The University of British Columbia Herbarium is the largest in Canada west of Ottawa, and is home to over half a million plant specimens from around the world. This collection is critical to the identification, monitoring, and conservation of plant biodiversity in British Columbia, and is an important resource for education and scientific research. The UBC Herbarium has five major collections: vascular plants (flowering plants, conifers, ferns, and their relatives); bryophytes (mosses, liverworts and hornworts); macroscopic algae (mostly seaweeds); lichens; and fungi. In addition to the world's largest collection of BC plants, our internationally recognized bryophyte collection is the largest in Canada. We also have important collections of Pacific algae, fungi, Hawaiian plants and tropical prayer plants.
