THE PINKS OF THE ALPS 135 



D. deltoides (L.). A many - stemmed, extremely 

 turfy plant, forming large tufts of bright, shining 

 foliage that in itself is ornamental. The flowers 

 of moderate or rather small size, and of a bright 

 rosy-carmine colour, are on branched stems from 

 4 to 10 inches high ; they are extremely numerous, 

 and appear from June to late autumn. At the 

 throat they have dark purple spots of delta form, 

 hence the specific name. There is a variety with 

 white flowers in which the spots are of a very dark 

 colour, and another with bluish, glaucous leaves. 



It is very easy to grow. Whether in sun or in 

 half-shade it succeeds nearly everywhere, flowering 

 with remarkable abundance. It can not only be 

 used as an edging and in ornamental rock-work, 

 but actually as a turf, and it is an admirable plant 

 for clothing dry and arid slopes. It is found wild 

 throughout a large part of Europe and temperate 

 Asia. 



D. Falconeri (Edgew.). A small plant with ex- 

 tremely glaucous foliage, almost blue, with rambling 

 shoots and small yellowish-white flowers that appear 

 in May and June. We have had the seed from 

 Mr. Duthie, Director of the Saharanpur Botanical 

 Garden, marked provisionally as " Dianthus sp. 

 Hazara" It was identified for us by Dr. F. N. 

 Williams, but it does not quite correspond with 

 Edgeworth's description, 1 and Dr. Williams thinks 

 that it is a new species not yet described. 



D. fragrans (Bieb.'). A Caucasian plant, very rare
