Re: Rumorpha

Mary:

We have found many different forms of Rumorpha adiantiformis here in South
Africa.  The smallest are about 18" tall and the largest are 4-5' tall. 
We found one particularly nice form that has very thick, rubbery-like
leaves on a high pass.  I certainly hadn't realized how variable this
species can be.
