Teucrium brevifolium Schreb.

The nutlet is light brown and elliptic (1.46 × 0.8 mm) of surface densely covered with non-glandular hairs, decreasing towards the abscission scar. The hairs attain two types; a short, non-articulate, conical or slightly falcate, and micro-papillate and a long, articulate, with smooth basal and micro-papillate apical cell. The nutlet sculpture is striate to ruminate. The abscission scar is elliptic and occupies about 62% from the nutlet length ( Table 2 and Fig. 1 , 27–31).
