We determined the sequence of the region of the chloroplast DNA inverted repeat spanning from the 3'-terminus of the 23S rRNA gene to the 5'-terminus of the tRNA[Arg](ACG) gene (about 700 bp) from 25 bryophytes and from the charophycean alga Chara australis. Phylogenetic analysis of these sequences using the neighbor-joining method suggests an early dichotomy of bryophytes and their paraphyly r...
On the diversity and richness of understory bryophytes at Nectandra Cloud Forest Reserve, Costa Rica
BACKGROUND A survey of the understory bryophytes in the Nectandra Cloud Forest Preserve yielded 1083 specimens distributed among 55 families, represented by 74 genera of mosses, 75 genera of liverworts and 3 of hornworts. We studied and analyzed the bryophytic distribution on six types of substrates: 1) corticolous, 2) epiphyllous, 3) saxicolous, 4) terricolous, 5) aquatic and 6) lignicolous. T...
The current issue of Phytotaxa is dedicated to a group of green land plants commonly referred to as bryophytes. A broad consensus confirms that bryophytes may not be monophyletic, but rather represent three paraphyletic lines, i.e., Marchantiophyta (liverworts, e.g., Fig. 1), Anthocerotophyta (hornworts, e.g., Fig. 2), and Bryophyta (mosses, e.g., Fig 3) (e.g., Mishler & Churchill 1984, Kenrick...
In contrast to the highly variable mitogenomes of vascular plants, composition and architecture within three bryophyte lineages appear stable invariant. Currently, complete are available from 113 accessions 71 genera 28 orders. Liverworts mosses hold a rich mitochondrial (mt) gene repertoire among land plants with 40–42 protein-coding genes, whereas hornworts maintain smallest functional set on...
There have been more than 640 species of bryophytes recorded for Tasmania, comprised of 282 hepatic species (Ratkowsky 1987) and 361 moss species (Dalton et al. 1991). This number of species is significant when compared to other groups ofland plants and, therefore, the bryophytes represent a major component of the flora (table 1). Since the publication of an annotated checklist of Tasmanian mos...
