The somatic chromosome number of a form of Signal grass (Brachiaria brizantha Stapf.), Puerto Rico P.I. No. 1525, introduced from Ceylon, was found to be 36. Only 15 percent of the florets studied developed karyopses. The meiotic behavior of chromosomes at microsporogenesis was irregular. Frequent lagging univalents at anaphase 1 and micronuclei in the spore quartets may account for the low seed-set of this form. More improvement of this character is expected in Signal grass through further research in genetics and by the introduction of more forms and varieties. A field description of Signal grass is given. Signal grass was compared to Guinea grass (Panicum maximum Jack.) as to agronomic behavior. It showed desirable characteristics, besid...
