Untangling a Mistaken Identity: Describing the Two Species Within Aphyllon fasciculatum.

Recent phylogenetic studies of the western hemisphere broomrapes (genus Aphyllon) suggests substantial undescribed diversity within the species Aphyllon fasciculatum, which was found to be non-monophyletic with cryptic diversity corresponding to unique host preferences. Morphometric data was collected from herbarium specimens and inaturalist observations and analyzed using principal component analysis and multiple component analysis. Overall there is a high degree of overlap in physical characteristics, but the plant coloration, shape of the corolla lobes, and calyx cup depth and lobe length were distinctive between two groups within A. fasciculatum. This information will allow for the description of a new species within the genus Aphyllon and the creation of keys that more accurately describe its diversity.
