Dear Colleagues: I am trying to find the *origin of the word* "tacamaca" or "tacamahaca". In a 16th century document, a tree, tacama(ha)ca, whose scientific name is *Populus balsamifera* L., is mentioned. As far, as I have been able to find, the word comes from the Nahuatl. http://www.dictionary.com/browse/tacamahac . If you happen to have a more detailed origin for the word, please send me an email to
