Within 15 - 20 years, the Lancewood will mature. Its jagged edged leaves begin to smooth and either become unifoliate, three-foliate or five-foliate. The apex branches while the stem thickens. It is theorized that once the Lancewood surpassed the Giant Moa's height, it was safe to transform into its adult form pictured above. Another theory suggests that the morphological change occurs in response to the climatic changes that the trees undergo as they transition from the understory up to the sub-canopy.
