A collaborative project of the Missouri Botanical Garden, Pontificia Universidad Catolica del Ecuador, the Museo Ecuatoriano de Ciencias Naturales, and Aarhus University, this Internet version of the _Catalogue of the Vascular Plants of Ecuador_ "is designed to give users an overview of the plant species found in Ecuador and allows them to easily navigate and browse the information currently available." The _Catalogue_ "documents 15,901 plant species known to occur in Ecuador" and the site's Search Engine allows users to access data by scientific name or by using either the index to accepted names or the index to all names. This fantastic site also includes links to relevant information about Ecuador such as Geography, Paleoclimates, Vegetation, and History of Collecting. The website is available in Spanish as well as English.
