 N.B. This enumeration of coun- 

 ties is to be received with 

 caution. Examples of the 

 pseudo-Jiidtans state of P. ob- 

 longm are occasionally mis- 

 labelled as heterophyllus ; and 

 it is difficult to avoid con- 

 fusion between this present 

 and the next species, par- 

 ticularly among early or 

 imperfect specimens in the 

 herbarium.

N.B. Confused with the lan- 

 ceolatus on the one side, and 

 with heterophyllus on the 



other side. The doubts 

 shown with some of the 

 specimens (? sp.) cited un- 

 der the preceding species 

 are queries whether they 

 ought to be assigned to this 

 present species instead.
