Re: Biarum tenuifolium ssp. abbreviatum

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.

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.

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
