Key Identification Features
- vestitum are produced in round sori protected by round indusia, which is a characteristic feature of the Polystichum genus.
- A distinctive identifying feature is that the first pinnule closest to the main stem on the lowest pinna is shorter than the second pinnule.
- Many cultivars exist: over 300 cultivars have been described, though most are no longer in cultivation or are not considered sufficiently distinct to receive an individual name.
