Asplenium tutwilerae (Tutwiler’s spleenwort or Scott’s fertile spleenwort) is a rare epipetric fern found only in Hale County Alabama United States. A. tutwilerae is a fertile allotetraploid formed by the chromosomal doubling of a specimen of the sterile diploid A. × ebenoides a hybrid of A. platyneuron and A. rhizophyllum. Except for its spores which are fertile rather than malformed A. tutwilerae is essentially identical to A.
