One carton of material was given in 1955-1956 by Mrs. Nina Floy Bracelin, from the Ynis Mexma Estate. Additional items were
a gift from Mrs. William E. Colby in 1962. The bulk of the collection came from Mrs. Bracelin in 1963.
Ynés Mexía was born May 24, 1870 in Georgetown, Washington, D.C., where her father, General Enrique A. Mexía, was serving
as a representative of the Mexican government under President Porfirio Díaz. Her grandfather, José Antonio Mexía, was also
a Mexican general, serving under President Antonio López de Santa Anna. Her mother, Sarah R. Wilmer of Maryland, was a descendent
of Samuel Eccleston, Fifth Archbishop of Baltimore. Ynés Mexía spent her early childhood in Texas on a land grant where the
town of Mexía, Limestone County, is now located. She attended private schools in Philadelphia and Ontario, Canada; St. Joseph's
College, Emmetsburg, Maryland; and the University of California, Berkeley. As a young woman she lived in Tacubaya, Mexico,
where she married Herman E. Laue in 1898. After his death, she married Agustín Reygadas. This second marriage ended in a divorce.
Her first collecting expedition was to Mexico in 1922, as a member of a group led by E. L. Furlong, Curator of Paleontology,
University of California, Berkeley. The important collecting began in 1925 on her second trip to Mexico, with Mrs. Roxana
S. Ferris, Dudley Herbarium, Stanford University. On subsequent collecting expeditions she went three more times to Mexico,
once to Alaska, and twice to South America. She collected for the University of California and the United States Department
of Agriculture. One trip to South America, lasting two and a half years, was initiated by her, and included a trip down the
Amazon.
Her contributions to botany included a total of 8,800 numbers. She collected approximately 145,000 specimens. Two were new
genera,
Mexianthus mexicanus Robinson (Compositae) and
Spulula quadrifida Mains (Pucciniaceae). The collections included approximately five hundred new species, primarily spermatophytes. Fifty species were named after
her. Her plants were widely distributed and are now in leading botanical museums in the United States and Western Europe.
She was a member of the Sierra Club, California Botanical Society, Audubon Association of the Pacific, California Academy
of Sciences, Sociedad Geografica de Lima, Peru, and an honorary member of the Departamento Forestal de Caza y Pesca of Mexico.
In 1951, part of the remainder of her estate was given to the Save-the-Redwoods League, which purchased land in Northern California,
west of Prairie Creek, containing a beach and Home Creek Canyon.
In 1938, during a collecting trip in the mountains of the State of Oaxaca, Mexico, she became ill. She returned to San Francisco
in May, and died on July 12, 1938, at the age of 68.
The Ynés Mexía Papers reflect the outstanding contributions of this botanist, explorer and collector, who began her most important
work late in her life, when she was past 50 years old. Her 15-year career of plant collecting for the University of California,
United States Department of Agriculture, and herself took her on five expeditions to Mexico, two to South America, and one
to Alaska. The botanical researcher will be impressed by the detailed scientific record left by Ynés Mexía.
In the General Correspondence (Series 1) there are personal letters and letters written to Nina Floy Bracelin, who was her
close associate. Some correspondence to and from Mexico is in Spanish. The letters from the field to Bracelin are fascinating
accounts of her experiences, and a few from South America were passed among friends and colleagues. Other correspondence regarding
botanical collections is found elsewhere in the collection (Series 4). The letters to botanical institutions and to other
botanists include Bracelin correspondence, written while she was acting in her capacity as an assistant to Mexía.
Series 2, Biographical Information, contains personal financial records, family history materials, newsclippings concerning
Mexía's botanical expeditions, and obituaries. Writings relating to her travels and plants, travel, lecture and natural history
notes, as well as articles which cite Mexía, are found in Series 3.
Notebooks compiled by Mrs. Bracelin containing determination and distribution lists relating to plant collections (Series
5), and card file boxes containing labels for numerical and family sets of botanical species (Series 6) are present also.
Annotated maps used during botanical expeditions are included in Series 7. Photographs of plants taken by Ynés Mexía have
been separated and placed with the Pictorial Collections.
