“ Schweinitz and American Hepaticæ.— The paper which Schweinitz as a mycolologist, in the February Gazette, suggests his relation to the study of American Hepaticæ. Michaux was the earliest writer on this group, describing 13 species, five of which were new (Flora II, 276-280) , but Schweinitz published the first work devoted entirely to the hepatics. The work is now rarely seen, having been printed at Raleigh in 1821. Its full title is as follows: "Specimen Floræ Americæ Septentrionalis Cryptogamicæ sistens Muscos hue usque in Am. Sept. observatos." ”
