Publisher Summary The sole important development in fern cytological technique has been
the development of a variety of squash methods for the study of fern chromosomes in …

The main object of this paper is that of presenting a classification of all genera of the extant
Pteridophytes, based on the phylogeny. First, a new scheme of classification of the higher …

A new classification of Hymenophyllaceae, consisting of nine genera (Hymenophyllum,
Didymoglossum, Crepidomanes, Polyphlebium, Vandenboschia, Abrodictyum …

The percentage of pantropical and amphioceanic genera of ferns far exceeds similar
percentages for angiosperms. Conversely, the number of" endemic" fern genera is much …

The purpose of this study is to determine the floristic affinities of pteridophytes between the
neotropics and Africa-Madagascar and examine how these affinities might have arisen. We …

The “filmy fern” family, Hymenophyllaceae, is traditionally partitioned into two principal
genera, Trichomanes sl (sensu lato) and Hymenophyllum sl, based upon sorus shape …

Hymenophyllaceae is a fern family comprising around 450 species distributed among nine
genera. Genome size and chromosome number have been recurring research target for …

Among the basal fern families, the Hymenophyllaceae, with more than 600 species, display
a high diversity in terms of their morphology and the habitats that they occupy. We have …

We investigated the phylogenetic relationships of the filmy fern genus Hymenophyllum sl
using the rbcL and rps4 genes and the intergenic spacer rps4-trnS. Because of variation in …

Floras serve as the basic reference of the plant biota of an area; they are critical tools that
serve botanists, conservationists, ecologists, foresters, gardeners, agronomists, researchers …
