flowers, each on a stem a few inches high, others 

 are quite branching, while a few are erect in growth, 

 with several flowers in a compact head on the top 

 of stems varying between one foot and two feet high. 



As the species cross readily it naturally follows 

 that natural hybrids are numerous. Nyman, in his 

 enumeration of European plants, mentions thirteen, 

 but this is probably below the right number. Those 

 species mainly responsible for the hybrids are D. 

 deltoides, D. super bus, and D. barbatus. Garden 

 hybrids are numerous, and when several species are 

 grown close together the seedlings are rarely true 

 to name, intermediate forms appearing freely in a 

 batch of seedlings. It therefore follows that it is 

 necessary to increase the plants by cuttings if the 

 species is desired true to character. 



The following list includes most of the more 

 distinct species, some being omitted owing, not to an 

 absence of beauty, but to the slight difference that 

 exists from other forms. The genus may be conveni- 

 ently divided into two great groups, and these may 

 again be divided into two sets. 



GROUP I. With flowers in heads. 



A. Flowers clustered, furnished with numerous 



membraneous or coriaceous bracts. 

 B. Flowers in approximate heads, no bracts of a 

 distinct character from the leaves. 



GROUP II. With scattered or solitary flowers. 

 C. Petals not fringed. 

 D. Petals fringed. 



A. Dianthus arboreus. A shrubby (frutescent) Pink
