I have, on several occasions in the past, come across literature
references citing Dipsacus fullonum as a carnivorous plant - the
odd pitcher shaped "leaves" encircling the peduncle being the
means by which this singular plant captures its prey. This has
never made much sense to me - what benefit to the plant can there
possibly be by adopting a carnivorous mode of nutrition so late
in its development? Surely these elaborate structures are merely
a means to protect the developing inflorescence and its precious
gametes from the attentions of hungry insects?
I have seen no mention of Dipsacus on the 'net in the short time
I have subscribed to the CP group, nor in the grow and seller
lists. Has this matter been settled long ago? Your comments
would be much appreciated.
Best regards for now
