FIGURE 1. Best-known ML tree obtained from the combined nuclear ribosomal regions ITS and 5'-ETS and psbA-trnH and trnT-trnL intergenic spacers data set. The tree is rooted under the assumption that Dischidia and Hoya are mutually monophyletic. The part of the tree including clades V and VI, here contracted, is presented in Fig. 2. Bootstrap support values>60 (based on 100 replicates) are indicated at branches. Voucher information and GenBank accession numbers for H. papaschonii can be found in the Materials and Methods section. For voucher information and GenBank accession numbers of all other sequences see Wanntorp et al. (2014, electronic supplement S1). Species with a shrubby habit are marked by a round symbol; species with short-lived peduncles are marked by a square symbol. In the case names have been updated, the original name is indicated in brackets.
