latter is the more rare. Polystichum angulare is 
also to be found. Aculeatum may be known from 
angulare by the darker green of the fronds, by 
their staffer habits of growth, and by the prickly 
nature of the pinnse. It is necessary to study 
both Ferns together to be able to decide with cer- 
tainty, at a glance, which of the two is before you. 
Ophioglossum vulgatum grows in the meadows of 
Warwickshire; but the Adder's-tongue is not 
happy in cultivation, and it is so common that, 
like Pteris aquilina or Bracken, few care to cul- 
tivate it. I transplant Ophioglossum yearly to 
the Fernery, but only to see it yearly devoured 
by slugs. Eventually I discarded from the 
Fernery nearly all of the large Ferns, planting 
them in good rich soil in the walks leading to 
the rockery. Filix-mas, Filix-foemina, Lastrea 
dilatata, and the Scolopendriums, grow well and 
handsomely in the shade — indeed they may be 
said to prefer it. 
One of the handsomest foreign Ferns for out- 
door culture is the Struthiopteris germanica. Its
