Natural Order LIX 



LABIATE. Labiate Tribe 



Calyx tubular, regular, or 2-lipped ; corolla irregular, mostly 

 2-lipped (labiate), the lower lip largest and 3-lobed ; stamens 4, 

 2 longer than the others, 01 sometimes wanting ; ovary deeply 

 4-lobed ; style 1 ; stigma 2-cleft ; fruit of 4 seeds, each of which 

 is enclosed within a distinct shell or rind. A large and strongly- 

 marked Natural Order, comprising some 2500 species of herbs and 

 shrubs, which all agree in having square stems, opposite leaves, 

 labiate, or 2-lipped flowers, and a 4-lobed ovary with a single style 

 arising from the base of the lobes. They are most abundant in 

 temperate climates, and are remarkable for not possessing injurious 

 properties in any single instance. Many are fragrant and aromatic. 

 Patchouli is a favourite perfume, both in its natural state and when 

 distilled. Lavender contains a fragrant volatile oil, which is valued 

 both for its fragrance, and as a medicine for its stimulant proper-
