Somatic chromosomes of Lepturus repens R. Br. and L. radicans A. Camus have been observed in root tip cells. The former has 2n=54 and the latter has 2n=18. The basic chromosome number of Lepturus may be 9, and all chromosomes are small (Fig. 1.).
It is pointed out that Lepturus and Monerma are karyomorphologically very widely different and that l lonerzna may be a member of Pooideae, while Lepturus can be ascribed to Eragrostoideae, although the two genera are so closely related in external morphology that for a long time they were believed to be congeneric.
I wish to express my cordial thanks to Dr. H. Kihara, Dr. Y. Takenaka, Dr. E. Potztal and Dr. F. A. Lilienfeld for their kindness throughout the present study. Thanks are also due to The Rockefeller Foundation who financially helped me in the trip to Ceylon and India.
