Throughout its history, the Botanical Institute of Barcelona (IBB) has acquired a variety of herbaria dating from the 17th to early 20th centuries, as a continuation to the significant initiatives already undertaken by its founder Pius Font i Quer. These collections are separately preserved from the general herbarium and ordered according to original author. These collections are the following:
|Collections||Època||Nombre de plecs|
|Ruiz & Pavón||18th||698|
|Societat Botànica Barcelonesa||19th||1.213|
|Hieraciotheca Gallica et Hispanica||19th-20th||2,108|
|Institució Catalana d’Història Natural||19th-20th||1,202|
In her doctoral thesis, Dr. Neus Ibáñez studied five of these historical herbaria: Salvador family, Ruiz & Pavón, Bernades, Societat Botànica Barcelonesa and Institució Catalana d’Història Natural. Currently these collections are being studied within the Collections, Flora and Vegetation research group.
The number of specimens for 6 collections (marked with an asterisk) is estimated, as these have not been fully catalogued.
