Caption: Fig. 3.Ontogenesis of peltate trichomes of Myrsine coriacea (A–E, G) and Myrsine venosa (F and H) leaves. (A, D, E, G, H) Light microscopy. (B and C) Epifluorescence microscopy. (F) Scanning electron microscopy. (A) Cross section of the leaf primordium with a peltate trichome that develops from an anticlinally divided protodermal cell, resulting in the basal cell (bc) and the stalk cell (sc). Subsequently, the stalk cell undergoes a new anticlinal division forming the head cell (hc). (B) Cross section of the young developed trichome, stained with DAPI. (C) Frontal view of the head cell stained with Auramine O. (D and E) Cross section of peltate trichomes after several anticlinal divisions of the head cells. (F) Full developed trichomes in sunken areas of the epidermis. (G and H) Frontal view of mature trichomes.
