    Description
    Botanical study of marine algae Carpophyllum plumosum, referred to here as Sargassum plumosum. Depicts two specimens with flat fronds growing off the main stem, on a pale cyanotype leaf.

    Captioned below ‘Sargassum plumosum’ in a photographic facsimile of the author’s handwriting.

    Blueprint from Photographs of British algae: cyanotype impressions, by Anna Atkins (London, 1843-1853).

    Anna Atkins (1799-1871) was a British botanist, plant-collector and photographer.
    Object history
    The original purpose of Anna Atkins’ Photographs of British Algae was to provide illustration for William Harvey’s FRS (1811-1866) A manual of British marine algae (1841). It was privately printed by Atkins and is considered the first scientific manual to be printed using photography to replace conventional means of illustration.

    Photographs of British Algae was issued as a part book to various scientific institutions, and Atkins made fifteen part donations to the Royal Society between October 1843 and the end of 1853. It was up to the Royal Society to bind the cyanotypes according to Atkins' instructions. The final result is a 3 volume series containing 425 plates, and an additional gathering of 7 plates, which were never incorporated.

    ‘Carpophyllum plumosum’ is one of these additional 7 plates. There is no indication in any of the tables of contents or appendices of the three volumes of Photographs of British Algae as to where this plate was intended to appear.
