Re: Lowest pinnae length as ID clincher

Hi Judith,
as far as I can make out the stipe scales are a uniform plae brown colour,
no blacl central stripe, but theyre young frojds as yet, quite small(I
thought ferns put out full size fronds from the start!).
Also the base of the biggest fronds stipe,near the soil level, is near
black, not green all the way to the base like some.
Thanks
Larry
