Gayophytum comprises a small homogeneous group of species endemic to western North and South America. The species have been variously delimited (e.g., Munz 1932, 1959; Jepson 1936), suggesting that the group is inherently complex. We have attempted, therefore, to obtain a better understanding of it using chromosome cytology, breeding habit, and ecogeographic distribution, together with morphology, but without growing experimental progenies or making hybrids. Our genetic interpretations are… CONTINUE READING
