FIGURE 1. Maximum likelihood tree based on the concatenated data set (ITS, trnL-F, trnS-trnG, psbA-trnH). Bayesian posterior probabilities are indicated above branches, while bootstrap support is indicated below. The first value (bold) refers to the bootstrap support under likelihood, and the second (italics) to the parsimony analysis.
