Systematics Section / ASPT Lukas, Laura E. [1], Peters, Melinda [1], Macklin, James A. [2], Davis, III, Charles C. [3]. Identifying a putative hybrid species of Himalayan Gentiana (Gentianaceae). Gentiana (Gentianaceae) is a lineage of ~362 species principally distributed in temperate Asia, Europe, and North America. Gentiana szechenyii, G. hexaphylla, and G. veitchiorum are herbaceous perennials that occur in alpine meadows in the Himalayan region of China and Bhutan, between 3000-4400 meters. Gentiana veitchiorum exhibits intermediate vegetative and reproductive morphologies between G. szechenyii and G. hexaphylla, suggesting that the former may be of hybrid origin. We tested this hypothesis using principle component analysis (PCA) of morphological data, in addition to molecular data obtained from the nuclear and plastid genomes of these species.
