Rumex kerneri is a species of flowering plant in the knotweed family known by the common name Kerner's dock. [1] It is native to Europe. It has also been observed in California as an introduced species and roadside weed. It is a perennial herb producing a slender, erect stem from a thick taproot, approaching 1.5 meters in maximum height. The lance-shaped leaves can be up to 25 centimeters long and have smooth, wavy, or wrinkly edges. The inflorescence is an interrupted series of clusters of flowers, with 15 or 20 in each cluster, each flower hanging from a pedicel. The flower has usually six tepals, the inner three of which are largest, about 6 millimeters long, edged with tiny teeth and bearing rounded tubercles in the centers.

In biology, a species ( ) is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

Plant multicellular eukaryote of the kingdom Plantae

Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were treated as plants. However, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes. By one definition, plants form the clade Viridiplantae, a group that includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, mosses and the green algae, but excludes the red and brown algae.

Polygonaceae family of plants

The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus Polygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum. The name refers to the many swollen nodes the stems of some species have. It is derived from Greek; poly means many and goni means knee or joint.

This species is sometimes treated as a subspecies of Rumex crispus .
