"The writer [Mueller] selected this plant, one of the most interesting of those of the Chatham-Islands, for bearing the name of the Honorable Dr. Featherstone, Government Superintendent at Wellington, New Zealand, as a mark of recognition of the favor shown by that able officer in introducing some years since a number of living plants from the Chatham-Islands into the Melbourne Botanic Garden."
