Compound genus names obtain their gender from the gender of their last component [Rule 65 (2)]. Many genus name were formed by adding a prefix to the name of an already proposed other genus name. The prefix may point to the similarity to or the difference from the other genus. A list of genus names formed in that manner is provided below. Names formed from other genus names by modifying their ending are not listed here. See also the LPSN introductory page on forming names.
