    Asplenium flabellulatum is part of the A. radicans complex, a group having castaneous, lustrous stipes and long-flagelliform, proliferous blade tips. We no longer maintain var. partitum as distinct from var. flabellulatum, as was done by Smith (1981) and Adams (in Davidse et al., 1995). Some of the collections cited by Mickel and Beitel (1988) as A. uniseriale (e.g., Mickel 1080) are A. flabellulatum. For additional discussion, see under A. radicans.
