Samuel Frederick Gray

Samuel Frederick Gray (10 December 1766 – 12 April 1828) was a British botanist, mycologist, and pharmacologist.

He received no inheritance and, after failing to qualify for medicine, turned to medical and botanical writing.

Gray's major text of interest today is The Natural Arrangement of British Plants, published in two volumes in 1821.

[3][4] The authorship is disputed, and his son, John Edward Gray, later claimed to have done most of the work, but that was not supported by his grandson.

[1] The Natural Arrangement of British Plants also included substantial sections on fungi, then classed as cryptogamic plants, introducing many new genera, including Auriscalpium, Coltricia, Leccinum, and Steccherinum, which remain in current use.
