Spot-bound, sympodial hemicryptophyte of the semi- 

 rosette type; like the foregoing closely related species, it has 

 a thick, scantily branched main root of long duration; ad- 

 ventitious roots are probably, as a rule, only slightly deve- 

 loped. As P. hirsiita, this species can form large and dense 

 tufts. 



It appears that the first vegetative-stage may be con- 

 fmed to two years, so that the main axis of the young plant, 

 after the formation of two consecutive leaf-rosettes, can, in 

 the third summer, form a shoot-portion with elongated inter- 

 nodes, although a comparatively weak one, terminating in 

 an inflorescence. Generally, the necessary vegetative-stage 

 preceding the flowering is, no doubt, of longer duration. The 

 vegetative stage of the innovation-shoots extends as a rule 

 over 2 years. 



P. hirsiita and P. lanata difTer essentially from each 

 other by the faet that the latter has no specially-developed
