The unique morphological basis and parallel evolutionary history of personate flowers in <i>Penstemon</i>.

ABSTRACT:

Premise

Adaptive radiation in ecologically and morphologically diverse plant lineages presents an opportunity to investigate the rapid evolution of novel floral traits. While some types of floral traits, such as flower color, are well-characterized, other types of complex morphologies remain understudied. One example is occluded personate flowers, dorso-ventrally compressed flowers with obstructed floral passageways, which have evolved in multiple genera, but have only been characterized from snapdragon.

Methods

Our study examined the morphological basis and evolutionary history of personate flowers in a clade of Penstemon species that includes three personate-flowered species. We characterized floral morphology and inferred phylogenomic relationships for 13 species i
