As Hispanic Heritage month wraps up, we want to highlight Helia Bravo Hollis 🏵️
She grew up in Villa de Mixcoac outside Mexico City, a contemporary and classmate of Frida Kahlo. Her Sunday walks with her parents inspired her to study living beings and led to her passion of studying cacti in adulthood.
Helia was a pioneer in her field, becoming:
🌵 The first certified biologist in Mexico in 1927
🌵 Founding president of the Mexican Society of Cactology
🌵 The director of the botanical garden at UNAM for over 3 decades until her retirement at age 90
🌵 Published in 170 articles & the author of 3 books
Today, the desert section of the Botanical Garden at UNAM is named for her, as well as the Helia Bravo Hollis Botanical Garden in Puebla, which is home to many endangered cactus species. The species Opuntia bravoana plus the genus Heliabravoa were named in her honor.
Opuntia bravoana blooms a vibrant yellow flower and bears the prickly pear fruit (tuna) that may sometimes color your drink a bright fuschia. It's paddle-shaped stem bears short spines and grows outwards into a shrubby plant, and you can find it growing across most of the United States.
Bravo Hollis' impact reverberates across the Americas, including the United States.
