Flowering plants, grasses, rushes, sedges and ferns and stoneworts
Records of vascular flora (flowering plants, grasses, rushes, sedges and ferns) and charophytes (stoneworts) are kept in the OHBR database and then forwarded annually to the county recorder to be checked before being submitted to the NBN database via the Botanical Society of Great Britain and Ireland. The flora of the Outer Hebrides is comparatively well recorded, although many of the records are old. A number of local recorders are involved in botanical recording and are contributing records for the next edition of the Atlas of the British Flora.
Algae & Bryophytes
Records of freshwater algae and seaweeds form part fo the OHBR database and appear on the NBN Gateway. Records of bryophytes (mosses and liverworts) are also included in the OHBR database and are forwarded to the county recorder to be checked before being submitted to the NBN database via the British Bryological Society. There are photographs of a small number of mosses and liverworts on the Outer Hebrides Bryophytes website. The site includes photographs of the microscopic characters but not distribution maps.
