 Ex @-@ situ conservation efforts to propagate A. brownii by seed in botanical gardens have been unsuccessful . During the 1981 expedition , A. bronwii seeds were collected by Sheila Conant and presented to the Waimea Arboretum on the Hawaiian island of Oahu and the Kew Gardens in London , England . Although the seeds at the Waimea Arboretum germinated and grew for a while , no plants survived beyond the stage of seedling development . Information about the outcome of the seeds sent to Kew Gardens is unavailable .
