According to Art 3.1 of the '' ICBN '' the most important ranks of taxa are: kingdom, '''division''' or '''phylum''', '''class''', '''order''', '''family''', '''genus''', and '''species'''. According to Art 4.1 the secondary ranks of taxa are '''tribe''', '''section''', '''series''', '''variety''' and '''form'''. There is an indeterminate number of ranks. The ''ICBN'' explicitly mentions: ''primary ranks'' - - - ''secondary ranks'' - - - - - - - ''further ranks'' ''kingdom'' (''regnum'') - - - - - - - ''subregnum'' ''division'' or '''phylum''' (''divisio'', ''phylum'') - - - - - - - ''subdivisio'' or ''subphylum'' ''class'' (''classis'') - - - - - - - ''subclassis'' ''order'' (''ordo'') - - - - - - - ''subordo'' ''family'' (''familia'') - - - - - - - ''subfamilia'' - - - tribe (''tribus'') - - - - - - - ''subtribus'' ''genus'' (''genus'') - - - section (''sectio'') - - - - - - - ''subsectio'' - - - series (''series'') - - - - - - - ''subseries'' ''species'' (''species'') - - - - - - - ''subspecies'' - - - variety (''varietas'') - - - - - - - ''subvarietas'' - - - form (''forma'') - - - - - - - ''subforma'' The rules in the ''ICBN'' apply primarily to the ranks of family and below, and only to some extent to those above the rank of family. Also see Descriptive Botanical Names . Taxa at the rank of genus and above get a Botanical Name in one part (unitary name); those at the rank of species and above (but below genus) get a botanical name in two parts ( Binary Name ); all taxa below the rank of species get a botanical name in three parts ( Ternary Name ). For hybrids, getting a Hybrid Name , the same ranks apply, preceded by "notho", with nothogenus as the highest permitted rank. SEE ALSO |
