(Mint Family) 



Chiefly herbs, ordinarily with square stems, opposite aromatic leaves, more o» 

 less 2-lipped corolla, didynamous stamens or these only two, and a deeply i-lobed 

 ovary, which forms in fruit 4 little seed-like nutlets or achenes, surrounding the 

 base of the single style in the bottom of the persistent calyx, each filled with a 

 single erect seed. Nutlets smooth or barely roughish and fixed by their base, 

 except in the first tribe. Albumen mostly none. Embryo straight (except in 

 Scutellaria) \ radicle at the base of the fruit. Upper lip of the corolla 2-lobed 

 or sometimes entire ; the lower 3-lobed. Stamens inserted on the tube of tlie 

 corolla. Style 2-lobed at the apex. Flowers axillary, chiefly in cymose clusters, 

 these often aggregated in terminal spikes or racemes. — Foliage mostly dotted 

 with small glands containing a volatile oil, upon which depends the warmth and 

 aroma of the plants of this large and well known family. 



I. Nutlets rugose-reticulated, attached obliquely or ventrally ; ovary merely 



4-lobed. 



Tribe I. AjtTGEAB. Stamens 4, ascending and parallel, mostlv exserted f^om the upper side oi 

 the corolla. Oalyx 6-10-nerved. 



* Limb of corolla irregalar, eeemtng-ly unilablate, the upper lip being either split down or very 

 short ; stamens exserted from the cleft. 



1. Ajuga. Corolla with a very short and as If truncate upper lip. 



2, Teucrium. Corolladeeply cleft between the 2 smsD lobes of the upper lip.
