Evaluating the Monophyly and Interrelationships of Cryptantha s.s. (Boraginaceae).

Cryptantha, an herb in the Boraginaceae family, is found in western North America and western South America, but not the tropics between. This amphitropical distribution has long puzzled scientists. In a recent study, Cryptantha was found to be paraphyletic and was split into 5 genera, including a weakly supported, potentially non-monophyletic Cryptantha s.s.  In all subsequent studies of the Cryptanthinae, the subtribe in which Cryptantha belongs, interrelationships of the species of Cryptantha s.s. were generally not well supported and have a low sample size. The objective of this study is to clarify the phylogenetic relationships in the genus Cryptantha s.s. using genome skimming methods. We aim to illuminate these relationships with strong support using significantly more data from the nuclear ribosomal cistron, the plastome, and mitochondrial genes. With stronger resolution, we can evaluate character evolution as well as amphitropical distribution. Revealing the timing, direction, and number of times of dispersal between North and South America can give us insight to origin of the great biodiversity of these regions.
