Figure 8. Details of the sepal and petal.

Figure 8.

(A-B) stereomicroscopy; (C) (E-G) fluorescence light microscopy; (D) TEM; (H) SEM. Bar = 1 mm except otherwise annotated. (A) A petal with a narrowing base. PB22280. (B) A partial petal from the Flower in Figure 3d–e, with the longitudinal rib (to the left) forking at the base (arrow) and the rib-free laminar area to the right. PB22223. (C) Elongated epidermal cells of the petal in Figure 8b . PB22223. Bar = 0.1 mm. (D) Transmission electron microscope view showing the cuticle (left, light color) of a petal. PB22223. Bar = 2 μm. (E) Elongated epidermal cells not in strict longitudinal files in the laminar portion of the petal in Figure 8b . Note the two newly formed epidermal cells (arrow). PB22223. Bar = 0.1 mm. (F) Ribs with elongated epidermal cells (left and right) alternating the between region with less elongated cells (middle) of the petal in Figure 8b . PB22223. Bar = 0.2 mm. (G Elongated (above) and isodiametric (below) epidermal cells on the sepal of Flower in Figure 3d–e. PB22223. Bar = 0.1 mm. (H) A stoma on the bract of the flower (marked by white arrow in Figure 2h). PB22224. Bar = 5 μm.
