Select the form of the Liverwort

Leafy Liverworts produce a stem, with 2-ranked leaves. Some liverworts may grow a third set of leaves on the underside of the stem, these leaves are known as the under-leaves. Under-leaves are generally smaller and may present different characters then the main leaves.

Thallus Liverworts do not produce a stem, In stead they grow across their substrate. Generally on the upper surfaces they look as if they have scales, with the scale containing a white pore.
