54. The first genus mention- 

 ed is, u HYE;RANGEA ?> this is 

 said to have a "calyx 5 tooth- 

 td, superior," examine thy 

 calyx of the pink (Fig. 5, a;) 

 this is five toothed, or has five 

 notches around the top of it, 

 but it is not superior, that is, 

 the calyx does not stand above 

 the germ. Your flower is not 

 therefore of the genus Hydran- 

 gea, because it does not fully 

 agree with the description. 



55. SAXIFRAGA. "Calyx 5 parted, half superior ;" althojgh 

 the first part of this description agrees with your flower, die 

 last part does not correspond with it. 



56. SApaNARiA. " Calyx inferior" (under the germj " \ 

 leafed" (all of one piece ;) " tubular," (long and hollow like a 

 tube,) "5 toothed;" so far this description applies to your (low- 

 er. But the next circumstance, " calyx without scales" is dif- 

 ferent from what you see in the pink, (See Fig. 5. &.*) 



57. "DIANTHUS. Calyx inferior, cylindrical" (long and 

 roundish ;) " 1 leafed, with 4 or 8 scales at the base ; petals 5," 

 (See Fig. 4. a) " with claws," (the petals long and slender at 

 the lower part;) "capsule" cylindrical, I celled (t?ja capsule 

 is a kind of pericarp ;) " dehiscent" this means gapirg, as you 

 see at Fig. 5. c, which represents the capsule or set A vessel oi 

 the pink as it appears when ripe, the valves or pieces which 

 compose it, open of themselves as if for liberating the seeds. 

 At d the capsule appears as if cut horizontally, showing the 

 seeds all contained in one cell. Fig. 4 at c shows the capsule 

 as it appears when the pink is in blossom, at which time it is 

 called the germ. As this flower agrees in every particular 

 with the last mentioned description, you may be certain you 

 have now found its genus ; the pink then belongs to the genus 



DIANTHUS.
