Potentilla arguta arguta |
Potentilla arguta, commonly known as the tall cinquefoil, is a perennial plant in the Rosaceae family of flowering plants native to North America. Frederick Traugott Pursh (or Friedrich Traugott Pursch ( 1774 - 11 July 1820) was a German - American Botanist. In Zoology, as in other branches of Biology, subspecies is the Taxonomic rank immediately subordinate to a Species. A perennial plant or perennial ( Latin per, "through" annus, "year" is a Plant that lives for more than The Rosaceae or Rose family is a large family of Plants with about 3000-4000 species in 100-160 genera The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group There are two accepted subspecies: Potentilla arguta arguta and Potentilla arguta convallaria, which is known as the cream cinquefoil. In Zoology, as in other branches of Biology, subspecies is the Taxonomic rank immediately subordinate to a Species. [1] It is thought to be a protocarnivorous plant. A protocarnivorous plant (sometimes also paracarnivorous, subcarnivorous, or borderline carnivore) according to some definitions traps and kills In his 1999 journal article, G. G. Spoomer tested several plants in the Pacific Northwest for the carnivorous syndrome, using the digestion of proteins as the diagnostic tool to determine which plants appeared to produce protease enzymes capable of breaking down potential prey. The Pacific Northwest is a region in the northwest of North America (the term refers to the land not the ocean Carnivorous plants (sometimes called insectivorous plants) are Plants that derive some or most of their Nutrients (but not Energy) from trapping A protease is any Enzyme that conducts Proteolysis, that is begins protein Catabolism by Hydrolysis of the Peptide bonds that link Potentilla arguta displayed a capability to digest and absorb the 14C-labeled algal protein placed on the sticky trichomes that the plant possesses. However, it is not known whether the digestive enzymes were produced by the plant itself or surface microbes. [2] Additionally, some definitions of carnivory require the plant to gain some tangible benefit in capturing and digesting prey, such as increased seed yield or growth. Such an experiment has not been done with this species.
