polyrhiza, previously known from Amazonian Brazil, are recorded for the first time in Colombia. They
were found as epiphylls on understory shrubs in the middle Caquetá area in Colombian Amazonia.
Cololejeunea surinamensis was found in the Tierra Firme forests and D. polyrhiza was found in the
floodplains of the Caquetá River.

types of Colombian Amazonia, non-flooded tierra firme forest and floodplain forest of the Caquetá
River. A total of 109 bryophyte species were recorded from 14 0.2 ha plots. Bryophyte life forms and
habitats were analyzed, including the canopy and epiphylls. Bryophyte species did not show
significant differences between landscapes but mosses and liverworts were different and with opposite
responses balancing the overall richness. Independence test showed differences in both life form
and habitat use distribution between the two forest types with more fan and mat bryophytes species
in the floodplains, and more epiphytic liverworts in the tierra firme forest. Correspondence analysis
showed differences in the bryophyte species assemblage between the two forest types where they
may be responding to the higher humidity provided by the flooding. Despite of, the environmental
differences detected, epiphyll species assemblages were not strongly affected. Apparently, epiphyll
habitat is stressful enough to hide the environmental differences between the flooded and Tierra
firme forests.

We report the discovery in Colombia of the rare liverwort Bromeliophila helenae Gradst., a species previously known from only two localities, one in the Guayana Highland of Venezuela andthe other in the Lesser Antilles (Dominica). The oilbodies of the genus Bromeliophila are described for the first time. We also provide a description of the habitat of B. helenae and a comparison with the sister species B. natans (Steph.) R. M. Schust. founded in the Brazilian restinga.
