There are twenty other genera each of which. might as well 
have been selected for comment as this classic one called Adiantum. 
A glance at any one of them reveals a character and quality in this 
booklet that make it, at least for this present time, unique, also 
praiseworthy beyond all that we have tried to say ; and the botanists

instalments of a primer of local botany that is so accurate, so simply 
honest and true in every detail, and withal so erudite.
