740. MINT FAMILY. LAMIACEAE. 



An immense family of aromatic herbs (shrubs and trees 

 in the tropics) with simple, opposite leaves, and nearly always 

 a square stem. Flowers irregular and unsymmetrical, in those 

 below, mostly 2-lipped, arranged in various kinds of clusters, 

 most commonly in rather dense ones, often in terminal spikes 

 or racemes. Corolla with a short or long tube, 3 of its lobes 

 larger than the other two. The fruit consists of four i -seeded 

 nutlets, enclosed by the remains of the flower. Common ex- 

 amples are savory, lavender, and many old-fashioned garden 

 herbs. All of them are difficult to identify without the use of 

 technical characters, and for this reason illustrations will 

 be given for all included here. For other plants of the family 

 see Nos. 713-720.
