The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush. Types of placer deposits include alluvium, eluvium, beach placers, aeolian placers and paleo-placers. [2]
Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are ...
This is a list of plants organized by their common names. However, the common names of plants often vary from region to region, which is why most plant encyclopedias refer to plants using their scientific names , in other words using binomials or "Latin" names.

Since the first printing of Carl Linnaeus's Species Plantarum in 1753, plants have been assigned one epithet or name for their species and one name for their genus, a grouping of related species. [1] Many of these plants are listed in Stearn's Dictionary of Plant Names for Gardeners.
Since the first printing of Carl Linnaeus's Species Plantarum in 1753, plants have been assigned one epithet or name for their species and one name for their genus, a grouping of related species. [1] These scientific names have been catalogued in a variety of works, including Stearn's Dictionary of Plant Names for Gardeners.

This list of longest species names lists the longest scientific binomials. [1] Species in this list are grouped by length of their name. Only binomials are considered, not subgenera, trinomial names of subspecies or infraspecific names. Family is given for each species (or the closest taxonomic rank if family is unassigned), with a short ...
