Encelia
''Encelia'' is a genus of the Family (biology), plant family Asteraceae whose members are frequently called brittlebushes. 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 Outcrossing, outcrossers. In cultivation, the species readily form fertile F1 hybrid, F1 hybrids, F2s, and backcrossing, 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 ''Bucculatricidae, 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. ;Spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encelia Farinosa
''Encelia farinosa'' (commonly known as brittlebush, brittlebrush, or incienso), is a common desert shrub of the southwestern United States and northern Mexico. It has a variety of historical uses. Description Brittlebush grows up to tall, with fragrant leaves long, ovate to deltoid, and silvery tomentose. Arranged in loose panicles above the leafy stems, the capitula are in diameter. Each has 8–18 orange-yellow ray florets, in length, and yellow or purple-brown disc florets. The fruit measures and no pappus is visible. During dry seasons the plant goes drought deciduous, shedding all of its foliage, relying on the water stored in its thick stems. '' Encelia californica'' is similar, but has only one flower head per stalk. Chemistry The leaves contain 3-Acetyl-6-methoxybenzaldehyde. Taxonomy Varieties Two varieties of ''E. farinosa'' are recognized by ''Flora of North America''. *''Encelia farinosa'' var. ''farinosa'' – yellow disc florets *''Encelia f ...

Encelia Actoni
''Encelia actoni'', also known by the common names Acton brittlebush and Acton encelia, is a species of flowering plant in the family Asteraceae. It is sometimes misspelled ''Encelia actonii''. Distribution and habitat The plant is native to southern California and neighboring areas of Nevada in the U.S. and Baja California in México. It grows in various types of open habitat, including deserts, chaparral, and grasslands. It is found in the Mojave Desert, Sonoran Deserts, Peninsular Ranges, Transverse Ranges, San Joaquin Valley, and southern Sierra Nevada. The species was named for the community of Acton in Southern California, located in an ecotone of the Mojave Desert ecoregion and of the montane chaparral and woodlands in the San Gabriel Mountains. Description ''Encelia actoni'' is a multi−branched perennial shrub, reaching in height. The branches are lined with oval to roughly triangular leaves a few centimeters long, that are gray-green and woolly in texture. The ...

Enceliopsis
''Enceliopsis'' is a small genus of flowering plants in the family Asteraceae. They are sometimes called sunrays. They are similar to the daisylike plants in the related genus '' Encelia''. These three shrubs are native to the western United States and Canada.Nelson, Aven. 1909.

Lepidoptera
Lepidoptera ( ) or lepidopterans is an order (biology), order of winged insects which includes butterflies and moths. About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, making it the second largest insect order (behind Coleoptera) with 126 family (biology), families and 46 Taxonomic rank, superfamilies, and one of the most widespread and widely recognizable insect orders in the world. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, large triangular Insect wing, wings, and a proboscis for siphoning nectars. The scales are modified, flattened "hairs", and give butterflies and moths their wide variety of colors and patterns. Almost all species have some form of membranous wings, except for a few that have reduced wings or are wingless. Mating and the laying of eggs is normally performe ...

Donald W
Donald is a Scottish masculine given name. It is derived from the Gaelic name ''Dòmhnall''.. This comes from the Proto-Celtic *''Dumno-ualos'' ("world-ruler" or "world-wielder"). The final -''d'' in ''Donald'' is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers. A short form of Donald is Don, and pet forms of Donald include Donnie and Donny. The feminine given name Donella is derived from Donald. ''Donald'' has cognates in other Celtic languages: Modern Irish ''Dónal'' (anglicised as ''Donal'' and ''Donall'');. Scottish Gaelic ''Dòmhnall'', ''Domhnull'' and ''Dòmhnull''; Welsh '' Dyfnwal'' and Cumbric ''Dumnagual''. Although the feminine given name '' Donna'' is sometimes used as a feminine form of ''Donald'', the names are not etymologically related. Variations Kings and noblemen Domnall or Domhnall is the name of many ancient and medieval Gaelic kings and noblemen: * Dyfnwal Moelmud (Dunvallo Molmutius), legendary kin ...

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...
