The specimens are classified according to biological nomenclature. Thus each unique name traces to an original description, published over the past 250 years. The earliest valid names trace to the seminal works of Linnaeus. The vast majority of names originated with the 19th century exploration of the American West. However, new species continue to be discovered and described today. Any research into the application of biological nomenclature requires an evaluation of the original description. Our ultimate goal is to make available digitized original descriptions of all 4500 plant taxa (species, subspecies and varieties) in the Oregon flora.
