Diplolaena

Diplolaena is monophyletic with robust support (1.00 PP, 100% JK; Fig. 1 , 3 , S 1 , S 2 ; 6 of 15 species sampled), but its relationships with other genera are inconclusive. Wilson et al. (1998) and Wilson (2013 g) indicated that most species grade into each other and offered no discussions of relationships within the genus or between it and other genera. In the combined (0.96 PP, 57% JK) and nuclear (0.99 PP, 58% JK) analyses Diplolaena grouped with Clade 6 ( Chorilaena + Rhadinothamnus + Nematolepis ) with weak support, although in the plastid analyses (0.97 PP) it was sister to an unsupported clade comprising Clade 6 and the Phebalium + Microcybe clade. No clear groups are identified within Diplolaena and so no formal infrageneric taxonomy is proposed here. Diplolaena is also discussed under Pollination below.

Fig. 3. Bayesian 50% majority-rule consensus tree of combined molecular data, with thick lines showing supported clades (≥0.95 PP). Jackknife supports from MP analysis are indicated with icons above branches: 100% JK (solid triangles); 90–99% JK (solid squares); 75–89% JK (open triangles); 50–74% JK (open squares). This tree details relationships within the more derived clades. New or revised sectional assignments are indicated in bold. Clade numbering has been defined in the text.
