Resumen:
Oenothera sect. Calylophus is a North American group of 13 recognized
taxa in the evening primrose family (Onagraceae) with an evolutionary
history that may include independent origins of bee pollination, edaphic
endemism, and permanent translocation heterozygosity. Like other groups
that radiated relatively recently and rapidly, taxon boundaries within
Oenothera sect. Calylophus have remained challenging to circumscribe. In
this study, we used target enrichment, flanking noncoding regions, gene
tree/species tree methods, tests for gene flow modified for
target-enrichment data, and morphometric analysis to reconstruct
phylogenetic hypotheses, evaluate current taxon circumscriptions, and
examine character evolution in Oenothera sect. Calylophus. Because sect.
Calylophus comprises a clade with a relatively restricted geographic
range, we were able to extensively sample across the range of
geographic, edaphic, and morphological diversity in the group. We found
that the combination of exons and flanking noncoding regions led to
improved support for species relationships. We reconstructed potential
hybrid origins of some accessions and note that if processes such as
hybridization are not taken into account, the number of inferred
evolutionary transitions may be artificially inflated. We recovered
strong evidence for multiple evolutionary origins of bee pollination
from ancestral hawkmoth pollination, edaphic specialization on gypsum,
and permanent translocation heterozygosity. This study applies newly
emerging techniques alongside dense infraspecific sampling and
morphological analyses to effectively reconstruct the recalcitrant
history of a rapid radiation. [Gypsum endemism; Oenothera sect.
