BUFFELGRASS, Pennisetum ciliare (L.) Link, and birdwoodgrass, Cencbras setigerus Vahl., are perennial grasses which have been introduced from Africa and India. Several introductions of these two species have recently received wide publicity as new pasture plants for Texas and other southern states. Both species have limitations from the standpoint of forage and seed production, making it desirable to attempt improvement of the available types through breeding. Cytogenetic investigations were undertaken in order to obtain basic information for the breeding program. Although the two species were investigated independently, strong morphological similarities between them and strikingly similar findings in reproductive details made a joint paper seem desirable. The value of cytogenetic information in a breeding program has been clearly demonstrated in many economic species and needs no further elaboration here. A survey of the literature revealed nothing concerning the cytology and
