Discusión taxonómica
Trichipteris scabriuscula has been distinguished on the basis of heavily pubescent stipes, but this character is quite variable and, we think, unreliable. The hairs and bullate scales are similar to those of C. godmanii, but the blades of C. bicrenata are slightly less dissected.A
