Magnolia (Magnolia spp.) consists of about 80 species from Asia [50], West Indies [8], Central/South America [10] and North America [8]. Some species separations are possible based on microanatomy. The genus Magnolia is dedicated to Pierre Magnol (1638−1715), professor of botany and medicine and director of the botanic garden at Montpellier, France.

The Tree: Magnolia trees can reach heights of 80 ft (24 m), with a diameter of 3 ft (1 m).
General Wood Characteristics: The sapwood of magnolia is creamy white, while the heartwood is light to dark brown, often with greenish to purple-black streaks or patches. The wood is even-textured and moderately heavy, fairly hard and straight grained. It resembles yellow poplar (Liriodendron spp.). Magnolia is moderately stiff, high in shock resistance, and low in shrinkage. It has no characteristic odor or taste.
