The Paul L. Hollister Herbarium at TN Tech 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 TN Tech. We actively participate in locating and documenting state and federal listed threatened and endangered species. We are also a resource for the community, offering tours and other educational opportunities.

HTTU is part of the Tennessee Herbarium Consortium  and actively contributes our specimen data to the Southeast Regional Network of Expertise and Collections (SERNEC). You can search our databased and imaged specimens by clicking here: HTTU Herbarium Database.
