From comparison of specimens received from Hampe, repre- 

 senting the true P. dentatwn of Menzies, and which exactly 

 correspond to ydiwaegrichen's figures from original specimens 

 of Menzies, it is evident that this species is closely related to P. 

 capillare, Michx., if not a mere form of the same.
