Phelps, Henry, 1766-1852. Botanical Memorandum of Henry Phelps, 1790. B MS Misc., Countway Library of Medicine.

Diary entries containing observations on and properties of local wildflowers, presumably near Gloucester, Massachusetts, written by Dr. Henry Phelps (1766-1852). The entry on geranium maculatum notes that particular plant is "powerfully astringent," and when used in conjunction with the plant limonium as a gargle, "is a good medicine in inflamed, ulcerate sore throats."
