The Paul L. Hollister Herbarium at TTU is involved in education, research, and conservation. We acquire and maintain a collection of pressed and mounted plant specimens with emphasis on the flora of the Cumberland Plateau and to a lesser extent the flora of southeastern United States.
The herbarium provides resources for those interested in botany, ecology, floristics, ethnobotany, systematics, and wetland management. The herbarium supports both undergraduate and graduate research in botany at TTU. We actively participate in locating and documenting state and federal listed threatened and endangered species. We are also a resource for the community, offering wildflower walks and other educational opportunities.
