Re: Lowest pinnae length as ID clincher


<In the case of many dryopteris species it is the lowemost pinnule next
to the rachis or center stem, referred to as basiscopic, is often used in
the key and to help identify certain species.  It may be smaller than the
adjacent basiscopic pinnule or larger>

So my fern has a larger basiscopic pinnule, and is rherefore a Dryopteris!
