(bryology) “lying under; an oblique leaf insertion in which the antical (distal) leaf margins are oriented toward the ventral stem surface; when viewed from above, the antical leaf margins will lie under or be overlapped by the postical (proximal) leaf margins of the leaves directly above. [This type of insertion is associated with an upward curvature of the apex, coupled with a dorsal tilt of the apical cell] found in various leafy liverworts” (Magill);

- folia leniter succuba pauca brevia valde oblique inserta, leaves lightly succubous, few short strongly obliquely inserted.

- insertio folii dorsali modice succuba, with the dorsal insertion of the leaf moderately succubous.
