 NATURALISING IN HOME GROUNDS 



Lack of dense shade and constant moisture 

 exclude the beautiful Clinton's wood fern 

 (Dryopteris cristata, var. Clintoniand) and 

 both woodwardias from ordinary cultural 

 lists. This is to be regretted. The first 

 named will grow readily anywhere, attaining 

 good size and colour; but the fronds are so

 border if it would adapt itself.
