63. SAGE OR MINT FAMILY. Order LABIATiE. 

 Herbs with square stems and opposite aromatic leaves, a, 2-lipped (or rather irregular) 

 corolla, 4 stamens in pairs (2 long and 2 shorter), or else only 2 sta- 

 mens, and a 4-parted ovary, in fruit making 4 akenes around the 

 base of the single style. That is, among the families with 2-lipped 

 or irregular monopetalous corollas this is at once known by the 4- 

 lobed ovary, making 4 akenes. The leaves arc commonly more or 

 less dotted wit'.i small glands, which contain a volatile oil, peculiar to 

 each species. This gives the warm aromatic properties which all 

 plants of this family possess. By distillation, the oil is extracted from 

 several species, as from Peppermint and Spearmint, Lavender, Pen- 

 nyroyal, &c. Or the dried foliage is used for seasoning or for herb 

 drinks in the case of Summer- Savory, INIarjoram, Thyme, Catnip, 

 and Sage. The following are the common genera or kinds of this 

 large family.
