Ehrendorferia Ochroleuca
''Ehrendorferia ochroleuca'' (formerly ''Dicentra ochroleuca''), commonly known as white eardrops or yellow bleeding-heart, is a biennial or perennial, native to gravelly areas in the chaparral and woodlands of California (Peninsular, Transverse, and southern Coast Ranges) and in Baja California. Description Stems and leaves are glaucous. Stems grow tall; the record is , the tallest of any species in the Fumarioideae. Leaves are pinnately divided 2–4 times. They grow in a basal rosette the first year and later also on flowering stems. Flowers are up-facing, in round clusters at the end of the stems. They have 2 round sepals and 4 dull white petals with purple tips. The 2 outer petals are pouched at the base and curved outwards at the tip. The 2 inner petals are connected at the tip and project out from between the outer petals. The flowers have no odor, unlike the closely related species '' Ehrendorferia chrysantha''. Hummingbirds visit the flowers for nectar. Seeds are tin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dicentra Chrysantha 2004-05-17
''Dicentra'' (Greek ''dís'' "twice", ''kéntron'' "spur"), known as bleeding-hearts, is a genus of eight species of herbaceous plants with oddly shaped flowers and finely divided leaves, native to eastern Asia and North America. Description Flowers have two tiny sepals and four petals. The flowers are bisymmetric: the two outer petals are spurred or pouched at the base and curved outwards or backwards at the tip, and the two inner ones with or without a crest at the tip. In ''Dicentra'', all leaves are in a basal rosette, and flowers are on leafless stalks. In other genera with bisymmetric heart-shaped flowers (''Lamprocapnos'', ''Dactylicapnos'', ''Ichtyoselmis'', ''Ehrendorferia''), leaves grow on stems as well as from the root. Each of the two compound stamens is composed of one median and two lateral half stamens fused together. The stamens and pistil are held between the inner petals. Seeds with elaiosomes are borne in long capsules. All parts are poisonous if ingested ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ehrendorferia Chrysantha
''Ehrendorferia chrysantha'' (syn. ''Dicentra chrysantha''), with the common name golden eardrops, is a biennial to perennial plant in the family Papaveraceae. It is native to dry, brushy areas prone to wildfire in diverse regions of California, and in Baja California. Description ''Dicentra chrysantha'' has a taproot. Its leaves are blue-green, with many lobed leaflets. Flowers are yellow and aromatic, with the tips of two outer petals curved outward from two central petals, borne in panicles at the top of branched stems 1.5 m tall. Seed A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiospe ...s are borne in a capsule 1–2 cm long. They usually do not germinate unless exposed to fire. References External linksJepson Manual Treatment: ''Dicentra chrysantha''* Fumarioi ...

Fumarioideae
Fumarioideae is a subfamily of the family Papaveraceae (the poppy family). It was formerly treated as a separate family, the Fumariaceae (the fumitory, fumewort or bleeding-heart family). It consists of about 575 species of herbaceous plants in 20 genera, native to the Northern Hemisphere and South Africa. The largest genus is ''Corydalis'' (with 470 species). Description Flower shape Plants in the fumitory subfamily are easily recognised by their peculiar flowers with two dissimilar pairs of petals. One or both of the outer petals is usually spurred, and the inner petals are connected at tip. There are two types of flowers. A given genus has one type or the other. ''Dicentra'' has flowers with two planes of symmetry, and ''Corydalis'' has flowers with one plane of symmetry (zygomorphic). Leaves Most species have compound leaves. Taxonomy The APG IV system of 2016 (unchanged from the earlier 1998 APG system, the 2003 APG II system, and the APG III system of 2009) includes the f ...

Plant Systematics And Evolution
''Plant Systematics and Evolution'' is a biannual peer-reviewed scientific journal covering systematic botany and evolutionary biology. The editors-in-chief are Marcus A. Koch (Heidelberg University), Martin A. Lysak, (Masaryk University), and Karol Marhold (Slovak Academy of Sciences). History The journal was established in Vienna in 1851 under founding editor-in-chief Alexander Skofitz as ' (Austrian Botanical Weekly). In 1858 the publication was renamed ' (Austrian Journal of Botany) and it continued under that title from volume 9 to 91. In 1943 and 1944, two volumes were published under the title ' (Viennese Botanical Journal). It then continued under its previous title until 1973 when it was relaunched with a more international scope under its current title. Abstracting and indexing The journal is abstracted and indexed in Agricola, Biological Abstracts, CAB Abstracts, Chemical Abstracts Service, EMBiology, International Bibliography of Periodical Literature, Scopus, Cu ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
