Thefolium vermis is a short, narrow, concealed band at the posterior extremity of thevermis, consisting apparently of a singlefolium, but in reality marked on its upper and under surfaces by secondary fissures.
Laterally, it expands in either hemisphere into a considerablelobule, the superior semilunar lobule (lobulus semilunaris superior; postero-superior lobules), which occupies the posterior third of the upper surface of the hemisphere, and is bounded below by thehorizontal sulcus.
The superior semilunar lobules and the folium vermis form the lobus semilunaris.
