Phylogeny and Evolution of the Species-Rich Neotropical Lobelioids (Campanulaceae).

The Lobelioideae is the largest subfamily of the cosmopolitan bell-flower family, Campanulaceae.  Half of the diversity within the Lobelioideae is restricted to the montane Neotropics (particularly the Andean cordilleras), and the majority of these species are within the three genera Centropogon (212 spp.), Burmeistera (102 spp.), and Siphocapmylus (231 spp.), sometimes referred to as the CBS clade.  The CBS clade is a recent and rapid radiation into the cloud forests of the Andes and Central American mountains that display a great variation in their vegetative and reproductive morphology, habit, and ecology. We expand and improve on previous knowledge on the phylogeny of this clade by increasing taxon sampling via field collections and sampling from herbarium specimens, and by utilizing quickly evolving plastid markers to reconstruct the phylogeny. Current taxonomy of this clade is discussed in light of these evolutionary relationships, including the erection of new clade-based names. The evolution of cardinal taxonomic characters (such as fruit type) is also discussed. The phylogeny is then used to infer patterns of diversification and biogeography in this recent, rapid Andean radiation.
