Leaded by Commodore Perry, the US Japan Expedition of 1852-54 ("Perry Expedition") had a mission to initiate open trade with
Japan. Multiple previous attempts (4 American and 14 international expeditions) had failed to initiate trade. Perry succeeded
to sign the treaty. The other goal of the expedition was gathering information on natural history. Rev. S. Wells Williams
and Dr. James Morrow were appointed plant collectors and brought back both dried samples and live plants. A list of plants
collected in Japan was then compiled by Asa Gray, who described a new species of honeysuckle from Japan and named it after
its collector. The plant later on became the most aggressive of naturalized exotic shrubby honeysuckles, all of which ended
up on the invasive plant list.
