Niebla Usneoides
''Niebla usneoides'' is a fruticose lichen that grows on rocks in the fog zone along the Pacific Coast of Baja California in the Vizcaíno Desert and Magadalena Desert regions, and reported also from the Channel Islands and mainland of southern California.Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14 The epithet, '' usneoides'' is in reference to the similarity to the lichen genus ''Usnea''. Distinguishing features ''Niebla usneoides'' is distinguished by a thallus divided into numerous subtubular more or less linear shaped branches, to 4 cm high and 8 cm across, that are fringed above with spiculiform branchlets and by short coralloid isidia (isidium) along margins. The branches become terminally whip-like, or abruptly curved. Pycnidia and apothecia are absent. Similar species are '' Niebla suffnessii'' and ''Niebla isidiaescens''. ''Niebla suffnessii'' is viewed as the fertile coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruticose Lichen
A fruticose lichen is a form of lichen fungi that is characterized by a coral-like shrubby or bushy growth structure. It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts. Fruticose lichens are not a monophyletic and holophyletic lineage, but is a form encountered in many classes. Fruticose lichens have a complex vegetation structure, and are characterized by an ascending, bushy or pendulous appearance. As with other lichens, many fruticose lichens can endure high degrees of desiccation. They grow slowly and often occur in habitats such as on tree barks, on rock surfaces and on soils in the Arctic and mountain regions. Characteristics Fruticose lichens are lichens composed of a shrubby or bushy thallus and a holdfast. The thallus is the vegetative body of a lichen that does not have true leaves, stems, or roots. The thallus colour is affected by the algae in the lichen, compounds created by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encelia
''Encelia'' is a genus of the plant family Asteraceae. It consists of shrubs (and one geophyte) of arid environments in southwestern North America and western South America. All have n = 18 chromosomes. All the North American species are obligate outcrossers. In cultivation, the species readily form fertile F1 hybrids, F2s, and backcrosses, but in natural areas of sympatry, F2s and backcrosses are absent or rare. ''Encelia'' species are used as food plants by the larvae of some Lepidoptera species including the leaf miner '' Bucculatrix enceliae'' which feeds exclusively on ''Encelia farinosa''. The phylogenetic sister group of ''Encelia'' is a clade comprising the genera '' Enceliopsis'' and ''Geraea''. The three genera are informally called the "Encelia alliance". ''Encelia'' is named in honor of German biologist Christophorus Enzelius, 1517–1583. ;Species *''Encelia actoni'' Elmer - California *'' Encelia asperifolia'' (S.F.Blake) C.

Lichens Of North America
Irwin M. Brodo (born 1935) is an emeritus scientist at the Canadian Museum of Nature, in Ottawa, Ontario, Canada. He is an authority on the identification and biology of lichens. Irwin Brodo was honored in 1994 with an Acharius Medal presented to him by the International Association for Lichenology. Brodo did his undergraduate studies at Columbia University, and received a master's degree from Cornell University. He earned a Ph.D. in lichenology under the supervision of Henry Imshaug at Michigan State University. He later went on to teach at Université Laval and the University of Alaska, and he also supervised master's students at the University of Ottawa and Carleton University.

Propagules
In biology, a propagule is any material that functions in propagating an organism to the next stage in its life cycle, such as by dispersal. The propagule is usually distinct in form from the parent organism. Propagules are produced by organisms such as plants (in the form of seeds or spores), fungi (in the form of spores), and bacteria (for example endospores or microbial cysts). In disease biology, pathogens are said to generate infectious propagules, the units that transmit a disease. These can refer to bacteria, viruses, fungi, or protists, and can be contained within host material. For instance, for influenza, the infectious propagules are carried in droplets of host saliva or mucus that are expelled during coughing or sneezing. In horticulture, a propagule is any plant material used for the purpose of plant propagation. In asexual reproduction, a propagule is often a stem cutting. In some plants, a leaf section or a portion of root can be used. In sexual reproduction, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niebla Homalea
''Niebla homalea'' is a species of fruticose lichen that grows on rocks in foggy areas along the Pacific Coast of North America, from Mendocino County, California south to Bahía de San Quintín on the main peninsula of Baja California, with an isolated occurrence further south on vertical rock faces above Punta Camachos, and other occurrences in the Channel Islands and on Guadalupe Island.Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot.

Battarraea Phalloides
''Battarrea phalloides'' is an inedible species of mushroom in the family Agaricaceae, and the type species of the genus ''Battarrea''. Known in the vernacular as the scaley-stalked puffball, sandy stiltball, or desert stalked puffball, it has a woody, slender, and shaggy or scaly stem that is typically up to in length. Although its general appearance resembles an agaric with stem and gills, atop the stem is a spore sac, consisting of a peridium and a powdery internal gleba. In maturity, the spore sac ruptures to release the spores. ''Battarrea phalloides'' is found in dry, sandy locations throughout the world, and has been collected from Africa, Asia, Australia, Europe, North America (primarily in western regions), and South America. There is currently some disagreement in the literature as to whether the European ''B. stevensii'' is the same species as ''B. phalloides''.

Petalonyx Linearis
''Petalonyx linearis'' is a species of flowering plant in the family Loasaceae known by the common name narrowleaf sandpaper plant. It is native to the deserts of eastern California, western Arizona and northwestern Mexico, where it grows in scrub and other habitat. It is a rounded clumpy subshrub made up of many rough-haired, erect stems up to a meter tall. The cylindrical stems are lined evenly with linear to widely lance-shaped leaves 1 to 2.5 centimeters long. The inflorescence at the end of each stem is a raceme of many small five-petalled white flowers surrounded by rounded or oval bract In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of ...s with pointed, lobed, or notched tips.

Eriogonum
''Eriogonum'' is a genus of flowering plants in the family Polygonaceae. The genus is found in North America and is known as wild buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. It includes some common wildflowers such as the California buckwheat (''Eriogonum fasciculatum''). The genus derived its name from the Greek word ''erion'' meaning 'wool' and ''gonu'' meaning 'knee or joint'. The author of the genus, Michaux, explained the name as describing the first named species of the genus (''E. tomentosum'') as a wooly plant with sharply bent stems (''"planta lanata, geniculata"''). Despite sharing the common name "buckwheat", ''Eriogonum'' is part of a different genus than the cultivated European buckwheat and than other plant species also called wild buckwheat. It came into the news in 2005 when the Mount Diablo buckwheat (''Eriogonum truncatum'', believed to be extinct) was rediscovered. Ecology ''Eriogonum'' spe ...
