ICONES MUSCORUM.
Our plant is the only representative at present known, within our limits, of Macromitrium, mostly a tropical and subtropical genus, abounding in species.
Since the engraving of Plate 37, we find that C. Müller (Bot. Zeit. 1862, p. 361) considers the Georgian Moss to be different from M. Dregei, Hornsch., and proposes for it the name of M. Sullivantii.
