Sixty new or updated records of plant species are reported from the Sultanate of Oman, as a result of field work and herbarium research. Four taxa represent new records for Arabia, 26 are new records for Oman, and 30 represent an extended distribution within Oman. Some previously doubtful records are confirmed.
