Am y BSBI

Mae'r BSBI ar gyfer pawb sydd â diddordeb yn fflora Prydain ac Iwerddon. Rydyn ni'n tarddu'n ôl i 1836, pan sefydlwyd y Gymdeithas fel Cymdeithas Fotaneg Llundain. Rydyn ni bellach yn un o gyfranwyr mwyaf y byd o ran cofnodion biolegol: mae ein data ni'n sail i ymchwil wyddonol ac i gadwraeth sy'n seiliedig ar dystiolaeth yn ein hoes.
