Botany Collection

The National Herbarium of Canada

A Brief Herbarium History

The National Herbarium of the Canadian Museum of Nature has grown from lengthy and auspicious roots. The plant collections of the Geological and Natural History Survey of Canada were officially incorporated into a museum department in 1882.

At that time John Macoun was hired as the museum's first biologist; his primary interest was botany. Macoun built up a sizable collection of approximately 100 000 plants, known as a herbarium, before his semi-retirement in 1911. As a result of Macoun's collecting and trading endeavours, the museum's Plant Collections are rich in historic specimens dating back to 1766.

A.E. Porsild was hired as the museum's botanist in 1936, and with his specific interest in Arctic botany, he developed the Canadian National Herbarium into a world-class Arctic plant collection that today holds more than 100 000 Arctic plant specimens.

In 1968 the Canadian National Herbarium was divided into four separate herbaria, each with its own international code: vascular plants (CAN); algae (CANA); Lichens (CANL) and Bryophytes (CANM). Today, the museum's four herbaria together contain more than one million plant specimens.
