Very interesting.
Straight agar or a MS formula?

Subject: [iris-species] germinating old iris seed
Â
An iris friend and ASI member in Sydney who is embryo culturing
oncocyclus seed for a few of the Australian growers has recently
emailed the following:"In 1982 I was living in Montana and found some
irises growing in the ditchalongside the road out of town.ÂÂ Later in
the year I stopped andfound lots of seed pods on the now dried out
plants.ÂÂ The localscalled them I. Montana, but the reference books
describe them as I.Missouriensis.ÂÂ No Matter.ÂÂ I collected a few of
the verysmall seed from each of several pods and brought them home with
me.ÂÂThey have been in the refrigerator ever since.ÂÂ In 1986 I tried
togerminate some by EC, no joy. But I couldnât bring myself to throw
themout.ÂÂ Anyway about a month ago I ECd 10, 8 embryos on
agar.ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂToday I have two embryos germinated!ÂÂ There is one
more that isalmost there.ÂÂ Whether they will grow or not I canât say,
but I havetwo germinated from 30 year old seed!"
Indeed Peter has ECd old onco seed too from about this period. Â Peter
has been a godsend to those of us in Australia who want to grow onco
species.

savannarum is far more >common and widespread and usually goes by
hexagona.

Sean,
ÂÂÂÂÂÂ The map of Florida vascular plants shows no Iris savannarum, but
others have said it is a real species and is the one found in this part
of the state. Does SIGNA and AIS count savannarum as a real species?Â
