Phylogenetic and floral community structure in Pedicularis (Orobanchaceae).
Species of Pedicularis are most numerous, endemic, and phenotypically diverse in the mountains of south-central China, where they also tend to co-occur and flower synchronously during the short reproductive season. I examined the composition of Pedicularis "communities" across habitats in this region, reasoning that competition for pollinators might cause co-occurring species to be more distantly related and/or florally dissimilar than expected by chance. Between habitats, I found contrasting correlations of phylogeny and floral trait disparity with co-occurrence, suggesting heterogeneous modes of community assembly and evolution in this lineage.
