FIGURE 9. Cross-section of the petiole (a–c) and pulvinus (d–k) of Collaea insignis (d–g) and C. speciosa (a–c, h–k): a, d and h general aspect. b detail of the trichomes, epidermis, collenchyma, parenchyma, fibers, phloem and xylem. c detail of pith cells. e and i detail of the adaxial surface. f and j detail of the abaxial surface. g and k detail of the vascular bundles highlighting the crystals. (co = collenchyma; ep = epidermis; fi = fibers; pa = parenchyma; ph = phloem; pi = pith; tr = trichomes; xy = xylem). Scale: a, d, h = 500 μm; b = 200 μm; c, e–g, i–k = 50 μm.
