Fissidens taylorii is characterized by the fertile (smaller) and sterile (larger) plant dimorphism, acute to subobtuse leaf apex, subpercurrent to percurrent costa, vaginant laminae 1/2-2/3 the leaf length, unistratose, smooth or slightly bulging, firm-walled laminal cells. This species was named in honor of Thomas Taylor (1775-1848), an Irish botanist, and collaborator with both J.D. Hooker and W.J. Hooker.
