SEM x100 - Autumn olive leaf (critical point dried) adaxial view
A scanning electron micrograph (SEM) of the upper side of an Autumn Olive leaf, magnified x100. The upper surface of leaves is dark green to grayish-green in colour, while the lower surface is covered with silvery white scales, a conspicuous characteristic that can be seen from a distance. The small light yellow flowers, borne along twigs, bloom in late April and May. Autumn Olive, Elaeagnus umbellate, is of the Family Elaeagnaceae. This is a temperate and tropical family of shrubs and small trees, the exterior of whose leaves and young branches are covered with stellate and peltate trichomes, which are often have sufficient density to give a silvery or brown appearance. The leaf is dorsiventral. Both surfaces have very prominent trichomes. Trichomes are of considerable importance in comparative systematic investigations of angiosperms. Trichomes are epidermal outgrowth of diverse form, structure, and function. The overall surface appearance, indumentum, of the Autumn Olive is stellate. The structure is star-shaped, multiangulate, rotate (in one plane), and stalked.
