Observation Time: 9:40 a.m.

Observation Location: Town conservation land near Beaver Brook

Common Name: Cinnamon Fern

Scientific Name: Osmundastrum cinnamomeum

Comments: The Osmundastrum cinnamomeum fern forms huge clonal colonies in swampy areas. These ferns form massive rootstocks with densely matted, wiry roots. This root mass is an excellent substrate for many epiphytal plants. They are often harvested as osmunda fiber and used horticulturally, especially in propagating and growing orchids. Cinnamon Ferns do not actually produce cinnamon; they are named for the color of the fertile fronds.

Observation Location: Moose Hill Audubon Wildlife Sanctuary

Common Name: Hay-scented Fern

Scientific Name: Dennstaedtia punctilobula

Comments: Hay-scented fern is very common in Sharon. It is often found growing in large colonies, forming a green carpet on the forest floor. It can be identified by its lacy, light-green fronds. It can be confused with New York fern, but hay-scented fern has triangular fronds, whereas New York fern fronds taper to tiny leaflets at the bottom.

Common Name: Sensitive Fern
