Polarised light micrograph of a tangential section of the mature wood of the English elm (Ulmus procera). Medullary rays are seen running horizontally. Elm is a deciduous tree which can grow up to 35m and its timber is valued for furniture manufacture. Cross-sections of medullary rays (red with blue circles) are seen alongside longitudinally sectioned vessels with intervessel pits (blue with red circles). Magnification: x68 at 10cm wide. | |
