=== ''Ageratum conyzoides'' ===
''[[Ageratum conyzoides]]'', also known as billygoat-weed, chick weed, goatweed, or whiteweed, is native to the tropical Americas, and was found in Hawaii by [[William Hillebrand]] in 1888 who considered it to have grown there before [[James Cook|Captain Cook's]] arrival in 1778. A legitimate native name (''meie parari'' or ''mei rore'') and established native medicinal usage and use as a scent and in [[Lei (garland)|leis]] have been offered as support for the pre-Cookian age.<ref>{{cite book |last1=Hillebrand |first1=William |title=Flora of the Hawaiian Islands |url=https://archive.org/details/mobot31753003034128 |date=1888 |publisher=Williams and Norgate |location=London}}</ref><ref>{{cite journal |last1=Brown |first1=Forest B.
