Frond dimorphism refers to a difference in ferns between the fertile and sterile fronds.
 Since ferns, unlike flowering plants, bear spores on the leaf blade itself, this may affect the form of the frond itself.
 In some species of ferns, there is virtually no difference between the fertile and sterile fronds, such as in the genus "Dryopteris", other than the mere presence of the sori, or fruit-dots, on the back of the fronds.
 Some other species, such as "Polystichum acrostichoides" (Christmas fern), or some ferns of the genus "Osmunda", feature dimorphism on a portion of the frond only.
 Others, such as some species of "Blechnum" and "Woodwardia", have fertile fronds that are markedly taller than the sterile.
 Still others, such as "Osmunda cinnamomea" (Cinnamon fern), or plants of the family Onocleaceae, have fertile fronds that are completely different from the sterile.
Alonsoa (Mask flower) is a genus of 12 species of flowering plants in the family Scrophulariaceae, the figwort family.
 The genus includes both herbaceous and shrubby species.
Dryopteris crassirhizoma is a fern species in the genus "Dryopteris".
 It is an element (Traditional: 貫眾, Simplified: 贯众) of the Yupingfeng Asian soup formulation derivative.
Dryopteris , commonly called wood fern, male fern (referring in particular to "Dryopteris filix-mas"), or buckler fern, is a genus of about 250 species of ferns with distribution in Eastern Asia, the Americas, Europe, Africa, and the Pacific islands, with the highest species diversity in eastern Asia.
 Many of the species have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of fronds.
 The sori are round, with a peltate indusium.
 The stipes have prominent scales.
