 abound, but woods, old walls and trees have all their special 

 tenants. Remember also when collecting, always choose good 

 specimens, and also plenty of them, for many who are interested 

 in these elegant plants may have but little opportunity to gather 

 them, and others who have, may yet add to their collection by 

 exchange with their friends ; kept in a dry place, they may be 

 preserved good for centuries.

 you, and the generation yet for to come may haply complete them
