摘要Phylogenetic relationships within the tribe Gaultherieae (Chamaedaphne, Diplycosia, Eubotrys, Gaultheria, Leucothoe , and Tepuia) were examined with DNA sequence data from matK, ndhF, and nrITS. Parsimony analyses were performed in PAUP* for each gene region, combined chloroplast data, and total combined data. A Bayesian analysis was performed in MrBayes on the chloroplast and total combined data sets. The total combined parsimony and Bayesian analyses both strongly support the monophyly of the Gaultherieae and the wintergreen group ( Diplycosia, Gaultheria, and Tepuia). Diplycosia is monophyletic and nested within part of Gaultheria. In the Bayesian total combined analysis, Tepuia is strongly supported as sister to a clade containing Gaultheria procumbens, Gaultheria hispidula, Gaultheria leucocarpa var. cumingiana, Gaultheria leucocarpa var. leucocarpa, and all sampled Diplycosia species. Optimization of morphological characters emphasized in classifications of the Gaultherieae onto the molecular phylogeny revealed that (1) fleshy calyces evolved either early in the lineage leading to the wintergreen group or later in two separate clades; (2) capsular fruits are plesiomorphic and berry fruits have evolved independently in Diplycosia and Tepuia and once or twice within a large clade containing all sampled sect. Pernettya members and Gaultheria species not exhibiting a berry fruit; and (3) the ancestral state for both the Gaultherieae and wintergreen group is a racemose inflorescence; solitary-flowered inflorescences have evolved at least eight times within the Gaultherieae, with several changes back to racemose or fascicular inflorescences.
