Families and Genera of Spermatophytes Recognized by the Agricultural ResearchService

摘要

The report includes the correct scientific names and authors for families andgenera of spermatophytes of the world required by U.S. Department of Agriculture personnel and other agricultural scientists. Of the 1,207 family names listed, 399 are accepted, and the remainder are placed in synonymy. For the first time the Agricultural Research Service has made taxonomic and nomenclatural decisions concerning more than 13,500 recognized generic names, excluding hybrids, which are grouped by family and presented both by family and in alphabetical order. All previously published generic lists were alphabetical, thus obscuring the generic composition of a family.
