She is known to have worked with Elizabeth Gertrude Britton, Nathaniel Lord Britton, and Joseph Edward Little, as co-collectors of specimens. One expedition with Elizabeth and Nathaniel Britton, to Puerto Rico, was undertaken in January 1922, with a planned duration of ten weeks. The results of that expedition were presented in April of that year.
