and more semicircularly arched in median vein of leaf blade (Plate VI, Pigs. 2, 4; Plate VIII, Pig. 1). Phloem 1 -3-seriate in petiole and median vein of Lithospermum purpureo-coeruleum L. as stated by JODIN for the entire genus. I am greatly indebted to Prof. S. SÁRKÁNY for his support of my work, and to J. STIEBER, assistant professor, for the valuable advices. I am also thankful for the support of J. SZUJKÓ-LACZA, and G. FEKETE, leaders of our research team. References BRAUNE, W., LEM AN, A &TAUBERT, H. (1967) : Pflanzenanatomisches Praktikum. — Jena. ESAU, K. (1969): Pflanzenanatomie. — Jena, p. 24-347.
