Specialized asexual reproduction absent. Sporophytes absent in range of flora.

Discussion

Anoectangium stracheyanum was previously treated as a synonym of A. aestivum (R. H. Zander 1977), but further study indicates that it is a good match for the Asian A. stracheyanum, in the weakly wasp-waisted, narrow leaves with a rather strong, commonly multicellular apiculus, and papillose-crenulate or weakly denticulate basal laminal margins. The “wasp-waist” referred to by Asian authors is usually just a hint of constriction just beyond the short-sheathing leaf base, and many leaves are merely straight-sided. Collections from Maine identified as A. peckii are Amphidium mougeotii.
