FIGURE 7. Cross-section of the pulvinules of Collaea aschersoniana (a–d), C. insignis. (e–h), C. speciosa (i–l) and C. stenophylla (m–p), and petiole of C. speciosa (q–s): a, e, i, m and q 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. r detail of the trichomes, epidermis, collenchyma, parenchyma, fibers, phloem and xylem. s detail of pith cells. (co = collenchyma; 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, q = 200 μm; b–d, f–h, j–l, n–p, r, s = 50 μm.
