Whole plant often covered with vesicular glands containing an odoriferous 

 volatile oil. STEM herbaceous or sub-woody, rarely woody, usually 4-gonous. 

 LEAVES opposite or whorled, with pinnate reticulate nerves, exstipulate. FLOWERS 

 $ , irregular, very rarely sub-regular (Mentha], in the axils of leaves or bracts, soli- 

 tary or geminate, or in clustered centrifugal cymes, which form false whorls by their 

 union in pairs, and are scattered, or crowded into spikes, CALYX persistent, of 

 5 connate sepals, sometimes irregular, 2-lipped, upper lip 2-fid, lower 3-fid, sometimes 

 sub-regular with 5 segments, or 4 by the arrest of the upper. COROLLA moiiopetalous, 

 hypogynous; lube sometimes twisted (Hyssopus lophantus, Ajuga orientalis) ; limb 

 4-5-lobed, sestivation imbricate, sometimes 2-labiate, the upper lip entire or emargi- 

 nate, the lower 3-lobed, sometimes 1-labiate from the upper lip being very short and 

 deeply cleft (Ajuga}, sometimes being bell- or funnel-shaped with 4 sub-equal lobes 

 and sub-equal stamens (Mentha). STAMENS inserted on the corolla- tube, usually 4, 

 didynamous, rarely 2 by arrest of the 2 upper (Cunila, Lycopus, Salvia, Rosmarinus) ; 

 anther-cells often confluent at the top, sometimes separated by a well-developed 

 filiform connective (Salvia). OVARY free, of 2 carpels, borne on a thick disk, with 4 

 lobes or cells, all free or cohering in pairs ; style simple, rising from the base of the 

 ovarian lobes, and dilating into a gynobase which lines the disk ; stigma generally 

 bifid ; ovules solitary and erect in each cell, anatropous. FRUIT of 4 achene-like 

 lobes or nucules, free or geminate, epicarp sometimes fleshy (Prasium). SEEDS erect.
