The family has a
cosmopolitan distribution.[4] The enlarged Lamiaceae contain about 236
genera[5] and have been stated to contain 6,900[4] to 7,200[5]species, but the World Checklist lists 7,534.[6] The largest genera are Salvia (900), Scutellaria (360), Stachys (300), Plectranthus (300), Hyptis (280), Teucrium (250), Vitex (250), Thymus (220), and Nepeta (200).[5]Clerodendrum was once a genus of over 400 species,[5] but by 2010, it had been narrowed to about 150.[7]
The alternative family name Labiatae refers to the flowers typically having petals fused into an upper lip and a lower lip (labia in Latin). The
flowers are bilaterally symmetrical with five united
petals and five united
sepals. They are usually
bisexual and verticillastrate (a flower cluster that looks like a whorl of flowers, but actually consists of two crowded clusters). Although this is still considered an acceptable alternative name, most botanists now use the name Lamiaceae in referring to this family. The
leaves emerge oppositely, each pair at right angles to the previous one (decussate) or whorled. The stems are frequently square in cross section,[10] but this is not found in all members of the family, and is sometimes found in other plant families.
Genera
The last revision of the entire family was published in 2004.[5] It described and provided
keys to 236 genera. These are marked with an asterisk (*) in the list below. A few genera have been established or resurrected since 2004. These are marked with a plus sign (+). Other genera have been synonymised. These are marked with a minus sign (-). The remaining genera in the list are mostly of historical interest only and are from a source that includes such genera without explanation.[11] Few of these are recognized in modern treatments of the family.
The
circumscription of several genera has changed since 2004. Tsoongia, Paravitex, and Viticipremna have been sunk into
synonymy with Vitex.[15]Huxleya has been sunk into Volkameria.[7]Kalaharia, Volkameria, Ovieda, and Tetraclea have been
segregated from a formerly
polyphyleticClerodendrum.[7]Rydingia has been separated from Leucas.[16] The remaining Leucas is
paraphyletic over four other genera.[17]
