Re: Tree-fern query from Hawaii


Angiopteris evecta is also native to Africa and Madagascar.  My  original 
plant is of Madagascar origin, by way of Jamaica (where it has  colonized in the 
Blue Mountain region).
Next question, how many species are there?  Answer, no one  knows.  There are 
a few distinctive Angiopteris such as Angiopteris smithii  (a once-pinnate 
form), Angiopteris fokiensis (a species in China-Viet Nam, where  it is thought 
to be a complex with stipes that are bumpy), A. angustifolia, that  has narrow 
pinnules (and then this one also goes by the name of A.  palmiformis).  
Taxonomists put the number as few as 11species or as many as  111 (and many of 
these are probably varieties of A. evecta). There are a few  species on our fern 
society website:   http://tfeps.org/angiopteris_sp.htm
