Eastern Inner Loop

Joel McNeal
This plant, Pellaea atropurpurea (L.) Link (commonly called purple cliffbrake), occasionally grows in calcareous cliffs and ledges or in old masonry walls. In the arboretum's floristic survey, it was found growing on a hilltop, in a conifer forest that supports the richest assemblage of native plants in the arboretum (129 species).

The Arboretum will be a place of beauty, an important cultural feature of the University and the community.
