Franco-Estrada D., Sánchez D., Terrazas T., Arias S., Phylogenetic analysis of Peniocereus (Cactaceae, Echinocereeae) based on five chloroplast DNA markers, Brazilian Journal of Botany, 2021, 44(4):903-916, doi: 10.1007/s40415-021-00774-0
The abstract describes an analysis of five chloroplast markers and a broad set of genera related to Peniocereus. In the results, Peniocereus formed a distinct clade sister to a group including Carnegiea, Lophocereus, Marshallocereus and Nyctocereus. Character reconstructions also addressed the history of slender stems and a climbing habit. The accessible account covers the paper’s abstract.
