Figure 5 from: Noblick LR, Sant'anna-Santos BF (2021) Diversity of leaf anatomy within a single leaflet and between leaflets of four Butia (Arecaceae, Arecoideae) species. PhytoKeys 180: 31-52. https://doi.org/10.3897/phytokeys.180.66018
Figure 5 Anatomical changes of the leaflet margins in a 5 cm region near the leaflet centre AButia paraguayensisBB. eriospatha. PVB-SVB = primary vascular bundles transitioning to secondary vascular bundles; SVB-PVB = secondary vascular bundles transitioning to primary vascular bundles. Gone = vascular bundle disappeared or nearly so. Scale bars: 0.5 mm.

FIGURE 4 in Begonia isadorae (Begoniaceae), a new endemic species from Ilha Grande, an island in southeastern Brazil, with notes on leaf anatomy
FIGURE 4. Leaf blade anatomy of Begonia isadorae (Begoniaceae). A. Frontal view of epidermis (Ep) on the adaxial surface showing common cells and glandular trichomes (Gt). Inset shows cross section of glandular trichome occurring sunken on the epidermis. B. Frontal view of epidermis (Ep) on the abaxial surface showing glandular trichomes (Gt) and stomata (St) in groups of two or three. C. Frontal view of epidermis (Ep) on the midrib region showing lines of druses (Dr), emergences forming simple trichomes (Tr) and glandular trichomes (Gt). Inset shows detail of simple trichome. D. Cross section showing unistratified epidermis (Ep) on both sides with emergences forming simple trichomes (Tr), wide layer of hypodermis on both sides, and thin chlorophyll parenchyma (Cp). E. Midrib showing unistratified epidermis (Ep), wide hypodermis (Hp), collenchyma (Co), a continuous layer of chlorophyll parenchyma, formed by spongy (Sp) and palisade (Pp) parenchyma, and two collateral vascular bundles facing each other immerse in a fundamental parenchyma (Fp) with druses (Dr). Fi: fibers, Ph: phloem, Xy: xylem. F. Detail showing the leaf blade with wide hypodermis (Hp), tiny palisade parenchyma (Pp) and spongy parenchyma (Sp) with idioblast (Id). G. Detail of idioblast (Id) submitted to Sudan III test, showing suberized cell walls. H. Emergence forming a simple trichome with tapered apex. Scale bars: A, B, C, H = 50 µm; D = 200 µm; E, F, G = 100 µm.

FIGURE 5. Petiole cross section of Begonia isadorae (Begoniaceae). A. Overview of the petiole, showing epidermis (Ep), cortex formed by collenchyma (Co) and parenchyma (Pa), and vascular bundles (Vb) forming a ring around the parenchymal pith. Dashed circle is highlighting medullary vascular bundles. Id: idioblast. B. Detail showing epidermis (Ep) and collenchyma (Co) with druses (Dr). C. Detail of emergence forming scales (Sc) on the epidermis (Ep). D. Detail of collateral open vascular bundles with phloem (Ph), cambium (Ca) and xylem (Xy). Scale bars: A = 200 µm; B, D = 50 µm; C = 100 µm.
