 OKD. Caryopnyllete. Tufted, mostly glaucous herbs, often

 five, entire or cut, with long claws. 

 Leaves narrow, grass-like. This genus con- 

 sists of about seventy species, according 

 ,^KjI to the authors of the " Genera Plantarum," 

 although more than four times that nnm- 

 ^^M ber have been accorded specific rank by 

 ^^^f various botanists. Just a hundred are re- 



^f garded as species by Nyman, in his 



enumeration of European plants. The 

 list given below includes only such as are 

 known to be in cultivation. In most cases, 

 the specific distinctions are very trivial, 

 and this fact has also necessitated several 

 omissions. Hardy perennials, except 

 where otherwise specified. For culture, tee Carnation 

 and Pink.
