The ROM Vascular Plant Herbarium is known by its acronym, TRT (Holmgren et al. 1990). TRT is located in the ROM Center for Biodiversity and Conservation Biology at 14 Queen's Park Crescent W, in Toronto. TRT is a collection of over 260,000 specimens and associated photographic and other material that primarily documents the flora of Ontario. The makeup of the TRT collections was described by Boivin (1980). Since that time there have been some notable additions made to the collection. Manitoba, Ontario, and Siberian plants were received from J. C. Ritchie of Scarborough College. Graduate student activity (both thesis and non-thesis related) in the 1980's led to deposit of important collections (e.g. plants of northern Ontario). As a result of these and other activities, TRT is now the fifth largest vascular plant collection in Canada, after Québec (QFA), Ottawa (CAN, DAO), and Montréal (MT). It is thus a major source of Canadian plants, and probably has the best collection of Ontario material in the world.

TRT also serves as a depository for voucher specimens of Canadian and other plants from a wide range of research projects at the ROM and the University of Toronto. Research activity in Botany at the ROM is resulting in improved TRT coverage of Rosaceae subfamily Maloideae (studies by T. A. Dickinson, students, and collaborators) and of the flora of Grenada (studies by J. H. McAndrews and K. Barbour, students, and collaborators at the University of the West Indies, St. Augustine, Trinidad; Barbour & McAndrews 1995).

Public service activity includes not only support for regional Ontario floristic projects (such as this page), but also plant identifications, particularly in response to calls referred by the Poison Control Center at the Hospital for Sick Children in Toronto (Metsger 1990).
