LABI At AE (Mint Family) 



Chiefly herbs, ordinarily with square stems, opposite aromatic leaves, more or 

 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 the 

 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. AjtlGEAE. Stamens 4, ascending and parallel, mostly exserted from the upper side of 



the corolla. Calyx 5-10-nerved. 

 * Limb of corolla irregular, seemingly unilabiate, 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. Corolla deeply cleft between the 2 small lobes of the upper lip.
