The species is distinguished from the similar P. calirhiza by the long -attenuate tips of the pinnae, round sori, and free veins. P. calirhiza usually (but not always) has at least some anastomosing veins. P. glycyrrhiza prefers more shade and damper sites, as seen here.

The main plant with the upright central fronds is Polystichum dudleyi. Above this across the top of the image are fronds of Polystichum munitum, and at the lower right (and also near the top just below the P. munitum) are fronds of Polystichum californicum. These fronds are less divided than those of P. dudleyi, reflecting that P. californicum is a hybrid species formed from P. dudleyi and P. munitum.
