SPECIES OF D1ANTHUS 3 



is derived. From the botanist's point of view introduced 

 in 1573, but an English garden plant previous to that 

 date. 



D. bicolor. This species is so named on account of the 

 undersides of the petal being leaden-coloured, the upper 

 portion being white. The plant was brought from 

 Tauria, in South Russia, in 1816, and grows to a height 

 of one foot or more. 



D. crtsius is our English representative of the Alpine 

 species. It is found only on limestone rocks at Cheddar, 

 in Somersetshire, hence called the Cheddar Pink, and on 

 old walls near Oxford, the flowers of the Oxford variety 

 being somewhat larger than the Cheddar form, and is 

 known as the Oxford Pink. There is a still larger 

 flowered variety called D. c. grandiflorus, but the colour is 

 not so deep a rose as in flowers of the others. In Ray's 

 " Synopsis," the species is said to have been found growing 

 in the North of England, as well as on " Chidderoks." 

 It is not difficult to cultivate, and, even when flowerless, 

 the plant, on account of its densely glaucous-grey foliage 

 whence its name, " Caesius " is an object of interest. 

 As a pot plant, if plenty of lime rubbish is mixed in the 

 compost, it succeeds well ; and it is, indeed, a commend- 

 able practice when introducing plants to a rockery to estab- 

 lish them previously in pots. The plant abhors moisture 

 clinging about the foliage and stems ; an ideal situation 

 being on the face of a stone or an old wall. We find it 

 first designated the " Mountain Pink," and on account 

 of the colour of its foliage Miller named it D. glaucus. 

 The Cliff Pink is another of its common names. 



D. callizonus is a somewhat late introduction from 

 Transylvania, and flowered first at Kew about the year 

 1890. The flowers are much larger than those of 

 D. alpinus, brightest rose in colour, or rosy purple, with 

 a zone of deep crimson surrounding the centre, which 

 is whitish. The habit of the plant partakes more of that
