Abstract
A detailed study of meiosis and breeding behavior of Spartina × caespitosa (A. A. Eaton) Fern, and a comparison with S. patens (Ait.) Muhl. and S. pectinata Link, its putative parents, has revealed regular meiotic pairing, relatively high pollen stainability, and a low seed set in the hybrid when intercrossed with other clones of S. × caespitosa or with S. patens and S. pectinata. S. × caespitosa quite frequently occurs and persists under competition amidst juxtaposed clones of rhizomatous S. patens and S. pectinata but there is little evidence of an F2 generation in the wild and it maintains a very localized distribution. Many characteristics of S. × caespitosa are closely similar to those of a species and features of hybrid nature are not easy to define.Keywords
