Caption: False-colour scanning electron micrograph of an unopened flower bud of the house plant, Primula malacoides, a native of China. The plant is noted for the covering of glands, which secrete a floury white substance called farina (yellow fluff). Farina covers the flowering stalk, buds & sepals. The waxy secretion from the farina glands protects the flower from cold & condensation of moisture. The sepals, or calyx (green), form the outer layer of the bud, protecting the unopened petals, or corolla (pink), of the flower. Stomata (breathing pores) are visible on the surface of the sepals as ovals with splits in middle. Magnification: x14 at 6x4.5cm size.
