Character evolution and phylogenetic relationships among species of Monotropeae and Pterosporeae (Monotropoideae: Ericaceae).

Phylogenetic relationships among species of subfamily Monotropoideae have been proposed based on nucleotide sequence data, but the position of Cheilotheca, a rarely collected southeast Asian genus containing two species, remains unknown. Generally, adequate material of all taxa within Monotropoideae has been difficult to assemble for comparison. Consequently, character evolution in Monotropoideae is also poorly understood. We used nucleotide sequencing of nuclear ITS and the plastid trnL-rpl32F region to test relationships among taxa within Monotropoideae, including Cheilotheca khasiana. In light of phylogenic patterns, we considered the evolution of several characters that differentiate species and genera within tribes Monotropeae and Pterosporeae. Finally, we propose some nomenclatural changes based on a combination of both molecular and morphological synapomorphy.
