Abstract
In this study, the morphological and anatomical features of Lamium lycium Boiss. (Lamiaceae) are described in detail. L. lycium has a perennial tap-root, and the stem is ascending and clearly quadrangular. The leaves are simple and broadly ovate to narrowly ovate in shape. The inflorescense is a verticillate cyme. The corolla is purple and the upper lip is hooded. For anatomy, the cross-sections of root, stem, leaf, petiole, calyx, corolla and generative organs were examined and the anatomical features of the taxon are discussed. The morphological features were in most respects congruent with previous reports. However, the anatomy of L. lycium has not been studied before and the results are here compared with trose of previous studies on other members of Lamiaceae. Furthermore, glandular trichomes are illustrated. The results are presented with photographs and tables.
