    Liverworts

    For many years I have been growing Sphagnum mosses as a medium for my carnivorous plants, so naturally one gets an acquaintance with other mosses that spring up. I also. annually, go around the local terrestrial orchid population and attempt to photo-document them and whilst doing so come across other mosses. This in turn generated an interest in other Bryophytes that associate with these plants. Lichens and Liverworts in mosses and yet more Lichens and Liverworts on rocks and branches. Lichens are of course not plants, they're a symbiotic relationship of a fungi with an alga, but the liverworts most certainly are and are members of the earliest plants to colonise the land. Anyway, enough prattle.

    Here's a couple of photos of Marchantia polymorpha showing the gemmae pots.





    The images are not quite as sharp as I'd have liked them but at this time of year the light just isn't that good for macro work.

    While looking at some interesting mosses a few years ago, I came across these plants - which I'd never seen before. I suspect they are a form of liverwort - is my guess accurate?

    Ron, I would say so, they just aren't showing the sexual characteristics of Fred's above.

    I also love the Bryophytes. Someone really needs to do a nice book on them. I had one book years back: http://www.timberpress.com/books/mos.../9780881923704

    I originally was very fond of the liverworts that showed up in my pots. Eventually however, I noticed allelopathic tendencies, which in some cases, were rather severe. On a kayaking trip in the NJ Pine Barrens, this particular species of liverwort often covered the banks and absolutely nothing else grew there (not the one in the pics). Upon return, I did some googling which seemed to confirm my fears. Now, I consider those long stringy strands as the enemy (but typically not easy to eradicate).

    When I came upon the Snake Liverwort thallus in habitat, I was very impressed by it's appearance. Do all liverworts demonstrate allelopathy?

    A couple of photos of what I believe are Lunularia cruciata. Photographs taken on Xmas day or Dies Natalis Solis Invicti to us oldies.





    Edit: The plants shown here I'm still unsure of identification.
