Abstract
Somatic chromosomes of twenty one grass species were examined. The systematic placing of Sieglingia, Tridens and Chikusichloa was discussed on the basis of distinctive features of the epidermis, transverse leaf section and chromosome situation. Diversity of chromosomes concerning their basic number and size in Festuceae-Festucinae and Andropogoneae was pointed out. The character of the chromosome complements of the other species reported in this paper is in agreement with that of the tribes to which they belong. It is a pleasure to record here a debt of gratitude to Dr. E. Potztal and Dr. J. Ohwi for their kindness during the course of the present investigations.
