|discussion=<p>Because of the always abundant gemmae on leaf apices, <i>Grimmia anomala</i> has often been confused with <i>G. hartmanii</i>. Indeed, it has frequently been treated as a variety of that species (G. N. Jones 1933; E. Lawton 1971). However, as pointed out by O. Vitikainen (1969), the ecological and morphological features of <i>G. hartmanii</i> are so constant and distinct that there is no doubt that it can be treated as a separate species. Special features of <i>G. anomala</i> are stems with central strands, and longitudinal ridges on cell walls in the distal part of the leaf that resemble papillae in transverse section. It tends to prefer upland habitats. In contrast, <i>G. hartmanii</i> is principally a lowland species, frequently growing on boulders in forests. It lacks a central strand, and longitudinal ridges are absent. Its spreading, secund distal leaves taper to long, sharply keeled apices.</p>
