He was unable to include her illustrations in this publication, but she eventually contributed her artwork to the NYBG journal, Addisonia.At Britton's death in 1934, Flora Borinquena was left unfinished though Mrs. Horne had completed over 700 watercolors of native and naturalized Puerto Rican plant species for the work.In 1963, Mrs. Horne presented her collection as a gift to the NYBG. She also painted the Caribbean bird life and contributed illustrations to Common Trees of Puerto Rico and the Virgin Islands (1967) by Elbert Little, Frank Wadsworth, and Jose Marrero.She died at the age of 94 in Albany, New York.Source:"Frances W.
