A molecular phylogenetic assessment of Monopyle (Gesneriaceae).

Monopyle Moritz ex Benth. is a group of terrestrial herbs distributed from Guatemala southward into northern South America. The genus is comprised of 22 described species with many new taxa currently submitted or in press. Species in the genus have campanulate flowers with numerous color patterns on the lobes or interior, anisophyllous leaves, and uncinate trichomes on various surfaces of the plants. Monopyle is morphologically complex like many other genera in Gesneriaceae and has been difficult to define with morphology only. Molecular phylogenies utilizing a nuclear and chloroplast region have shown that this complex genus may be an assemblage of two or more evolutionarily distinct genera. Extensive sampling and the use of multiple molecular markers have been invaluable to delineate Monopyle from these other closely related genera, as well as separating species within the genus. This work has also shown that the number of species in the genus has been considerably underestimated, which has been noted in other groups in the family. Future research into inflorescence and floral development will be used to strengthen the evolutionary relationships between the taxa.
