Teucrium campanulatum L.

A brown and elliptic nutlet (1.30 × 0.77 mm) of surface moderately covered with glandular hairs changing to glabrous towards the abscission scar. The hairs are long or short, articulate, micro-papillate, with one-celled head. Reticulatesurfaced oil glands are uniformly distributed with dense manner along the nutlet surface. The nutlet sculpture is obscure due to the coverage of hairs and oil glands. The Abscission scar is elliptic and occupies about 68% from the nutlet length ( Table 2 and Fig. 1 , 32–36).
