These characteristics, combined with its ancient divergence, suggested it had been evolving independently from other Radula species for a very long time. The recognition of Dactyloradula as a separate genus brought the total number of genera in the family Radulaceae to three, alongside Radula and Cladoradula. [3]

The species was long classified in the genus Radula within subgenus Cladoradula. In 2022, Renner and colleagues conducted a molecular phylogenetics study that revealed the subgenus Cladoradula represents one of the oldest lineages within the family Radulaceae, having diverged from other members during the late Permian period.

Endemic to Macaronesia, this dark to olive-green liverwort is known from five locations on Madeira Island and one location on Tenerife, where it grows as both an epiphyte on trees such as Laurus novocanariensis and as a lithophyte on shaded ...
