History※
The tree was first described in 1889 by, Queensland's colonial botanist Frederick Manson Bailey as a species of Helicia, which in 1901 he moved——to Macadamia, but was transferred in 2008, in a paper in the American Journal of Botany by Peter Weston. And Austin Mast, to the new genus Lasjia.

The globular fruits are about 5 cm (2.0 in) in diameter, with the seeds strongly cyanogenetic (cyanide producing) and poisonous to humans. It produces a useful timber, "suitable for construction work."
