The classifications of Bryophytes as given by G.M. smith.
Explanation:
G.M. smith classified bryophytes in three classes : Hepaticae, Anthocerotae and Musci.
Hepaticae: A class of Bryophyta comprising the liverworts and being distinguished from Musci by the presence of a usually thalloid gametophyte that is not produced from a protonema, unicellular rhizoids and elaters, and antheridia and archegonia that are borne on the thallus and produce a short-lived and simple sporophyte.
Anthocerotae: The Anthocerotae (hornworts) is one class of the Division Bryophyta (bryophytes) and consists of a single order, Anthocerotales, and a single family, Anthocerotaceae. The better known classes of the Bryophyta are the Musci (mosses) and Hepaticae (liverworts).
Musci : A class of Bryophyta comprising the mosses and being characterized by a well-developed leafy gametophyte that arises by budding from a protonema and bears sex organs among the leaves at its tip and by a sporophyte that develops from the fertilized egg, remains attached to the tip of the gametophyte, and is a naked usually stalked and operculate capsule in which asexual spores are borne.
