Barry, where has the gnat-pollination of Asarums been published, please? =The
notion is very pleasing.

Where I am, in southwestern British Columbia, many Asarum spp. and their =kin
have produced flowers in the past few weeks; this is also the season of
billows of tiny, almost invisible gnats.

Supplementary question: Do we still believe that ants distribute the seed=s?
>From observation that seems plausible, but the gnats are new and delightf=ul.
