The Herbarium of the University of Puerto Rico at Rio Piedras (UPRRP) was founded in 1966 and is a repository of preserved mycological, algal, and plant specimens of Puerto Rico and the Caribbean. Most of the holdings are vascular plants of Puerto Rico, but active collecting by faculty, staff, and students, coupled with an aggressive exchange program, enhance the representation of other islands of the Caribbean. The herbarium holds approximately 45,000 accessioned specimens.
UPRRP is currently hosting several major projects. We are in the process
of entering all specimen data in a Brahms database and digitizing all species
in our collection. These will soon become available on-line. Dr. Frankin
Axelrod has completed a systematic vademecum to the vascular plants of
Puerto Rico which updates and expands the synoptic flora providing more
detailed ecological data and taxonomic commentary. Three other floristic
projects are based at UPRRP and these include the Orchidaceae treatment
for the Flora of the Greater Antilles by Dr. James Ackerman, the Mona Island
biodiversity project of Dr. Elvia Meléndez-Ackerman, and the floristic
studies of St. Lucia by Roger Graveson.
