Classification in the Linnean hierarchy

    Linneaus recognized only five hierarchal categories: Kingdom, Class, Order, Genus & Species. The modern system uses the seven categories shown here (adding Phylum and Family), as well as super- and sub- category prefixes for most of these. Other categories sometimes used include Legion (between Class & Order), Cohort (between Order & Family), and Tribe (between Family & Genus). Additional prefixees can include Magn-, Grand- and Infra- . The categorical level of many names is indicated by certain suffixes, listed below.

    To remember the sequence of categories, recall that "King Philip Came Over For Good Sex."
