Life cycle and dispersal
Spread is primarily by long stolons and bending branches, both of which root at the nodes. Spread of the species by seed is unlikely as flowering is uncommon and sparse. The climate on Raoul Island is probably too cool for seed to set, and marginal for flower initiation (Skerman and Riveros 1990 in West 1996).
