FIGURE 6. Cross-section of the midribs of Collaea aschersoniana (a–d), C. insignis (e–h), C. speciosa (i–l) and C. stenophylla (m–p): a, e, i and m general aspect. b, f, j and n general aspect of the adaxial surface, highlighting the crystals. c, g, k and o general aspects of the abaxial surface. d, h, l and p detail of the vascular bundle. (co = collenchyma; cr = stomatal crypts; ep = epidermis; fi = fibers; pa = parenchyma; ph = phloem; pi = pith; tr = trichomes; vb = vascular bundle; xy = xylem; arrows = prismatic crystals). Scale: a, e, i, m = 200 μm; b–d, f–h, j–l, n–p = 50 μm.
