Journal ArticleDOI
Allozyme divergence and intraspecific variation in Coreopsis grandiflora (Compositae)
TL;DR: The electrophoretic evidence is concordant with the high morphological similarity between var.
Journal ArticleDOI
Allozyme Divergence Between Coreopsis basalis and C. wrightii (Compositae)
TL;DR: The enzyme data and morphology are con- cordant with the hypothesis that speciation occurred via chromosomal repatterning with minimal divergence at genes coding for isozymes, and Isozyme data support the hypotheses that C. basalis and C. wrightii are more closely related to each other than either is to the other two annual species of sect.
Journal ArticleDOI
Pollen competition and relatedness in haplopappus section isopappus (compositae). ii.
TL;DR: Pollen competition in mixed pollinations involving a time handicap was studied among the five aneuploid members of section Isopappus of Haplopappu, finding that the genetic relatedness of the taxa in the section generally parallels morphological distinctness.
Journal ArticleDOI
Coreopsis nuecensis (Compositae) and a related new species from southern Texas
TL;DR: An aneuploid chromosome series ofn = 6, 7, 8, 9, and 10 inCoreopsis nuecensis Heller was analyzed for morphological, distributional, and genetic correlations with the chromosome number classes and it is proposed that then = 9, 10 segment be recognized as a new species, Coreopsisnuecensoides.
