The UPRRP Herbarium

The UPRRP Herbarium is a repository of preserved vascular plants, bryophytes, algae and fungi that are available for studies in taxonomy, systematics, natural history, ecology, biogeography, genetics, ethnobotany, and other topics. Not only do we have an excellent representation of the flora of Puerto Rico, we also have numerous specimens from many other islands of the Caribbean Basin.  The UPRRP Herbarium is presently amongst the most active in the Caribbean with current holdings of over 54,000 specimens, most of which are vascular plants. We also have a small library that meets most needs for the identification of Caribbean plants.

Aside from institutional consultations and every day use of collections and facilities, UPRRP receives and assists visitors who use our facilities and consult our collections for their research projects, teaching projects or scientific curiosity.

UPRRP is operated by the Department of Biology, College of Natural Sciences of the University of Puerto Rico, Río Piedras campus.
