シソ科 (Lamiaceae) はシソ目に属する植物の科の一つ。
シソのほか、バジル、ミント、ローズマリー、ラベンダー、セージ、マジョラム、オレガノ、タイム、レモンバームなど多くのハーブを含むほか、サルビア、ムラサキシキブ、アジュガなど非芳香性の品種も園芸品種として栽培される。低木やつる性の種もある。
シソ科の植物には抗変異原性があるものが多い[1]。
葉は対生で、精油を含むため香気に富むものが多い。茎の断面は正方形のものが多い。花は左右相称で5枚の花弁(合弁)と萼がある。普通、両性花をつける。果実は4個に分かれ種子を1個ずつ含む。
シソ科は大きく重要な科であるため、その特徴として花弁の形が唇状であることから、新エングラー体系までは学名としてLabiataeが用いられ、昭和中期までその訳語として唇形科(しんけいか)または「くちびるばな科」がもちいられていた。APG植物分類体系では、すべての植物の科名が、典型属に由来するものに改められ、シソ科もオドリコソウ属Lamiumに由来するLamiaceaeに改められた。
しかし長年使われてきたLabiataeを廃止すると混乱が起きるため、保留名として旧名が認められており、最新の書籍でも保留名と新名が併記されていることが多い。
約250属7000種を含む。7つの亜科と、それに含まれない幾つかのクレードから構成される[2]。
次のような系統樹が得られている[2]。

The Lamiaceae (/ˌleɪmiˈeɪsiˌaɪ/[3] or /ˌleɪmiˈeɪsiiː/[3]) or Labiatae (the mint or deadnettle family) are a family of flowering plants. They have traditionally been considered closely related to Verbenaceae,;[4] in the 1990s, phylogenetic studies suggested that many genera classified in Verbenaceae should be classified in the Lamiaceae [5][6] or to other families in the order Lamiales.[1]
The family has a cosmopolitan distribution.[7] The enlarged Lamiaceae contains about 236 genera[4] and has been stated to contain 6,900[7] to 7,200[4] species, but the World Checklist lists 7,534.[8] The largest genera are Salvia (900), Scutellaria (360), Stachys (300), Plectranthus (300), Hyptis (280), Teucrium (250), Vitex (250), Thymus (220), and Nepeta (200).[4] Clerodendrum was once a genus of over 400 species,[4] but by 2010, it had been narrowed to about 150.[9]
The plants are frequently aromatic in all parts and include many widely used culinary herbs, such as basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla. Some are shrubs, trees (such as teak), or, rarely, vines. Many members of the family are widely cultivated, owing not only to their aromatic qualities but also their ease of cultivation: these plants are among the easiest plants to propagate by stem cuttings.[citation needed] Besides those grown for their edible leaves, some are grown for decorative foliage, such as coleus. Others are grown for seed, such as Salvia hispanica (chia), or for their edible tubers, such as Plectranthus edulis, Plectranthus esculentus, Plectranthus rotundifolius, and Stachys affinis (Chinese artichoke).
The original family name is Labiatae, so given because the flowers typically have petals fused into an upper lip and a lower lip (labia in Latin). The flowers are bilaterally symmetrical with 5 united petals, 5 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 (called decussate) or whorled. The stems are frequently square in cross section, but this is not found in all members of the family, and is sometimes found in other plant families.
The last revision of the entire family was published in 2004.[4] 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. The remaining genera in the list are mostly of historical interest only and are from a source that includes such genera without explanation.[10] Few of these are recognized in modern treatments of the family.
Kew Gardens provides a list of genera that includes additional information.[11] A list at the Angiosperm Phylogeny Website is frequently updated.[12]

The circumscription of several genera has changed since 2004. Tsoongia, Paravitex, and Viticipremna have been sunk into synonymy with Vitex.[13] Huxleya has been sunk into Volkameria.[9] Kalaharia, Volkameria, Ovieda, and Tetraclea have been segregated from a formerly polyphyletic Clerodendrum.[9] Rydingia has been separated from Leucas.[14] The remaining Leucas is paraphyletic over four other genera.[15]
In 2004, Lamiaceae were divided into seven subfamilies with ten genera not placed in any of the subfamilies.[4] The unplaced genera are: Tectona, Callicarpa, Hymenopyramis, Petraeovitex, Peronema, Garrettia, Cymaria, Acrymia, Holocheila, and Ombrocharis. The subfamilies are Symphorematoideae, Viticoideae, Ajugoideae, Prostantheroideae, Nepetoideae, Scutellarioideae, and Lamioideae. The subfamily Viticoideae is probably not monophyletic.[13] Prostantheroideae and Nepetoideae are divided into tribes. These are shown in the phylogenetic tree below.
Most of the genera of Lamiaceae have never been sampled for DNA for molecular phylogenetic studies. Most of those that have been are included in the following phylogenetic tree. The phylogeny depicted below is based on seven different sources.[4][6][9][13][16][17][18]
