Similar Species
Polystichum lemmonii and Polystichum kruckebergii are related taxa which are morphologically and ecologically similar to Polystichum scopulinum. P. scopulinum can be distinguished from P. lemmonii by its spiny-toothed pinna margins and its once pinnate fronds (vs. smooth margins and bipinnate fronds in P. lemmonii) (Douglas et al. 2000). P. kruckebergii has once pinnate fronds like P. scopulinum, but the pinnae are abruptly pointed (especially at the base of the frond) and bear coarse, spreading teeth. P. scopulinum has pinna tips that are obtuse and bear fine incurved teeth.
