AUTHOR'S INTRODUCTION. 3 



Lesser Periwinkle, bluish (or white). 



Bugle, bluish (or pinkish or white). 



Spotted Orchis, lilac (or white). 



Wild Roses, rose-pink (or white). 



Thistles, red-purple (or white). 



Hemp-Nettle, pale yellow and purple (or white). 



Herb-Robert, pink (or white). 



Willow-herb, pinkish (or white). 



Cornflower, blue (or dark purple). 



But the ordinary colour in these cases is decided by the 

 colour of the majority amongst which they grow. 



3. According to the average size of the flower, refer to 

 the division in which you may reasonably expect to find 

 it described. In order to do this, measure across the 

 mouth of the flower, taking the greatest diameter as the 

 guide. It is essential to fix on the average size of any 

 particular kind of flower, for sometimes a very large, well- 

 nurtured specimen or a very small starved and stunted 

 one might lead you to assume that such was the usual 

 size of the species. 



The following Scale of Sizes is used throughout : 



Very large flowers, from 2 in. to 4 in. across. 

 Large flowers, from 1 in. to 2 in. across. 

 Medium flowers, from J in. to 1 in. across. 

 Small flowers, from J in. to J in. across. 

 Very small flowers, from J in. to J in. across. 

 Minute flowers, less than J in. across. 



SCALE or INCHES. 



4. Compare the description given with the specimen in 

 hand, taking care to observe not only the flowers, but also 

 the stem, leaves, and other parts of the whole plant. 

 For this purpose a short outline of the general elementary 

 structure of flowers, leaves, and stems, etc., is given in 

 this portion of the book.
