 1/. May— Sept. v. v. This species, generally known 

 by the name of IFhite Clover, makes its appearance 

 v/herever lands are cleared of timber, in the most re- 

 mote parts of the country ; I have seen it springing 

 forward on new plantations, from sixty to one hun- 

 dred miles distant from any place where it naturally 

 was found. A num^ber of plants of this description 

 have struck ray attention, among which are FerbaS' 

 cum Thapsus and Senecio hieracifolius in particular, 

 whose dissemination is really problematical.
