In a culture of Alocasia indica (2n : 28), one plant was found to be desynaptic. At pachytene, pairing apparently was complete, but at diakinesis and metaphase I on the average only 2.36 and 1.53 bivalents respectively were found. Desynapsis is of the medium-strong type according to Prakken. Later meiotic stages were irregular and pollen sterility was 95%. The origin must have been spontaneous mutation.

Desynapsis is described in a clone of Saccharum robusturn. The clone was originally collected in 195 1 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 t
