Abstract

Athyrium puncticaule is recorded for the first time from Taiwan. Most specimens of this species deposited in Taiwanese herbaria have been misidentified as Athyrium anisopterum. It can be distinguishable by densely covered unicellular hairs on the fronds and morphology of pinnae. The authors present a description, illustration, photographs and notes about this new addition to the Taiwanese fern flora and its distinction from other species.
