Hedwig made very fine detail examination of moss capsules as seen in the plates. II but without vignette. This is a scarce work on the classification of mosses. Hedwig was a German physician and professor of botany in Leipzig who was an authority on mosses and founder of the field of Bryology, study of mosses. The moss genus Hedwigia is named after him. Hes know to have collected plants in the morning before visiting patients and then working on these specimens in the evening.
