Basionym.
Scapania subsect. Simmonsia [" Simmonsiae "] R.M. Schust., Hepat. Anthocerotae N. Amer. 3: 612. 1974.
Type.
Scapania simmonsii Bryhn & Kaal., Rep. Second Norweg. Arctic Exped. Fram 2 (11): 51. 1906.
Note.
Scapania simmonsii forms an isolated lineage within S. subg. Scapania , hence, we erect a section for this species rather than using subsectional rank ( Schuster 1974). Distinctive features of the monotypic section are the deflexed-involute, broad, concave ventral leaf lobes that stand away from the stem at almost right angles and leaf cell walls with very large, nodulose trigones.
