Teucrium zanonii Pamp.

The nutlet is dark brown and elliptic (0.85 × 0.60 mm) of glabrous surface with shallow areoles, shallower towards the abscission scar. The nutlet sculpture is reticulate of isodiametric cells with raised, wavy anticlinal and concave external periclinal walls. The thickness of muri is 1.67 μm and the diameter of lacuna is 11.67 μm. The abscission scar is elliptic and occupies about 56% from the nutlet length ( Table2, Fig. 1 , 24–26).
