Plant DNA extraction - ethanol and dried plants

[Vitor Miranda]

Dear colleagues,

I have extracted DNA from fresh plant material with no problems, but
from dried (herbaria) tissue it has been a real problem.
Does anybody know a successfully protocol to extract DNA from herbaria
material?

Other question: I never tried to use material preserved in ethanol. Is
it possible to get DNA from this kind of  material?
Any suggestion is very welcome ;-)

Thanks in advance,
Vitor.
