The Liverworts and Hornworts of Belize

A complete list of the liverworts and hornworts known from Belize, comprising 49 genera and 65 species, is presented. Twenty-two genera and 30 species are new to Belize, and Calypogeia lophocoleoides Steph. is new to Central America. Belize is a small country (22,963 square km) lo- cated on the Caribbean coast of northern Central America at approximately 160 to 181/20 north lati- tude. The northern half of the country is a low-lying limestone plain, while the southern half is domi- nated by the Maya Mountains, a raised peneplain reaching 1,140 m elevation at Doyles Delight. The Maya Mountains may once have formed part of a land connection between northern Central America

Cronisia and its two species, C. fimbriata and C. weddellii

Abstract The systematic position of Riccia fimbriata Nees, a species formerly known only in sterile condition and tentatively placed in the genus Exormotheca, is reexamined in the light of the recently discovered reproductive structures. The species proved to be a member of the genus Cronisia, identical to Cronisia mexicana Hicks, described in 1993. A key is provided to the two known species of Cronisia, C. fimbriata and C. weddellii, and they are described and illustrated.
