The Marie-Victorin Herbarium (MT) is the second largest university herbarium in Quebec, and ranks fourth among all Canadian herbaria. It includes about 680,000+ vascular plants. Half of the material is Canadian, but representation is global. Recently, the WAT herbarium was acquired and is now incorporated within MT, though specimens are still to be cited with the WAT acronym. The MT and WAT datasets are individually shown in the dataset, though they all belong to MT. The current dataset includes the 164,000+ digitized specimens from the collection.
