ARIZ Plant Identification Services
As a Land Grant Institution, an important part of the mission of the University of Arizona is to serve the public.
In keeping with this mission, the University of Arizona Herbarium provides plant identification services free of charge to researchers from non-profit and public sector institutions, government organizations at all levels, and the general public. For-profit organizations that wish to use our services are requested to make a donation of $50 per hour to the University of Arizona Foundation: Herbarium Discretionary Account. This fund is used to improve the herbarium and its ability to serve the public.
Bear in mind that we receive more plant identification requests than our staff can handle. Depending on our work load at the time, and in particular if the number of specimens is large or if the identifications will be particularly time-consuming, we may choose to assist you in identifying the plants yourself by directing you to the appropriate identification resources (taxonomic literature, herbarium specimens) and/or providing partial determinations to family or genus.
In general we do not provide identifications to students making required plants collections for courses; we will however provide guidance in the use of our collection and literature resources for those wishing to identify their plants here at the herbarium.
The main focus of our specimen collection and taxonomic literature is the native and naturalized plants of Arizona and northwestern Mexico, and to a lesser extent the rest of North, Central and South America. Therefore in general we do not identify cultivated plants, which can come from anywhere in the world. In some cases, however, we may be able to assist you if the cultivated plant is also native to one of our focal regions.
