Biarum tenuifolium ssp. abbreviatum

From: Steve Marak <samarak at gizmoworks.com> on 2018.09.07 at 20:22:21(24039) 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?)

I gave it away when I moved. Sigh. HTML +More On 7 September 2018 at 15:22, Steve Marak wrote: Received with that name, at least; opinions from the experts would be welcome.

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.

From: Jason Hernandez <jason.hernandez74 at yahoo.com> on 2018.09.08 at 01:06:04(24042) Sorry I can't help with the ID; I was mainly intrigued by the descriptions of the scent. A mushroom smell would imply that it is pollinated by fungus gnats. As to the smell of a wood fire, I am trying to think what pollinators would be attracted to that? I cannot find information on the pollination biology, but the pattern of female anthesis, followed by male anthesis, is found throughout the Araceae, which means that a flower cannot pollinize itself; you would need the pollen from one flower to pollinate another flower.

From: Peter Boyce <phymatarum at gmail.com> on 2018.09.09 at 02:40:44(24050) Hi Jason, Actually there are quite a lot of aroids that self-fertilize - the best know of course is Anthurium scandens. In the Mediterranean Arum idaeum, Arum hygrophilum, several Biarum, and Arisarum vulgare are all capable of producing fruits with viable seeds from a single inflorescence. Arum dioscoridis in some of its populations also. Here on Borneo Amydrium medium seems capable of setting fruits from a single inflorescence is the absence of other nearby plants.
