Disclaimer: The Field Museum's online Botanical Collections Database may contain specimens and historical records that are culturally sensitive. Some records may also include offensive language. These records do not reflect the Field Museum’s current viewpoint but rather the social attitudes and circumstances of the time period when specimens were collected or cataloged.
We welcome feedback. The web database is not a complete record of the Museum’s botanical holdings, and documentation for specimens will vary due to when and how they were collected as well as how recently they were acquired. While efforts are made to ensure the accuracy of the information available on this website, some content may contain errors. We work with communities and stakeholders around the world to interpret the collections in order to promote a greater understanding of global heritage and, through consultation, will revise or remove information that is inaccurate or inappropriate.
