This is a new species to me. I have only seen it at Jenkins Arboretum in southeast Pennsylvania, and with a label. There is a colony of the Broad Beech Fern next to its colony and it seems that the latter species has done some invasion into the Blunt-lobed colony. The Blunt-lobed Cliff Fern species has lacy, narrowly oblong grayish-green or light green fronds with glands and hair on each side of the leaves. The secondary leaves (pinnae) are nearly opposite and widely spaced. The leaflets are blunt-lobed. The sori under the leaves are round with ragged indusia that surround the sori. it is native to southeast Canada down into Florida to east Texas up through eastern Nebraska & Kansas through Minnesota. It grows in moist to dryish, neutral to slightly alkaline soils mostly on cliffs, ledges, and slopes. This is a pretty, low-growing, spreading fern. I've never seen it sold at any nursery, but there are some online specialty nurseries that sell it. The generic name of Woodsia comes from the name of Joseph Woods who was an architect and botanical author of the late 18th century to the mid-19th century.
