drupaceous, with fleshy or thick epicarp and hard endocarp. Stenogyne, 

 Go,npho.,em.„a .nd Prasium. | 



IV. Scutellarioideae 



Style gynobasic; fruit consisting of nutlets with basic placentation, dry, 

 with seeds lying more or less transversely. Scutellaria, Salazaria. 



V. Lavanduloideae 



Style gynobasic; stamens four, unilocular at the tips, fruit consisting 

 of dry nutlets with erect seeds and embryos with short, straight, superior 

 radicles. Only genus Lavandula. 



VI. Stachydoideae 



Style gynobasic; stamens ascending or spreading and projecting 

 straight forward; fruit consisting of nutlets with small basal attachments. 



This sub-family is divided into twelve tribes of which we may mention 

 the following which are represented in the British Flora. 



1. Marnihieae. Sepals united; calyx bilabiate with entire lip. Corolla 



bilabiate or almost actinomorphic. Stamens four or two. 

 Marruhium. 



2. Nepeteae. Sepals united, tube fifteen-ribbed. Corolla bilabiate. 



Stamens four, the posterior pair larger or sometimes the only ones 

 developed. Nepeta. 



3. Stachyeae. Sepals united, calyx tube five- to ten-ribbed. Upper 



lip of corolla concave or helmet-shaped. Stamens four, lying 

 parallel to one another under the upper lip. Prunella, Galeopsts, 

 Melittis, Lamiuni, Ballota, Stachys. 



4. Salvieae. Sepals united, calyx campanulate or tubular. Corolla 



bilabiate with sickle-shaped or helmet-shaped upper lip. Only 

 the two anterior stamens fertile. Salvia. 



5. Saturejeae. Calyx generally five-toothed, sometimes bilabiate. 



Corolla with flat lobes, either actinomorphic or bilabiate. 

 Stamens four to two, equal in length, or the anterior ones 

 longer. Calamintha, Origanum, Thynuis, Mentha, Lycopus. 



VII. Ocimoideae 



Style gynobasic. Stamens descending and lying upon the lower lobe 

 of the corolla or enclosed by it. Fruit consisting of nutlets with short 

 basal attachment. Hyptis, Ocimum. 



VIII. Catopherioideae 



Style gynobasic; fruit consisting of dry nutlets; seeds erect. Catopheria. 



The Ajugoideae include several common British genera. Ajiiga contains 

 some thirty species distributed through temperate regions, three of which 

 are found in Britain, A. reptans (Bugle) and A. chamaepitys (Ground 

 Pine) being the more common. Cleistogamic flowers have been described 

 in Ajuga but are not common. In the genus Teucrium there are about 100 

 cosmopolitan species, four of which are found in the British Isles. T.
