ANALYSIS OF THE PINK. 



23 



w * * * HYDRANGEA. Calyx 5 tooth- 

 id, superior ;" your calyx is 5 

 toothed, (see the notches around 

 the top of it, at Fig. 5, a ;) but it 

 is not superior, that is, it does 

 not stand upon the germ. You 

 must go to the next genus. 



" SAXIFRAGA. Calix 5 part- 

 ed, half superior," but your ca- 

 lyx is not half superior, or part- , 

 ly above the germ. You must 

 go to the next genus. 



" SAPONARIA. Calyx inferi- 

 or, (under the germ ;) 1 leafed, (all of one piece ;) tubular, (long 

 and hollow like a tube ;) 5 toothed," so far the description 

 agrees with the Pink ; next, calyx without scales, (see fig. 5,.) 

 In this particular, your flower, the calyx of which has scales, 

 does not correspond with the description, therefore you must 

 go to the next genus. 



DIANTHUS. Calyx inferior, cylindrical, (much the same as 

 tubular ;) I leafed, with four or eight scales at the base ; petals 

 fve, Fig. 4, a, with claws, (long and slender at the base ;) cap- 

 sule cylindrical, 1 celled, (having no partings ;) dehiscent, (open- 

 ing at the top.) Fig. 5, at c, represents the capsule of the pink 

 as it appears in a mature state, the valves or pieces which 

 compose it, opening spontaneously, as if for liberating the seed ; 

 at d, the capsule appears cut horizontally, showing but one cell, 

 which contains many seeds. Fig. 4, at c, represents the germ, 

 as seen when the pink is in blossom. Your flower agreeing 

 with every particular in the description of the last mentioned 

 genus, you may be certain that you have found the generic or 

 family name of the Pink, which is DIANTHUS. 



But there are several individuals or species in this family ; 

 you wish to know to which species of Dianthus the Pink be- 

 longs ; and this process constitutes a fourth step in your anal- 

 ysis. 



Turn to the Alphabetical Arrangement of Genera,* where the 

 species of each Genus are described, and look for Dianthus. 

 Now compare the description of each species, with a natural 

 flower; " Armeria, flowers aggregate" (in a thick cluster;) 

 this does not agree ; you must look further. 



* This follows the Description of Genera.
