Drymocallis
''Drymocallis'' is a genus of plants formerly (and sometimes still) included with the typical cinquefoils (''Potentilla''). It contains three species known or suspected to be protocarnivorous, but more cinquefoils might eventually be moved here: *'' Drymocallis arguta'' (Pursh) Rydb. – tall cinquefoil, cream cinquefoil *'' Drymocallis glandulosa'' (Lindl.) Rydb. – sticky cinquefoil *'' Drymocallis rupestris'' (L.)

Drymocallis Glandulosa
''Drymocallis glandulosa'', known by the common name sticky cinquefoil and formerly as ''Potentilla glandulosa'', is a plant species in the family Rosaceae. It is native to western North America from southwestern Canada through the far western United States and California, into Baja California. It is widespread and can be found in many types of habitats. Description ''Drymocallis glandulosa'' is generally erect in form but it may be small and tuftlike, measuring just a few centimeters high, or tall and slender, approaching in height. It may or may not have rhizomes. It is usually coated in hairs, many of which are glandular, giving the plant a sticky texture. The leaves are each divided into several leaflets, with one long terminal leaflet and a few smaller ones widely spaced on each side. The inflorescence is a cyme of 2 to 30 flowers which are variable in color and size. Each has usually five petals up to a centimeter long which may be white to pale yellow to gold. Varieti ...

Drymocallis Arguta
''Drymocallis arguta'', commonly known as the tall cinquefoil, prairie cinquefoil, or sticky cinquefoil, is a perennial herbaceous plant native to North America. It was formerly included with the typical cinquefoils in the genus ''Potentilla''. Description The leaves are pinnately compound with an uneven number of leaflets, most commonly 7 to 11. Most leaves are found in a rosette at the base of the plant, but there are some leaves arranged alternately along the flowering stem. Leaves are densely covered in short and somewhat sticky hairs (trichomes). The flowers are arranged in a tight cluster ( cyme) on a long stem from tall. They are strawberry-like, with five white or cream petals, five pointed green sepals between the petals, and a round head of pistils in the center with more than 20 stamens in a ring around it. Nectar is secreted from a ring below the pistils. The flowers are small and the nectar and pollen are easy for short-tongued insects to reach. Small short-tongu ...

Cinquefoil
''Potentilla'' is a genus containing over 300Guillén, A., et al. (2005)Reproductive biology of the Iberian species of ''Potentilla'' L. (Rosaceae).''Anales del Jardín Botánico de Madrid'' 1(62) 9–21. species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae. Potentillas may also be called cinquefoils in English, but they have also been called five fingers and silverweeds. Some species are called tormentils, though this is often used specifically for common tormentil (''P. erecta''). Others are referred to as barren strawberries, which may also refer to '' P. sterilis'' in particular, or to the closely related ''Waldsteinia fragarioides''. Several other cinquefoils formerly included here are now separated in distinct genera - notably the popular garden shrub ''P. fruticosa'', now ''Dasiphora fruticosa''. Potentillas are generally found throughout the northern continents of the world (holarctic), though some occur in montane biomes ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protocarnivorous Plant
A protocarnivorous plant (sometimes also paracarnivorous, subcarnivorous, or borderline carnivore), according to some definitions, traps and kills insects or other animals but lacks the ability to either directly digest or absorb nutrients from its prey like a carnivorous plant. The morphological adaptations such as sticky trichomes or pitfall traps of protocarnivorous plants parallel the trap structures of confirmed carnivorous plants. Some authors prefer the term "protocarnivorous" because it implies that these plants are on the evolutionary path to true carnivory, whereas others oppose the term for the same reason. The same problem arises with "subcarnivorous". Donald Schnell, author of the book ''Carnivorous Plants of the United States and Canada'', prefers the term "paracarnivorous" for a less rigid definition of carnivory that can include many of the possible carnivorous plants.Schnell, 2002 The demarcation between carnivorous and protocarnivorous is blurred by the lack of ...

Jules Pierre Fourreau
Jules Pierre Fourreau (25 August 1844, Lyon – 16 January 1871, Beaune) was a French botanist. As a young man he worked as an assistant to botanist Alexis Jordan (1814-1897) in Lyon. Beginning in the mid-1860s, he began collecting plants throughout southeastern France (Ardèche, the Alps, Provence, et al.). In November 1870 he enlisted in the ''Légionnaires du Rhône'', and on 16 January 1871 he died in a hospital in Beaune as a result of injuries received at the Bataille de Nuits (18 December 1870).Prosopo Sociétés savantes de France In 1864 he became a member of the ''Société linnéenne de Lyon''. In 1867 he introduced the genus name ''Mistralia'' (family ) in honor of poet |
