Incubous

Incubous

The term incubous is used to describe the way in which the leaves of a leafy liverwort are attached to the stem. If you were to look down from above (dorsal side) on a liverwort where the leaf attachment is "incubous", the upper edge of each leaf would overlap the next higher leaf along the stem. Because of this, the upper edge of each leaf is visible from above, but the lower edge of each leaf is obscured by its neighboring leaf. The opposite of "incubous" is succubous.
