(Lunularia)
Lunularia is not purely asexual; it can also reproduce sexually (see illustration) with four archegonia arranged in a cross-shaped head (hence the specific name cruciata) bearing diploid sporophyte plantlets. As in other liverworts, the main plant body or thallus is a haploid gametophyte. Like many other liverwort species, Lunularia produces a dihydrostilbenoid growth hormone, lunularic acid, that is reported to be a growth inhibitor of liverworts.
