Clarence Bicknell (1842-17 July 1918) was a British amateur botanist and archaeologist.
While employed as a vicar in Bordighera, Italy[1], Bicknell became noted for his identification of the plants and petroglyphs of the Ligurian Riviera. Bicknell's notable writings include Flowering Plants of the Riviera and Neighboring Mountains (1885)[2] and Guide to the Prehistoric Rock Engravings of the Italian Maritime Alps (1913).[3] His extensive collection of specimens and illustrations were archived in the Museo Biblioteca Clarence Bicknell in Bordighera and at the University of Genoa.[3]
