Abstract
Desynapsis is described in a clone of Saccharum robustum. The clone was originally collected in 1951 from New Guinea. The diploid chromosome number is 2n=80. The maximum number of bivalents present was eight. The number of univalents ranged from 64 to 80. Meiosis was very irregular. On selfing the clone did not give progeny.
