SERNEC (SouthEast Regional Network of Expertise and Collections) is a consortium of 233 herbaria in 14 states in the southeastern USA. Our aim is to provide herbarium specimen images and metadata from one of the most botanically diverse regions of the earth with the goal of facilitating research, management planning and a well-informed public. These data span 200 years of botanical information housed in herbaria in the Southeast and are vital to studies in biodiversity, evolution, ecology and systematics to name a few.
