In the vast expanse of Big Bend National Park, a remarkable botanical discovery has unfolded—a new plant genus and species, Ovicula biradiata, affectionately known as the “wooly devil.” This finding marks the first identification of a new plant genus in a U.S. national park in nearly half a century, shedding light on the rich biodiversity that thrives in the Chihuahuan Desert.

Discovery Amidst the Desert
The journey began in March 2024 when Debra L. Manley, a dedicated botanist volunteering at Big Bend National Park, stumbled upon an unusual plant in the park’s remote northern reaches. Its fuzzy white foliage and distinctive red ray florets immediately set it apart from known species. Recognizing its potential significance, Manley documented the plant and shared her observations on the community science platform iNaturalist, seeking insights from the broader botanical community.
Scientific Collaboration and Identification
The plant’s unique features puzzled experts, prompting a deeper investigation. A collaborative effort ensued, involving scientists from the California Academy of Sciences, Big Bend National Park, Sul Ross State University, and the Centro Interdisciplinario de Investigación para el Desarrollo Integral Regional (CIDIIR). Through meticulous research, including genetic sequencing, they confirmed that this plant represented not just a new species but an entirely new genus within the sunflower family (Asteraceae).
Characteristics of the Wooly Devil
Ovicula biradiata is a small annual plant, measuring between 1 to 3 inches in height and 1 to 7 inches in width. Its dense, wool-like hairs cover its leaves and stems, giving it a distinctive fuzzy appearance. The name “Ovicula” is derived from the Latin word for sheep, alluding to its woolly texture, while “biradiata” refers to its two prominent ray florets that resemble devilish horns. These unique floral structures contribute to its common name and highlight its distinctiveness within the sunflower family.
Ecological Niche and Adaptations
The wooly devil thrives in the harsh, rocky soils of the Chihuahuan Desert, particularly in limestone pediments. It is an ephemeral species, blooming only after rainfall—a strategy common among desert annuals to maximize reproductive success during favorable conditions. This adaptation underscores the resilience and adaptability of desert flora. However, this specialized habitat preference also renders it vulnerable to environmental changes, particularly those induced by climate change.
Conservation Concerns
Given its recent discovery and limited known distribution, Ovicula biradiata has been preliminarily classified as “vulnerable.” The exact locations of its populations are deliberately undisclosed to protect them from potential disturbances. The increasing frequency of droughts and temperature extremes poses significant threats to its survival. Researchers emphasize the urgency of studying this species further to develop effective conservation strategies and mitigate the risks posed by a changing climate.
Implications for Botanical Research
The discovery of the wooly devil after nearly five decades since the last new plant genus was identified in a U.S. national park (Dedeckera eurekensis in Death Valley, 1976) highlights the vastness of botanical diversity yet to be explored. It underscores the importance of continuous field research and the role of community science platforms like iNaturalist in facilitating discoveries. This finding also prompts a reevaluation of conservation priorities, especially in underexplored and extreme environments like deserts, where unique species may be awaiting discovery.
Potential Medicinal Properties
Interestingly, researchers have observed specific glands on the wooly devil that are known to possess compounds with anti-cancer and anti-inflammatory properties in other plants within the sunflower family. While further research is needed to determine these properties, this discovery underscores the potential knowledge we stand to gain from preserving plant diversity in fragile desert ecosystems.
Engaging the Public
The story of Ovicula biradiata serves as an inspiring example of how individuals can contribute to scientific knowledge. Manley’s initial observation, coupled with the collaborative efforts that followed, showcases the power of curiosity and community engagement in advancing science. Public involvement is crucial in monitoring and conserving such species, ensuring that discoveries like the wooly devil continue to enrich our understanding of biodiversity.
Conclusion
The discovery of the wooly devil in Big Bend National Park is a testament to nature’s enduring mysteries and the continuous potential for discovery within our protected lands. It highlights the importance of preserving these natural habitats, not only for the species we know but also for those yet to be discovered. As we face global environmental challenges, such findings remind us of the intricate and delicate web of life that thrives, often unnoticed, around us.
