The progress in genetics and cytogenetics of the Gramineae during the past 14 years appears to be fairly comparable in quantity and quality with that made prior to this period. Chromosome numbers are known for more than twice as many species of grasses as were known 14 years ago. Nevertheless, such reports are still unavailable for thousands of the grass species of the world. Some 80% of the grasses are polyploid, and more than were previously recognized have one form or another of apomictic reproduction. Apospory appears to be widespread in the Panicoid grasses.
