Abstract: -(Vegetative reproduction patterns in species of Lejeuneaceae (Marchantiophyta) and its taxonomic and ecological significances). The study of the vegetative reproduction of 33 infrageneric taxa of Lejeuneaceae from the State of Bahia (Brazil) allowed the identification of six basic patterns of the vegetative reproduction process: (a) cladia; (b) leaves fragmentation; (c) regenerates; (d) caducous leaves; (e) gemmae; (f) semi-caducous underleaves. The employment of the vegetative reproduction patterns to evalua… Show more

“…Among the liverworts this behavior allows quick occupation of the substrates, particularly on epiphytes, since the presence of numerous gemmae enable the species to spread vegetatively and establish on the vertical substrates, increasing their survival chances (Glime 2007, Bastos 2008. It is believed that the vegetative reproduction processes are a safe strategy for the production of new individuals, considering the diffi culties that may prevent the sexual process (Laaka-Lindberg 2000).…”

“…From the species list, a species character matrix was built for 104 species of Lejeuneaceae, with records of the following: presence of dark pigmentation, ability to convolute leaves when dry, possession of thickened cell walls, reproduction mode (monoicous or dioicous), occurrence of asexual reproduction and epiphyllous habit. All traits were scored as present (1) or absent (0) at species level, and reproductive system as monoicous (1) or dioicous (0) (or both, 0-1, in four species), based mainly on taxonomic literature ( Bastos, 2008 ; Bastos, 2017 ; Bernecker-Lücking, 1998 ; Bischler, 1967 ; Bischler, 1969 ; Dauphin, 2003 ; Gradstein, 1994 ; Gradstein, 1997 ; Gradstein & Costa, 2003 ; He, 1999 ; Ilkiu-Borges & Gradstein, 2008 ; Ilkiu-Borges & Lisboa, 2004 ; Jovet-Ast, 1953 ; Piippo, 1986 ; Reiner-Drehwald, 1995 ; Reiner-Drehwald, 2009 ; Reiner-Drehwald & Goda, 2000 ; Schuster, 1980 ). A few cases interpreted as doubtful by the author were scored with an X, and the species was excluded from the analysis of that trait.…”
