The Lemonwood is the only species in its genus, Xymalos. The whorls and ridges on its trunk, visible when the bark peels away, make it one of the easier forest species to identify — the patterns can be quite conspicuous, reminiscent of the geometric lines found in rock art. The strong citrus scent when leaves are crushed clinch identification. The tree is resistant to fire and will vigorously resprout if damaged, forming a more unruly, dense mass of coppice shoots that no doubt provides excellent protection for birds and other species as the forest begins to recover.
The finest specimens at Ferncliffe are very impressive individuals and have inspired the name of one of the trails through the forest.
