The greatest confusion exists among the older authors between this 

 species and the next, and even Huebener, C. Mueller and others who adopt 

 G. commutata quote Hedwig's Dicranum ovale as a synonym of it, in spite of the 

 beautiful 5-lobed calyptra figured on his plate. It is clear that G. ovalis 

 (Hedw.) must stand for G. ovata of most modern authors, and that G. ovata 

 Web. Mohr — collected by them at Carlbergs Allee, Stockholm, although they 

 do not appear to have seen the calyptra — is not the same as Hedwig's ovalis, 

 but the type of G. commutata Hueben. as was suspected by Zetterstedt, and 

 more expressly indicated by Lindberg, who remarks that G. commutata is 

 abundant about Stockholm, but G. ovalis is scarcely found there, and Weber 

 and Mohr's description of their G. ovata " capsula ovata, pedunculo brevi insidente, 

 opereulo oblique rostrato, per. denies 16, latiuscuU," is far more applicable to G. com- 

 mutata than to Hedwig's G. ovalis. It is evident then that the original names 

 of the two species, characterized clearly enough when they were established, 

 should be restored, and all the cross references of one to the other had better 

 be avoided. G. ovata is distinguished by the dioicous infl., taller stem with 

 more distant leaves, opake in the upper part, and with very narrow 

 elongated cells near the basal part of the nerve, inflated caps, with long 

 oblique acute beak, cucullate calyptra, and broad trifid teeth of peristome.
