Regarding sub-carnivory in plants, I have seen a couple of articles
regarding the wild ancestor of the potato, which spears nematodes
and small insects on the hairs on its tubers, and the teasel, which
drowns insects in water that collects at leaf joints. There is no
evidence that either uses enzymes to digest the victims, but given a
few million years..........
Here in the UK, Byblis Liniflora is a short-lived perennial if given
artificial help - I once had a plant continuously in flower for over
12 months. I don't think it has the capacity to go dormant as there
is no part of the plant suitable for storing enough fuel to restart. It
doesn't have thick roots like Byblis Gigantea (so root cuttings are
out), and it is too straggly for resting buds. Given how prolific a
self-seeder it is, I don't think it would have needed to evolve a
dormancy mechanism.
Good Growing, NigelH
