The total Australian National Herbarium (ANH) collection (Canberra [CANB] and Atherton [QRS]) comprises approximately 1.4 million specimens, including about 8251 type specimens. Particularly comprehensive collections are held for Australasian bryophytes and lichens, Myrtaceae (especially Eucalyptus and Melaleuca-Callistemon), Orchidaceae, Sapindaceae, Lauraceae, Portulacaceae and some sections of Poaceae, Rutaceae, Proteaceae and Fabaceae. A strong representation of Papua New Guinean material derives from past CSIRO involvement in that area and a comprehensive specialist collection of tropical Australian rain forest species is held at Atherton (>100 000 collections). Voucher material for the Australian National Botanic Gardens (ANBG) Living Collections and the ANBG Photographic Collection is clearly identified and accessible; the status of associated live material at ANBG, representing c. one third of the Australian vascular flora, is available on-line (http://www.anbg.gov.au/anbg/plant-records/search-lc-vic.html
). The existence of properly vouchered herbarium specimens for ANBG's live plants is critical for the scientific integrity and ongoing usefulness of scientific studies using those plants (e.g. for DNA extracts).
