Teucrium capitatum L.

The nutlet is dark brown and elliptic (1.04 × 0.66 mm), while the surface is glabrous with deep areoles becoming shallower towards the abscission scar. The nutlet sculpture is reticulate of isodiametric cells with depressed anticlinal and convex external periclinal walls. The abscission scar is orbicular and occupies about 55% of the nutlet length ( Table 2 and Fig. 1 , 9–11).
