The Function of the Herbarium
The Brunei National Herbarium (BRUN) is the main herbarium in Brunei Darussalam and plays an important role as the centre for specimens collected in the country as well as specimens from the neighboring countries Sabah, Sarawak, West Malaysia, Kalimantan, Indonesia and Singapore. BRUN is also actively sending duplicate specimens to major herbaria such as Kew Botanic Gardens (K) and Leiden (L), and some regional herbaria such as Kuching (SAR), Sandakan (SAN), FRIM, Kepong (KEP) and Singapore Botanic Gardens (SING).
The Herbarium Collections
Botanical collections are carried out regularly and at present, BRUN is set for the 21st Century. It has a comprehensive database, part of which is available on the Internet through the Kew Gardens website. Cataloguing is now computerized, and electronic image storing is now computerized. The five years (1990-1995) collaboration project between the Forestry Department of Brunei Darussalam and Royal Botanical Gardens, Kew was successfully produced A Checklist of Flowering Plants and Gymnosperms of Brunei Darussalam.
The herbarium specimens are also arranged in alphabetical order of families, genera and species, this would make reference easier for all users. Currently, BRUN houses more than 29,000 dry specimen collections, and the herbarium is laid out into 3 blocks comprising of bryophytes and pteridophytes collection in Block A, dicotyledons collection in Block B, and monocotyledons collection in Block C. The dicotyledons collection is placed in compactor cabinet system, whilst the others are placed in steel cabinets.
BRUN is an important reference centre in the country. Researchers from other parts of the world, chiefly those attached to the Universiti Brunei Darussalam, often visit BRUN.
Type Collection
Type specimens for new species described from Brunei are of taxonomic importance. All type specimens are carefully kept in special folders (red folders) in a separate room. Currently, there are 101 type specimens kept at BRUN, and mostly are isotypes, of which 91 types described were from Brunei Darussalam and others were collected from Sabah and Sarawak.
Other Collections
BRUN also houses a large collection of slide photographs for the various plant species. Carpological collections are also maintained, but currently, they are rather limited and need to be expanded in the future. Apart from the dried specimens, BRUN is also developing ex-situ planting areas for living specimens, such as the orchid, bamboo and palm collections.
