I've been busy and just skimming through the DIGEST files so if someone as
directed a note to me in the last week I've missed it---please repost to me
directly.
Regarding ruminations on mycorrhizal associations... When on a hike with my
botanist brother I happened to mention that _Capsella bursa-pastoris_ is
sometimes thought to be carnivorous, he expressed surprise and then told me
that as far as he knew, plants in the mustard family (Cruciferae or
Brassicaceae) do not develop mycorrhizal associations that can help in
nutrient uptake in poor soils, esp. those low in P. So a potential solution
to this phylogenetic constraint would be to eat mosquitos! Of course, we're
talking about carnivorous seeds vs. live plants, but the connection is
interesting.
Cheers,
