Biographical Note

Botanical collector and explorer Ynes Enriquetta Julietta Mexia was born on May 24, 1870, in Georgetown, D. C to General Enrique A. and Sarah R. (Wilmer) Mexia. She spent much of her childhood in Limestone County, Texas.  She attended private schools in Philadelphia and Ontario, California and St. Joseph’s College in Maryland.

After taking a Flowering Plants class with LeRoy Abrams at the Hopkins Marine Station in 1925, Mexia accompanied Stanford botanist Roxana Ferris on a botanical collecting trip to western Mexico. Over the next thirteen years she made three additional expeditions to Mexico as well as visiting Alaska and South America, visiting many remote areas. She collected for the University of California and the Untied States Department of Agriculture and visited many remote areas, collecting 8800 numbers and approximately 145,000 individual specimens, 500 of which were found to be new species. Her specimens were often prepared by her assistant, Mrs. N. Floy Bracelin at the University of California, Berkeley and sets were distributed widely to herbaria in the United States and Western Europe.  In addition to the specimens, she wrote numerous articles detailed her adventures exploring the Amazon and other remote areas.
