Online Collections Data

SEINet - The Southwest Environmental Information Network, hosted by the Global Institute for Sustainability, Arizona State University
Users can search one or many of the ASU collections databases, generating maps and checklists. We have spent years perfecting this interface and adding new features. Interactive plant keys are also available for some regions of Arizona as are photos of many specimens and plants.
