FIGURE 1. Anatomy of the petiole and gynoecium of Passiflora coelestis. Petiole with a densely pilose epidermis (*) and mesophyll filled by different sized cells and an aerenchyma (a). Detail on the subdermal layer that takes part in its formation and has idioblasts with phenolic compounds (b). The stigmatic emergences and the solid stylar transmitting tissue (c). Mesophyll with cells of various shapes and with a bigger amount of pectin on its walls (d). Style with aeration on its mesophyll (c) and transmitting tissue with more pectins on its wall (e). Tricarpelate unilocular ovary (f) with the densely pilose outer epidermis (arrow in h) (g and h) with the subdermal layer taking part o its formation and with idioblasts with phenolic compounds inside (*) (h). Bitegmic, crassinucleate anatropous ovules (i), as speciesspecific characteristic the inner integument is bigger and can surpass the outer integument in some regions or remain "aligned" with the outer integument in others with the nucellar cap filling the micropyle (arrow in i and j) (i, j and k). EP (epidermis), VB (vascular bundle), SE (stigmatic emergencies), TT (transmitting tissue), ME (mesophyll), II (inner integument), OI (outer integument), NC (nucellar cap). Scale bars a, c, f, i, j and k—10μm; b, d, e, g and h—5μm.
