Stellate plant hair. Polarised light micrograph of a stellate hair on the surface of a Deutzia scabra plant. These plant hairs (trichomes) covering the epidermis. The stellate (star-shaped) ones help reduce water loss from transpiration, and can also deter browsing by herbivorous insects. Magnification x230 when printed at 10 centimetres across.
