Scapania nemorosa


Formerly known as Scapania nemorea (L.) Grolle, Scapania nemorosa is a common leafy-liverwort in New Brunswick. It is recognized by its complicate-bilobed leaf patterns (with long ventral lobes and short, decurrent dorsal lobes), spinose leaf margins, and clusters of red, angular gemmae on leaf tips. The stems are typically green, but are sometimes tinged with dark-brown.

Habitat and Distribution

Scapania nemorosa can be found on moist rock ledges or cliffs, on rocks in streams, on moist rotting logs and loam or clay soil of banks.

It is widespread and abundant, with 156 records from 11 counties (Albert, Charlotte, Kent, Kings, Queens, Restigouche, Saint John, Sunbury, Victoria, Westmorland and York). Scapania nemorosa is the most common Scapania species in the province - represented by 55 primary and 48 associate taxon records at New Brunswick Museum. Other significant collections include the University of British Columbia (38), the Farlow Herbarium (5), and the New York Botanical Garden (6).
