Abstract

Gastony’s Cliffbrake (Pellaea gastonyi Windham) is a globally rare fern (Pteridaceae) that grows on limestone cliffs and ledges, including those associated with alvars. Until now, the only record in Manitoba was from a location just north of Fisher Branch. We report additional records and locations, one of which is over 250 km north of the initial collection. We also provide a conservation status assessment of this species in Manitoba that indicates that this species is rare in the province and is threatened in at least a portion of its range by habitat loss and degradation.
