Crystals in the mesophyll and midveins of leaves. A. Druse in the midvein of Randia hidalgensis (artificially coloured in yellow, from M. Aguilar 9, MEXU). B. Druse in the midvein of R. capitata (arrow, from R. Medina 5703, MEXU). C. Druse in mesophyll of R. capitata (artificially coloured in yellow, from A. Bonfil 275, FESC). D. Druse in mesophyll of R. xalapensis (arrows, from A. Torres-Montufar 664, MEXU). E. Druses in mesophyll of R. thurberi (arrows, from L. Albarran 7, FESC). e = epidermis, p = parenchyma, pp = palisade parenchyma, sp = spongy parenchyma, x = xylem.
