AD FLORAM INDICAM — SAXIFBAGE^ ET AFFINES. 55 



to US to be rather aberrant members of SaxifragecB in its extended 

 significance, than separate Orders ; the former having many points 

 in common with SaxifragecB, as the persistent marcescent sub- 

 perigynous petals, which, and the stamens, are absolutely perigynous 

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

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

 on the genus*. It is not, however, our intention to discuss such 

 questions at length in the " Prsecursores ; ' ' and we therefore proceed 

 with the systematic arrangement of the genera and species.
