“…Our present datasets of rps4, trnL-F, and nad5 do not contain enough information to elucidate the relationships the terminals recognized as members of the Daltoniaceae sensu Pokorny et al (2012). Except for some terminal pairs of genera, only two clades can be distinguished as monophyletic with high support values.…”

“…Bryobrothera inferred from the small date set of rps4, trnL-F, and nad5 sequences. Two Ephemeropsis species are attributed as outgroup terminals of these three genera on the basis of results presented by Ho et al (2012) and Pokorny et al (2012). Scale bar indicates base substitution.…”

“…Pokorny et al (2012) already showed the monophyly of these elimbate Daltoniaceaous genera on the basis of five gene molecular analyses. As for morphology and habitat preference, the Sabah plants and the two genera share the following features; (1) growing on trunks and branches of small trees in mossy montane forests, (2) more or less flat foliation in aerial shoots, (3) leaves with distinctly narrowed bases, (4) narrow but clearly differentiated alar regions with quadrate, pitted cells, (5) fusiform and distinctly porose lower laminal cells, (6) quadrate to short-rectangular, thick-walled upper laminal cells, and (7) single, thick costa reaching more than 4/5 of leaf length.…”

“…To better understand the relationships of Benitotania elimbata, Adelothecium bogotense (Hampe 1866: 303) Mitten (1869: 391), Bryobrothera crenulata (Brotherus & Paris 1908: 19) Thériot (1921: 26), and the Sabah plant, additional analyses were performed with a small dataset containing Ephemeropsis tjibodensis Goebel (1892: 116) and E. trentepohlioides (Renner 1934: 88) Sainsbury (1951: 2) as outgroup terminals following the results obtained by Pokorny et al (2012) and Ho et al (2012).…”

We report a new species Bryobrothera tambuyukonensis, based on the specimens collected in Sabah, Borneo Island. Phylogenetic analyses with plastid (rps4 and trnL-F) and mitochondrial (nad5) genes along with a number of morphological features (for example, undulate lamina, oblong-lanceolate leaves with a single strong costa reddish brown in color, and thickwalled and porose laminal cells) confirmed its distinctiveness from B. crenulata and also close relationship to the elimbate group comprised of Adelothecium bogotense and Benitotania elimbata.

“…(Buck et al, 2005;Cox et al, 2010) which allows further evaluation of evolutionary trends within the group. Pokorny et al (2012) resolved intraordinal relationships, tested conflicting traditional systematic concepts (gametophytic versus sporophytic) and explored the evolution of gametophytic and sporophytic characters in the Hookeriales. Their work confirmed that sporophytic characters are at least as prone to convergent evolution as are gametophytic ones (compare Vanderpoorten et al, 2002;Huttunen et al, 2004;Quandt et al, 2009).…”

The Hypnodendrales are an order of generally very robust pleurocarpous mosses in which most taxa have one of three distinct growth forms. The group includes four monotypic genera, two of which, Cyrtopodendron and Franciella, are endemic to New Caledonia. We investigate the phylogenetic relationships of these two taxa and of Pterobryella rigida, also a New Caledonian endemic, and demonstrate that Cyrtopodendron and Franciella should be recognised within Pterobryella and Spiridens respectively as P. vieillardii and S. spiridentoides. We further use Bayesian methods to reconstruct ancestral character states for macro–morphological type and substrate preference within the order, to evaluate hypotheses of correlated evolution of these morphological and ecological characters, and to test for directionality in their evolution. The results suggest that macro–morphology evolves in conjunction with shifts between epiphytic and non–epiphytic substrates, with the dendroid architecture strongly associated with non–epiphytic substrates and the morphologies we term “stipitate–frondose” and “spiri–dentoid” associated with epiphytism. Ancestral character state reconstruction challenges previous hypotheses that the strictly dendroid form is plesiomorphic within the Hypnodendrales and suggests that the stipitate–frondose architecture may have arisen very early within the evolution of the group, although states for the earliest nodes remain ambiguous. The spiridentoid growth form characteristic of Spiridens, Cyrtopus and Bescherellia may be inherited from a shared common ancestor, with the dendroid morphology of Hypnodendron s.str. being derived, while within Pterobryella the balance of evidence favours an epiphytic, stipitate–frondose common ancestor from which the lithophytic species found on New Caledonia and Lord Howe are descended. Transitions between the major growth forms found within the order are highly homoplastic, facilitating adaptive shifts between epiphytic and non–epiphytic substrates and explaining the paraphyly of some previously recognised genera and families.The Hypnodendrales are an order of generally very robust pleurocarpous mosses in which most taxa have one of three distinct growth forms.
