Abstract A taxonomic revision of the Old-World representatives of the fern genus Orthiopteris is presented. We recognize eight species, one of which is newly described (Orthiopteris samoensis), and five varieties, of which two are newly described (Orthiopteris campylura var. insularis and Orthiopteris campylura var. laxa). Orthiopteris acuminata, Orthiopteris caudata, Orthiopteris minor and Orthiopteris kingii are all reduced to varieties of Orthiopteris campylura.

A fossil species of the enigmatic early polypod fern genus Cystodium (Cystodiaceae) in Cretaceous amber from Myanmar
The fossil strengthens the hypothesis that the forest ecosystems of Malesia and Melanesia represent refugia for many tropical plant lineages that originated in the Cretaceous.


A linear sequence of extant families and genera of lycophytes and ferns
A linear classification to the extant lycophytes and ferns based on current phylogenetic knowledge is provided, which provides a standardized guide for organisation of fern collections into a more natural sequence.
On Some Pteridophytes of Sayap-Kinabalu Park, Sabah
A total of 142 specimens of fern and fern-allies were collected during the Sayap-Kinabalu expedition. They were identifted to 24 families, 59 genera, 106 species and 6 varieties including ten species
A classification for extant ferns
We present a revised classification for extant ferns, with emphasis on ordinal and familial ranks, and a synopsis of included genera. Our classification reflects recently published phylogenetic
Hierarchical Analysis of Allozymic and Morphometric Variation in a Montane Herb, Ipomopsis aggregata (Polemoniaceae)
Sixteen new sequences of the chloroplast gene rbcL were used to assess evolutionary relationships in Dennstaedtiaceae, and the following phylogenetic patterns were evident from maximum parsimony and maximum likelihood analyses.
Phylogeny and evolution of ferns (monilophytes) with a focus on the early leptosporangiate divergences.
The phylogenetic structure of ferns (= monilophytes) is explored here, with a special focus on the early divergences among leptosporangiate lineages. Despite considerable progress in our
Diversification of lindsaeoid ferns and phylogenetic uncertainty of early polypod relationships
Based on relaxed molecular clock analyses, it appears that the crown group lindsaeoids diversified in the Caenozoic, more or less simultaneously with the main radiation of other Polypodiales, even though the original divergence between the lindSaeoid and non-lindsaioid polypods occurred before the end of the Jurassic.
Utility of a large, multigene plastid data set in inferring higher-order relationships in ferns and relatives (monilophytes).
The utility of this plastid-based data set in corroborating relationships found in previous studies, improving support, and resolving uncertainties in monilophyte phylogeny is supported.
Fern phylogeny inferred from 400 leptosporangiate species and three plastid genes
The scope of the analysis provides unprecedented insight into overall fern relationships, not only delivering additional support for the deepest leptosporangiate divergences, but also uncovering the composition of more recently emerging clades and their relationships to one another.
