Charles James Sprague (January 16, 1823, Boston – August 5, 1903, Hingham, Massachusetts) was a bank official, author, poet, musician, and botanist, specializing in lichenology.
He was an intimate friend of the late Dr. Asa Gray, to whose collections he contributed many valuable specimens and critical notes.
Like the late Edwin Faxon, Mr. Sprague was more anxious to aid others in their investigations than to publish the results of his own patient and critical observations.
His valuable collection ... has for some time been property of the Boston Society of Natural History.
[4] In 1856 Charles J. Sprague was elected a fellow of the American Academy of Arts and Sciences.
