The genera of Labiates have been distributed into eight Tribes, of 

 which the five following are represented in Britain. 



1. MONARDE.B. Two ascending stamens, in which one cell of each anther la either 

 wanting or separated from the other. Genus 1. SALVIA. 



2. SATOREINE.E. Two or four spreading or ascending stamens. Upper lip of the 

 corolla with the lobes usually flat Genera : 2. LYCOPUS ; 3. MENTHA ; 4. THYMUS ; 

 5. ORIGANUM ; and 6. CALAMINTHA. 



8. NEPKTBJ5. 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. STACHYDEJE. Four ascending stamens. Upper lip of the corolla usually con- 

 cave or arched. Genera: -8. PRUNELLA; 9. SCUTELLARIA; 10. MEUTTIS; 11. II AR 

 RUBIUM ; 12. STACHUS ; 13. GALEOPSIS ; 14. BALLOTA ; 15. LEONURUS ; and 16. LAMIUM. 



6. AJUOOIDB.S. Stamens ascending (4 in the British genera). Corolla apparently 

 1-lipped. Genera: 17. TEDORIUM; and 18. AJUOA. 



Among Labiate genera entirely exotic, the tweet Basil (Ocymum), 

 Lavender (Lavanduta), Rosemary (Sosmarinus), 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 PerUlat, 

 Monardat, and Dracocephalums, and others, in our flower-gardens. 



I. SALVIA. SAGE. 



Herbs, or, in some exotic species, shrubs, with the flowers usually 

 in whorls of 6 or more, forming terminal racemes or spikes, the floral 

 leaves all or most of them reduced to mere bracts. Calyx 2-lipped, 

 the upper lip entire or with 3 small teeth, the lower one 2-cleft. 

 Corolla with the upper lip erect, concave, or arched; the lower 

 spreading, 3-lobed; the middle lobe often notched or divided. 

 Stamens really 2, although easily mistaken for 4, for the anthers 

 have a long slender connective, having the appearance of a fila- 

 ment, fastened by the centre to the very short real filament, and 

 bearing at one end a perfect anther-cell under the upper lip of the 

 corolla, and at the other end a small cell, almost always empty, and 

 usually much deformed. 



A very large genus, widely spread over the temperate and warmer 

 regions of the globe, although within the tropics the majority of 

 species are mountain plants. The structure of the stamens readily 

 distinguishes them from all other Labiatas. 



Leaves mostly radical. Corolla large, near thrice as long as the 



calyx] 1. S. pratengit. 



Stem leafy. Corolla imall, not twice the length of the calyx . . S. Verbenaca. 



Many exotic species are cultivated in our gardens, the Common or 

 garden Sage (S. o/icinalis} from southern Europe, as a potherb, and 

 ceveral American ones for the beauty of their flowers.
