Abstract

The Loxocarpinae, also known as the “Boea group”, are the subtribe of Gesneriaceae which includes Boea and a number of segregated genera and close relatives. This group currently comprises over 200 species in 15 genera. Here we present the most up-to-date phylogeny, covering all the genera known to belong to the group, based on Bayesian inference and parsimony of the nuclear ITS and the plastid regions trnL-trnF (intron and spacer) and ndhF-trnLUAG (spacers). The results show discrepancies between the current generic delimitation in the subtribe and the clades delineated by the phylogeny. As a result Boea, Damrongia, Paraboea and Streptocarpus are recircumscribed in an attempt to establish a more natural classification and new combinations are made. The new genus Middletonia is described.
