Grace Wigglesworth
Grace Wigglesworth (1877 – aft. 1950) was an English palaeobotanist who published on early land plants, especially bryophytes. She spent over thirty years working as a curator at the Manchester Museum, where she cared for and published for botanical collections in the Herbarium. Education and early career Educated at Manchester High School, she studied at Owens College, gaining a BSc in 1903 and an MSc in palaeobotany in 1906. She was one of several women supported in their studies by Manchester’s botany professor, William Henry Lang. Wigglesworth was an honorary research fellow at the University until 1907, during which time she published several papers on early land plants. From 1907 – 1910 she had a stint as botany lecturer at the London Day Training College. Manchester Museum From 1910 to 1944 she was Assistant Keeper at the Manchester Museum, where she fostered links between the botany, geology and zoology departments, also giving public lectures and demonstrat ...

Sphaerocarpales
Sphaerocarpales is an order of plants within the liverworts. Approximately twenty species are in this order which is sub-divided into four families Family (from ) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). It forms the basis for social order. Ideally, families offer predictability, structure, and safety as ...: Monocarpaceae, Sphaerocarpaceae and Riellaceae, as well as the extinct family Naiaditaceae. The inclusion of the Naiaditaceae is uncertain, and the family has sometimes been assigned to the Calobryales.

Natural History Of The Peninsular Ranges
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 t ...

Bryophyta may refer to: * Bryophytes – Bryophyta ''sensu lato'' (in the broad sense); a group of plants regarded as a single division by some, but further split into: ** Mosses – Bryophyta ''sensu stricto'' (in the strict sense); a specific group of leafy nonvascular plants, now regarded as Division Bryophyta **hornworts (Anthocerotophyta) **liverworts (Marchantiophyta Liverworts are a group of non-vascular plant, non-vascular embryophyte, land plants forming the division Marchantiophyta (). They may also be referred to as hepatics. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in wh ...

Endemic Flora Of California
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomi ...

Geothallus
''Geothallus'' is a monotypic genus of liverwort in the family Sphaerocarpaceae family. It includes only the single species ''Geothallus tuberosus''. Its common name is Campbell's liverwort.

Marchantiophyta
Liverworts are a group of non-vascular plant, non-vascular embryophyte, land plants forming the division Marchantiophyta (). They may also be referred to as hepatics. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. The division name was derived from the genus name ''Marchantia'', named after his father by French botanist Jean Marchant. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (botany), costa (present in many mosses) and may bear marginal cilia (botany), cilia (very rare i ...

Coastal Sage Scrub
Coastal sage scrub, also known as coastal scrub, CSS, or soft chaparral, is a low scrubland plant community of the California coastal sage and chaparral subecoregion, found in coastal California and northwestern coastal Baja California. It is within the California chaparral and woodlands ecoregion, of the Mediterranean forests, woodlands, and scrub biome. Characteristics ;Plant community Coastal sage scrub is characterized by low-growing aromatic, and drought-deciduous shrubs adapted to the semi-arid Mediterranean climate of the coastal lowlands. The community is sometimes called "soft chaparral" due to the predominance of soft, drought-deciduous leaves in contrast to the hard, waxy-cuticled leaves on sclerophyllous plants of California's chaparral communities. ;Flora Characteristic shrubs and subshrubs include: * California sagebrush (''Artemisia californica'') * Black sage (''Salvia mellifera'') * White sage (''Salvia apiana'') * California buckwheat (''Eriogonum fasci ...
