They look like archegoniophores rather than antheridiophores to me,
though that's only going from aussie marchantiophytes. Here the
antheridiophores are shorter, smaller and have flat upper surfaces
(rather than having fingery projections as the ones in the photo). Plus
IIRC the archegoniophores release their spores from the upper rather
than the lower surface.
I'm only going by what the book says. I'm no botanist (ptui!) 8-)
BTW, I haven't come across the word polymorpha - what does it mean?
many shaped, or maybe more accurately multiple shaped
Cheers,
