abstract = {Boraginaceae tribe Trigonotideae comprises a heterogenous assemblage of taxa, many of which have been shown to belong to widely divergent lineages in Boraginaceae in the recent past, with some taxa now assigned to three of the four currently recognized tribes of the Boraginaceae sensu stricto, namely the Cynoglosseae, Echiochileae, and Lithospermeae. The systematics of Moritzia and Thaumatocaryon, the only endemic South American genera of Boraginaceae, have been controversially discussed in the past, and their most recent placementwas in Trigonotideae. The present study investigates the phylogenetic relationships of Trigonotideae based on micromorphology and molecular data (ITS including 5.8S rRNA, trnL-trnF spacer). Molecular data show that Trigonotideae are polyphyletic, and none of its members is at all closely related to Trigonotis itself. Moritzia and Thaumatocaryon are closely allied to each other and are the sister group of the Old World Boragineae. Flowers, pollen, and fruit morphology strongly support this systematic placement. Extant (native) Boragineae are absent from North America and had not previously been reported from South America, whereas members of the Cynoglosseae, Echiochileae, and Lithospermeae have been reported from both continents. Moritzia and Thaumatocaryon are thus the only native representatives of Boragineae in the Americas and represent an unexpected western Eurasian/South American disjunction. However, several (widespread and abundant) fossil taxa from the Cenozoic of North America (especially species of Prolithospermum) can be confidently placed into Boragineae. Extant Moritzia/Thaumatocaryon likely go back to a lineage which reached North America from Europe and then migrated into South America, with subsequent extinction in North America.}
