Supplementary Information

Supplementary Fig. 1. Comparison of microXCT cross section images of flowers 1 (upper row) and 2 (lower row) obtained using original scanning files provided by Shi et al.1. a,b, Images from file QUST-AM32127-1 as published by Shi et al.1 in their Supplementary Information Fig. 26j,l. c,d, Images obtained from QUST-AM32127-1 in this study. e,f, Images obtained from QUST-AM32127-2 in this study. To be consistent with the published figure (a) of Shi et al.1, (c) and (e) were mirror-inverted. Note missing stamens in (a) and (b) encircled in red, compared to (c) and (d), and better resolution in (e) and (f). For abbreviations in (a) and (b), see Shi et al.1. Scale bars (apply to each row): a,b = 0.2 mm.
