Frullania tamarisci


Frullania tamarisci is a common leafy-liverwort in New Brunswick. As with other Frullania species, it is distinguished from other liverworts by the incubus leaf orientation and uniquely complicate-bilobed leaf pattern, in which the ventral lobes form small sac-like appendages with the openings at the posterior margin. In addition, F. tamarisci has a line of opaque cells (ocelli) on the dorsal leaf lobes. The plants are typically red/brown or a deep, dark green.

Habitat and Distribution

Frullania tamarisci can be found on dry granite cliffs or occasionally on bark of deciduous and coniferous trees and on rotting logs.

There are 90 records of Frullania tamarisci in New Brunswick throughout 11 counties: Albert, Carleton, Charlotte, Kent, Kings, Northumberland, Queens, Restigouche, Saint John, Westmorland and York.

It is widespread and common, a generalist species of habitats that fluctuate in moisture levels. 50 records are from the New Brunswick Museum (most as primary taxa). The Herbaria at the University of British Columbia and Duke University also have significant holdings, with 20 and 10 records reported, respectively.
