Discussion
As with Weissia ludoviciana, the gametophyte of W. muehlenbergiana is like that of W. brachycarpa, but differs to some extent in the distal leaf margins occasionally sharply inflexed. If the sporophyte has a hybrid origin, then the archegoniate parent has characteristics of both W. controversa and W. brachycarpa. The hybrid W. muehlenbergiana × W. controversa was reported by C. Williams (1966).
