Selagineae and Manuleeae, two tribes or one? Phylogenetic studies in the Scrophulariaceae

Based on results from a cladistic analysis of molecular characters using pa rsimony and Bayesian inference, the tribe Selagineae (Scrophulariaceae, som etimes Selaginaceae or Globulariaceae). is found to have arisen within Manu leeae (Scrophulariaceae). The inclusion of Selagineae into Manuleeae is the refore proposed. The result is corroborated by morphological characters. an d indicates that the typical Selagineae condition with one ovule per ovary locule has arisen several times within the Manuleeae. Two former Manuleeae taxa are excluded from Manuleeae; Antherothamnus and Camptoloma. The former shows affinity with Scrophularia and Verbascum, and the latter groups with Buddleja and related genera. The controversy between parsimony and likelih ood based methods are briefly discussed as is the possibility of historical bias in prior studies.
