Re: [Aroid-l] Biarum tenuifolium ssp. abbreviatum

From: Peter Boyce <phymatarum at gmail.com> on 2018.09.07 at 21:22:15(24041) 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.

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?)
