Fig 1.
Map of Turkey with the grid system classifying the different districts as it appears in the Flora of Turkey [25].
Districts colored in violet and pink correspond to those were populations of Tripleurospermum and Matricaria were collected, respectively (both for genome size assessments and molecular phylogeny). Mixed violet and pink indicates that both Tripleurospermum and Matricaria populations were found in those districts. Codes: * Anthemis Δ Matricaria ○ Tripleurospermum belong to those populations used for phylogenetic reconstruction only (the corresponding number is indicated in Table 1). Map created with mapchart.net.
Table 1.
Provenance and voucher number of the populations here studied, together with ploidy level, chromosome number, holoploid and monoploid genome size and internal standard used.
All genome sizes are first estimates in the taxa concerned with the exception of M. chamomilla var. chamomilla, T. callosum, T. elongatum, T. maritimum, T. melanolepis, T. oreades var. oreades, T. oreades var. tchihatchewii, T. repens and T. sevanense. (1) Information of locality and collection date.

Molecular phylogenetic reconstruction obtained through combined analysis of ITS and 3’ETS sequence data for 45 taxa.
The majority rule consensus tree (50%), based on Bayesian MCMC inference and with Bayesian clade-credibility values (posterior probability > 0.5) above branches, is displayed. A representation of genome sizes in bars (2C and 1Cx, in darker colours) is displayed in the right part of the image. Note, average higher genome sizes of species from clade A (purple) as compared to species from clade B (blue) in Tripleurospermum.

Results of the statistical analyses and comparisons, using the ordinary tests (mostly analysis of regression and ANOVA) and the phylogenetically based generalized least squares (PGLS) algorithms.
