Cat's Eyes and Popcorn Flowers: Phylogenetic Systematics of the Genus Cryptantha s. l. (Boraginaceae)
Cryptantha (Boraginaceae) is a group of approximately 200 annual and perennial species, representing two-thirds of the diversity within subtribe Cryptanthinae. The genus exhibits an amphitropic distribution, occurring in temperate and desert regions of western North and South America. Fifty samples of 45 species of Cryptantha s. l., exemplars of the related genera Amsinckia, Pectocarya, and Plagiobothrys, and four outgroup taxa were sequenced for two gene regions, the nuclear ribosomal gene, ITS, and the trnL UAA intron region of the chloroplast genome. These data were used to assess phylogenetic relationships using parsimony, maximum likelihood, and Bayesian inference methods. Cryptantha s. l. was found to be polyphyletic, with its members placed among several well-supported clades. Based on these analyses, we propose resurrection of the genera Eremocarya,
