302 XCVI. LABIATiE. 



axils of the upper leaves, or capitate, or in branched cymes, 

 rarely solitary. Natives p^enerally of the drier and warmer 

 parts of the globe, very many of them aromatic ; some, as the 

 Mints, Thyme, Lavender, Patchouli, etc., eminently so. This 

 large Order, which is very imperfectly represented in South 

 Africa, is arranged by Bentham under 8 tribes, including 120 

 genera. 



Tribe 1. Ocime^. Stamens declinate. 



* Corolla-lobes of nearly equal length, the 4 upper 

 more or less connate in an u^iper lip, the lowest 

 narrower, declinate, flat or subconcave. 

 Fruiting-calyx deilexed, the upper tooth very 



large, ovate, decurrent on the tube 1. Ocimum:. 



Fruit-calyx declined, 5-toothed, the upper tooth 

 ovate, not decurrent ; corolla-tube short, in- 

 cluded 2. MOSCHOSMA. 



Fruit-calyx suberect, with 5 subequal teeth ; co- 

 rolla-tube long, exserted 3. Syncolostemon. 



•* Lowest lobe of the corolla elongate, concave. 



Upper stamens abortive ; fruit-calyx fleshy . . 4. Hoslundia. 

 All the stamens fertile. 



Fruit calyx toothed, the teeth not spiny, mouth 



open , . . 5. Plectranthtis. 



Fruit-calyx truncate, circumcissed at base . . 6. ^olanthus. 

 Fruit-calyx with 5 equal, spinous teeth ... 7. PycnostaCHYS. 

 *** Lowest lobe of corolla conti'acted at base, then 

 saccate, abruptly deflexed ; calyx sharply 

 5-toothed 8. Htptis. 



Tribe 2. Satureink^. Stamens distant, straight, spreading, or ap- 

 proaching under the upper lip of corolla ; anthers 2-celled ; lobes of corolla 

 fiat. 



Corolla subequally 4-lobed ; stamens 4, equal ... 9. Mentha. 

 Corolla 2-labiate, upper lip erect, subentire, lower 3- 



lobed, spreading ; stamens 4, didynamous . . .10. MiCROMERiA. 



Tribe 3. Monarde^. Stamens 2, straight or ascending ; anthers either 

 1-celled, or of 2 cells separated by a filiform connective. 



Stamens 2, in the throat ; anthers with a long, fili- 

 form connective, bearing a fertile cell at its upper 

 end 11. Salvia. 



Tribe 4. Stachtde;E. Stamens 4, parallelly ascending under the 

 vaulted or subconcave upper hp of corolla. 



Stamens included ; anthers 1-celled ; style bearded 



below the apex 12. AcROTOME. 



Stamens exserted ; anthers 2-celled ; style nude. 

 Style subequally 2-fid, the lobes subulate. 



Calyx subequally 5-toothed or -fid 13. Stachys. 



Calyx wider upwards, with 5 large and 5-10 



smaller spreading teeth 14. Ballota. 



Style unequally 2-fid, one lobe very short ; corolla 

 very hairy.
