FIGURE 3. Ambrosina bassii -Tunisia: Morphological leaf variability of the form (A, B–C); the margin (D, E–F); the color of the blade and the veins (G, H, I, J, K–L); the base (M, N–O) and the apex (P, Q, R–S). The blades are green, light green or sage green, ranging from broadly elliptical shape (width / length> 0.75), elliptical (width / length ranges from 0.5–0.74) to narrowly elliptical (width /length <0.49) (Figs. A–C). The blade can also be stained with purple-black, with arched top, obtuse, very obtuse or lobed (Figs. P–S) and cordate base, rounded or clasping (Figs. M–O). The veins are more or less parallel arising from the petiole insertion green, light green or dark green. The margins of the leaf blade are wavy, tense or not corrugated (Figs. D–F).
