The Marchantia species are found not only in the bush, but also in gardens, plant pots .... anywhere it is cool and damp. The thallus ( the vegetative growth of a plant which isn't divided into stem and leaves) is waxy-looking, often with little circle things (gemmae cups). At certain times of the year little star-shaped structures on stalks appear and these can make the plant more noticeable.
The gemmae cups are for vegetative (asexual) reproduction. In the top cup you can see the little round gemmae, which will get splashed out and will develop into another liverwort plant.
This is one often found in gardens as well as in the wild.
All those structures with "arms" are the female reproductive parts.
If you look hard enough you will also see some gemmae cups.
This image shows both male (brown) and female (green) reproductive structures. The female structure is not as finely divided as in M. foliacea.
This species is easily recognised by the large pores on the thallus.
