Steve,
This is indeed ssp. abbreviatum and looks to be
the Lake Ochrid (Okrid) collection made by Brian Matthews in
the 70s.
Biarum, as with all aroids, have the pistils
receptive before the pollen is shed. However, unlike most
aroids at least some Biarum appear to maintain stigmatic
receptivity until pollen shed and thus are able to
self-fertilize and set fruits with viable seeds.
Received
with that name, at least; opinions from the experts would be
welcome.
The attached picture, which I know is poor, is of
inflorescences on two
plants that opened today. The odor to me is exactly that of a
wood fire
at the beginning of a rain, smoky and slightly acrid, but
Cathy thought
it more a mushroom smell.
What's the pollination biology of Biarum as far as when pollen
is mature
and when the stigmas are receptive? (And are they
self-fertile?)
Thanks,
Steve
