 600 miles to where the coastline turns eastward along the Santa Barbara Channel, around the area of Point Conception. Here the southern end meets the Los Angeles Transverse Ranges, or ''Sierras de los Angeles''. The rocks themselves that com ...

Lake County, California
Lake County is a county located in the north central portion of the U.S. state of California. As of the 2020 census, the population was 68,163. The county seat is Lakeport. The county takes its name from Clear Lake, the dominant geographic feature in the county and the largest non-extinct natural lake wholly within California. (Lake Tahoe is partially in Nevada; the Salton Sea was formed by flooding; Tulare Lake was drained by the agricultural industry.) Lake County forms the Clearlake, California micropolitan statistical area. It is directly north of the San Francisco Bay Area. Lake County is part of California's Wine Country, which also includes Napa, Sonoma, and Mendocino counties. It includes five American Viticultural Areas and over 35 wineries. History Lake County has been inhabited by Pomo Native Americans for over ten thousand years. Pomos had been fishermen and hunters, known especially for their intricate basketry made from lakeshore tules and other native plan ...

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 ...

Chaparral
Chaparral ( ) is a shrubland plant community and geographical feature found primarily in the U.S. state of California, in southern Oregon, and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate (mild wet winters and hot dry summers) and infrequent, high-intensity crown fires. Chaparral features summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found often on drier, southern facing slopes within the chaparral biome. Three other closely related chaparral shrubland systems occur in central Arizona, western Texas, and along the eastern side of central Mexico's mountain chains (mexical), all having summer rains in contrast to the Mediterranean climate of other chaparral formations. Chaparral comprises 9% of California's wildland vegetation and contains 20% of its plant species. The name comes from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Hesperolinon
''Hesperolinon'' is a genus in the family Linaceae, whose common genus names are dwarf-flax or western flax, in reference to their distribution along the west coast of North America. There are 13 known species within this genus of wildflowers, most of which are limited to serpentine soil habitats within California, United States. Helen K. Sharsmith, 1961 ''Univ Calif Publ Bot'', 32:235–314 These annual plants are thought to be mostly self-pollinating. Description Stems vary between five and fifty centimeters in length, with thread-like to linear leaves generally alternate: the leaves are typically not planar and not clasping. Cymes are characteristically open and pedicels are somewhat thread-like and ascending. The flower has five sepals, whose margins may be minutely gland-toothed. Five petals are widely spreading between one and twelve millimeters in dimension. These yellow, white or rose colored petals each manifest three minute scales at the inner base. There are fi ...
