SPECIES OF DIANTHUS 7 



D. glacialis. A native of the mountains of South- 

 Eastern France, and a very difficult plant to cultivate, 

 continual wetness at root being essential to its health. 

 It was introduced in 1820. A supposed hybrid between 

 the above and D. alpinus is usually cultivated in gardens 

 as D. glacialis. It flowers in April, and is a desirable 

 species. 



D. hispanicus is a very slender-stemmed species, with 

 deep crimson flowers an inch and a half across. 



D. Holtzeri. A species from Turkestan that seems to 

 possess many characteristics of D. superbus y but with 

 darker flowers. 



D. Knappi. A late introduction, growing nine inches 

 in height, possessed of flowers of a clear pale yellow, and 

 partaking of the character of D. liburnicus. 



D. latifolius. Much like D. barbatus, but larger both 

 in flower and foliage. It is figured in Sweet's u British 

 Flower Garden." 



D. liburnicus. A strong-growing plant, producing its 

 red flowers in heads. Leaves and stems are glaucous, 

 hence one of its names is D. glaucophyllus, and it is not 

 uncommonly cultivated as D. Balbisii. 



D. monspessulanus. A good border variety, introduced 

 in 1764. The flowers are red with petals much 

 laciniated. 



D. neglectus. One of the D. alpinus group, but more 

 beautiful than that species, with foliage somewhat like 

 that of D. c&sius. The underside of the petals are 

 greenish-blue. It blooms earlier in the year than D. 

 alpinuSy and sometimes succeeds where the last-named 

 fails. It grows on the Mont Cenis Alps, and was intro- 

 duced in 1869. Treat as D. alpinus. D. neglectus a /bus 

 is a rare white form. 



D. pallidiflorus. A showy pale-flowered species from 

 Siberia. It is late flowering, and is suitable for the rockery. 

 D. pallens is a synonym.
