What has been said in praise of the Polypodium longipes 

 may be repeated with the P. phymatodes , which is a Fern in 

 the same section, and equally deserving of commendation. 



It seems desirable to remark that the Thrips, f Tkrips ado- 

 nidum,J soon produces fearful ravages with the smooth fronds 

 of these Ferns if not destroyed; it will therefore be well to 

 examine the under side of the fronds from time to time, in 

 order that the pest may be speedily eradicated when it makes 

 its appearance, before allowing it a suiEcient length of time to 

 do injury. Certain species seem more subject to this plague
