Sultan Qaboos University Herbarium (SQUH) houses a collection of approximately 6,000 specimens. The majority of the specimens are preserved as dried sheets. In addition, spirit collection is also kept primarily for the succulent species. The herbarium focuses mainly on Oman’s native species. However, as part of an initial exchange program some records were received from some neighboring herbaria. Future plans intend to develop the exchange agreement and establish new botanical connection within the Arabian region. This should upgrade SQUH to a Regional level, which would enrich the scientific value of the collection and allow more insights on the study of phylogenetics and evolutionary relationships of the plants in this part of the world. The collection is organized alphabetically by family, genus and species, respectively. The collection includes Algae, Ferns, Gymnosperms and Angiosperms (dicots and monocots). The specimen collection was built up from staff collections over the years. The herbarium also accepts specimens from scientific researches, government organizations, consultancy organizations and general public as long as they fulfill requirements as voucher specimens.
Authentication by specialists
The identification of plants is undertaken by the herbarium staff using appropriate identification resources such as taxonomic literature and cross checking with already determined voucher specimens. Some difficult groups are sent for proper determination or confirmation by specialists in other International Institutes. Alternatively, some groups are sent on loan for taxonomic revision. After revision, updates on the taxonomic status of the specimens are expected in return.
Revised collections are:
Poaceae (genus Sporobolus) seen by Dr. T. Cope, Royal Botanic Gardens, Kew
Asteraceae (genus Launaea) seen by Dr. N. kilian, Botanic garden & Botanical Museum Berlin-Dahlem
Cyperaceae seen by Lorna Mackinnon, the Royal Botanic Gardens, Edinburgh
Computerized database
A total of 5901 specimens, comprising more than 90% of all collection, are entered in a computerized database. The database is searchable by family, genus and species, where a specimen list is produced with collector’s name & number, collection locality and date of collection. Where available, some accessions contain images of the specimens in the field (before drying ).
