Fig. 232. Inner morphology of the flower as illustrated in Viola tricolor. A, epider- mal cells from the outer surface of the spurred petal showing papillae; B, epidermal cells from the under surface of the petals, some of the cells showing centripetal thickenings, the two without thickenings indicating the epidermal mucilage-cells; C, epidermal cells from the under surface of the petals showing a zigzag outline and short centripetal thickenings; D, surface view of the mesophyll of the petals; E, corkscrew-like hair from the i'nner sur- face of the spurred corolla near the throat; F, a hair from the edge of an anther; G, epider- mal cells of the anthers; H, surface view of the mesophyll cells from the spurred stamen showing collenchymatous thickening; I, surface view of cells of endothecium; K, pollen grain viewed from the side; L, pollen grain examined in water; M, pollen grain observed in chloral solution. are but slightly cutinized, and in surface view are strongly undu- late and appear striate owing to the papillose development (Figs. 232 and 235). The chlorenchyma is made up of rather loose, branching parenchyma cells (Fig. 232, D), with large, intercellular spaces. The cells are free from chloroplastids, may contain
