|discussion=<p>The disjunction of <i>Campylopus tallulensis</i> from southeastern North America to Mexico, which is also met in other bryophytes and flowering plants, is considered to be a result of a former continuous range in the Tertiary. <i>Campylopus tallulensis</i> was included in <i>C. flexuosus</i> by American authors. There is a superficial similarity regarding the habit and the shape of the distal laminal cells. <i>Campylopus flexuosus</i> is, however, easily distinguished by thick-walled basal laminal cells and the presence of microphyllous brood branches. Plants of <i>C. tallulensis</i> from Mexico and eastern North America are robust and yellowish to golden green. In contrast, the specimens collected in Illinois, Mississippi (in part), and Arkansas are more slender and dark green, resembling <i>C. subulatus</i> in appearance. It is not known whether these differences in color depend on a different geological substrate or are the expression of different populations. Both species are anatomically very similar with thin-walled hyaline basal laminal cells, almost quadrate distal laminal cells, a costa excurrent in a sometimes subhyaline point and being roughened at the abaxial side like a rat’s tail file and a channeled leaf apex. The only way to distinguish both species seems to be the transverse section of the costa, which shows very distinct groups of abaxial stereids in <i>C. tallulensis</i> but no abaxial stereids in <i>C. subulatus</i>. Furthermore, the adaxial hyalocysts of <i>C. tallulensis</i> are twice as wide as those of <i>C. subulatus</i> (J.-P. Frahm 1994). On the basis of this character, the only records of <i>C. subulatus</i> in North America from California belong to this species and are not extensions of the range of <i>C. tallulensis</i> from Mexico.</p>
