Fig. 2.

Box and whisker plots (median, percentiles, range) of 15 morphoanatomical characters analysed in 1050 wild (grey) and inbred (white) individuals of the three species of B. distachyon s.l. complex. (A) Variables that significantly discriminate B. distachyon versus B. stacei versus B. hybridum. (B) Variables that significantly discriminate B. distachyon versus B. stacei + B. hybridum. (C) Variables that significantly discriminate B. hybridum versus B. distachyon + B. stacei. (D) Variables that do not discriminate between species.
