Morella faya

This tree, endemic to Macaronesia, can reach up to 20 meters in height. It is unique in having separate male and female trees, although some individuals with both sexes can be found. The trunk is twisted, the bark rough, and the foliage dense. The leaves vary considerably in shape and size, but are typically dark green with wavy, irregularly serrated edges. The male flowers are clustered in catkins, while the less visible female flowers, upon maturation, produce the "creces" (black, globose fruits). It has a wide ecological tolerance, growing in the presence of water in very different vegetation zones across the islands. It is one of the most important trees in the ecological restoration of laurel forests due to its ability to fix atmospheric nitrogen in the soil.
