 Although R. K. Greville published his "Algae Britannicae" as early as 1830, it was not until 1902 with the publication of "A Catalogue of the British Marine Algae" by Edward Arthur Lionel Batters that the systematic correlation of records, extensive distribution mapping and the development of identification keys began in earnest.In 1899-1900, Anna Weber-Van Bosse, a Dutch Phycologist travelled on the Siboga expedition and later in 1904, published "The Corallinaceae of the Siboga-expedition".As early as 1803 Jean Pierre Étienne Vaucher had published on the isogamy (sexual conjugation) in the algae, but it was in the early 20th century that reproduction and development began to be extensively studied.
