Appalachian Cliff Saxifrage 

Saxifrage michauxii ( biosyn: Micranthes petiolaris )

Through out the rocky splash cliff communities in Appalachia grows the unique appalachian endemic cliff saxifrage, if you find this species there is a chance that other prostrate and or densely pubescent hydrophilic cliff dwelling species are also assembled there.   

Common assemblages- 

Round leaf drosera, film mosses, rock cliff mosses,

brook saxifrage, Oconee saxifrage, hornworts, many liverworts, 

small-flowered alumroot, palmate false saxifrage, rock club mosses, lithophytic ferns, cliff foam flower, violets, 

enchanter’s night-shade, meadow rue, mountain meadow rue, drooping sod, and many others.
