The genera of Labiates have been distributed into eight Tribes, of which 
the five following are represented in Britain. 
1. MonarpDEs. Two ascending stamens, in which one cell of each anther is 
either wanting or separated from the other. Genus,—l. Satvia. 
2. SATUREINEH. Two or fourspreading or ascending stamens. Upper lip of the 
corolla with the lobes usually flat. Genera :—2. Lycopus; 3. MrentHa; 4, THYMUS; 
5. ORIGANUM ; and 6. CALAMINTHA. 
3. NEPETER. Four ascending stamens, of which the upper or middle pair are 
the longest (project above the others), while in the preceding and two following 
tribes the lower or outer pair are the longest. Genus,—7. NEPETA. | 
4. STACHYDER. Four ascending stamens. Upper lip of the corolla usually con- 
cave or arched. Genera:—8. PRUNELLA ; 9. ScuTELLARIA; 10, Mexirris; 11. MAR- 
RUBIUM ; 12. StacHys; 13. GALEopsis; 14. " BALLOTA ; 15. LEONURUS ; and 16, Lamium. Z 
5. AJUGOIDER. Stamens ascending (4 in the British genera). Corolla apparently 
1-lipped. Genera -—ly, TEUCEIUM ; and 18. AsuGaA. 
Among Lubiats genera entirely exotic, the sweet Basil (Ocymum), 
Lavender (Lavandula), Rosemary (Rosmarinus), Balm (Melissa), Savory — 
(Satureia), and Hyssop (Hyssopus), are cultivated among our culinary — 
potherbs; several species of Coleus, including the Patchouly, in our hot- — 
houses ; the shrubby Phlomis and Leonotis, and the herbaceous Perillas,
