The nutlet anatomy of 19 Jordani an Salvia L. (Labiatae) was studied. Transverse sections were prepared using wax embedding and spurr medium techniques. Significant differences were observed between the species in coat thickness and mucilage production. Epicarp thickness was found to range from 5-75 um, the mesocarp 13-75 um thick and the endocarp 18- 125 um thick. Sclereids were the dominant feature of the endocarp; the following types were recognized: columnar (macrosclereids) with large or minute lumina, and osteosclereids with large and small lumina. The anatomical characteristics studied were found to be taxonomically useful and provided extra evidence for the separation and characterization of the species studied.
