Fruit: generally 4 nutlets, generally ovoid to oblong, smooth.
Genera In Family: +- 230 genera, 7200 species: worldwide. Many cultivated for herbs, oils (Lavandula, lavender; Mentha, mint; Rosmarinus, rosemary; Thymus, thyme), some cultivated as ornamental (in California Cedronella, Leonotis, Monarda, Phlomis). Note: Moluccella laevis L., shell flower, historical waif in California. Satureja calamintha (L.) Scheele subsp. ascendens (Jordan) Briq. reported as alien but not naturalized.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
