24 BRITISH WILD FLOWERS 



There are many plants among the rose family 

 (Group xvii) which look very much like butter- 

 cups (Group xviii) ; but if we study the 

 explanations attached to these two groups, we 

 shall at once see how widely they differ. We 

 ought here specially to note the following : 



COMPOSITES (Group viii). Example: Daisy. 

 Plants whose flowers are compound. Each of 

 the perfect flowers has five stamens, the anthers 

 of which form a tube. See Horse Daisy, 

 Fig. 19. 



LABIATES (Group iv). Example : Mint. 

 Flowers lip-shaped, four stamens, and four seeds 

 or nutlets in an open receptacle. 



LEGUMES (Group xv). Example : Pea. 

 Flowers butterfly -shaped, stamens ten, seeds 

 usually in pods. A few plants, such as fumitory 

 and the little blue milkwort, the butterwort and 

 bladderwort, somewhat resemble labiates and 

 legumes, as do also some of the Broomrapes 

 and Scrophulariaceae (Group iv), Fig. 24. 



CRUCIFERS (Group x). Example : Wall- 

 flower. There are four petals and six stamens. 

 They can easily be distinguished from other 

 plants with six stamens (Group ix) by the 

 number of petals and the shapes of the leaves 



(Fig. 22). 



UMBELS (Group vi). Example : Carrot. 

 Flowers spreading like an umbrella, nearly 

 always white.
