title: Data from: Phylogenetic relationships and morphological evolution in the carnivorous genus Philcoxia (Plantaginaceae, Gratioleae)

description: Philcoxia (Plantaginaceae, Gratioleae) is a genus with seven species of
 small herbs endemic to Brazil. It is characterized by underground stems
 and petioles, peltate leaves, and zigzag racemose inflorescences, in
 addition to a remarkable carnivorous syndrome. The phylogenetic placement
 of Philcoxia within tribe Gratioleae has been uncertain since its
 discovery due to its unique morphology and limited data from phylogenetic
 studies. We tested the phylogenetic placement of Philcoxia within
 Gratioleae, increasing the number of species sampled within both the genus
 and the rest of the tribe, and sequencing four regions from cpDNA (rpl16,
 rps16, and trnL introns and the trnL-trnF intergenic spacer) and one from
 nrDNA (ITS1 spacer); we used both parsimony and Bayesian inference to
 reconstruct the phylogeny. Moreover, we assessed both the monophyly of the
 genus and interspecific relationships. Finally, we performed ancestral
 character state reconstructions of 10 morphological characters to infer
 synapomorphies for the genus and specific clades within it. Philcoxia was
 recovered as monophyletic, with maximum support values, as sister to
 Stemodia stellata. Five morphological character states were reconstructed
 as potential synapomorphies for the Philcoxia clade (rosetted herb habit,
 underground stems and petioles, floral resupination, number of stamens
 reduced to two, and number of fertile thecae per anther reduced to one),
 whereas fourwere reconstructed as potential synapomorphies for specific
 clades within the genus (peltate leaves, irregular rosettes, vegetative
 propagation by rhizomes, and presence of tubers). Further anatomical
 studies, in association with ecological data, would provide insight into
 the structure of the underground systems and its adaptive significance,
 and would further elucidate the evolution of carnivory in Philcoxia. Our
 study highlights the need to reassess the concepts and circumscriptions of
 some currently accepted genera of the Gratioleae such as Bacopa, Conobea,
 and Stemodia, and for the tribe Angelonieae.
