385 of which represent 118 types. Three appendices provide: a) a list of known Fontinalaceae types in the Welch Herbarium;
b) a list of collectors of Fontinalaceae whose collections were studied by Welch after the publication of her monograph in
1960; and c) a list of Welch's collecting trips outside of Indiana.
