Re: [Aroid-l] Fwd: Seeds of Typhonium (Sauromatum) brevipes, or gaoligongense
At the time of the transfer of Sauromatum to Typhonium there were
three species in the genus Sauromatum, one very common, venosum, and the
other two of which I need a few seeds for chemical analysis. This request
has nothing to do with growing. T. venosum is indeed very easy to
propagate. It is actually hardy here in the Cincinnati area, although I
don't know the source of the plants --- did they come from the northern
limits of the range in east Asia or from the Cameroons in equatorial Africa.
I repeat my request: does anyone have, or know of someone who
has, seeds of either or both of the other two former (at the time of the
transfer) species of Sauromatum?
