Phylogeny of the Loeselia clade (Loeselia and Dayia)
Phylogenetic relationships of Polemoniaceae tribe Loeselieae (Johnson et al. 2008). One of four most parsimonious trees recovered from analyses of the combined ITS, matK, trnL intron-trnL-trnF, trnS-trnG, trnD-trnT, and psbM-trnD with indels coded. Branches not present in the strict consensus of the most parsimonious trees are indicated with thick dashed lines. Branches not present in the Bayesian tree are indicated with a thin dashed line. Numbers above branches are base substitutions as reconstructed using parsimony (ACCTRAN optimization); numbers below branches are parsimony bootstrap and Bayesian posterior probabilities, respectively. Black triangle (Lo) represents tribe Loeselieae following Porter and Johnson (2000).
Strict consensus of 1080 trees of 1019 steps from maximum parsimony analysis of nrITS, cp trnL-trnF, trnS-trnG, and ndhF-trnL(UAG) region DNA sequences. Nonparametric bootstrap values are presented above the branches and posterior probabilities below. Status of accessions as self-incompatible (SI) or self-compatible (SC) as determined by crossing studies at RSABG, are indicated in the blue and pink balloons, respectively. Asterisks identify samples displaying profound reduction in flower size. The arrows indicate the two origins of SC: the common ancestor of Loeselia, and in Bryantiella glutinosa. Light yellow boxes call attention to multiple accessions of taxa.
