 former having 



pengynous petals, which, and the stamens, are absolutely perigyn^ 

 in some Antarctic species, indicating, as it appears to us, strong 

 affinities with this group than M. Planchon admits in his able pa] 

 on the genus*. It is not, however, 



our 



questions at length in the "Prsecrtrsores;" and we therefore proceed 

 with the systematic arrangement of the genera and species.
