Johnson's Shut-Ins Dolomite Glade
A 4-acre dolomite glade of the Davis rock formation located on a forested southwest-facing slope. Dolomite glades are rare in the St. Francois Mountains. This is the only dolomite glade represented from the St. Francois Mountains Section of the Ozark Natural Division. The glade was part of a floristic study conducted at Johnson's Shut-Ins State Park in 1977 by Paul Nelson. Several plants noted only on the glade, which contribute to the park's 900 plant species, include Missouri evening primrose, Englemann's adder's tongue fern and sandwort.
Missouri Primrose (Oenothera missouriensis)
Adder's Tongue (Ophioglossum engelmanni)
