Annales Bryologici: a Year-Book devoted to the Study of Mosses and Hepatics

Nature volume 135, page 288 (23 February 1935) | Download Citation



A SKETCH of the progress of hepaticology occupies the first thirty-six pages; a knowledge of early authors is considered essential in questions of nomenclature and in dealing with types of genera; Evans, Howe, Lindberg, Schiffner and Spruce are authors favourably mentioned, but Stephani's “Species Hepaticarum“is very frankly criticised; its errors and other faults are considered to be so grave, that setting it aside as “opus excludendum“is discussed; in view however of its wide acceptance, that course is inexpedient and revision is recommended. Improved methods, geographical, cyto-logical, genetical, experimental morphological, etc., are urged in the study of liverworts; the weakness of much recent bryological literature is referred to. Revision is the most urgent need of to-day; progress will largely depend on the study of the smaller groups, which are insufficiently understood.
