The 10th edition of Systema Naturae is a book written by Swedish naturalist Carolus Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of Species Plantarum.Pectis
Pectis is a genus of flowering plants in the daisy family, Asteraceae described as a genus by Linnaeus in 1759.The name is derived from the Latin word pecten, meaning "comb." It refers to the marginally-bristled leaves or the pappus form. These plants vary in appearance but they usually bear yellow daisy-like flower heads. Members of the genus are known generally as cinchweeds (current usage) or chinchweeds (older name).They are native to the Americas, including the West Indies.
