Throughout the history of the classification of extant ferns (monilophytes) and lycophytes,
familial and generic concepts have been in great flux. For the organisation of lycophytes and …

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 …

In an effort to obtain a solid and balanced approximation of global fern phylogeny to serve
as a tool for addressing large‐scale evolutionary questions, we assembled and analyzed …

Over the past 70 years, many fern classifications, nearly all based on morphology, most
explicitly or implicitly phylogenetic, have been proposed. The most complete and commonly …

Tree ferns are a well-established clade within leptosporangiate ferns. Most of the 600
species (in seven families and 13 genera) are arborescent, but considerable morphological …

石松类和蕨类植物是以孢子繁殖的维管植物, 在陆地植物演化上占据重要地位.
随着分子系统学研究的开展, 各大类群间的系统发育关系得以阐明, 传统上的概念得以修正 …

We describe the neotropical fern genus Serpocaulon (Polypodiaceae), segregated from
Polypodium, and make new combinations for the forty known species. Serpocaulon has …

Noncoding DNA sequences from numerous regions of the chloroplast genome have
provided a significant source of characters for phylogenetic studies in seed plants. In …

The polygrammoids (Polypodiaceae) are the most species‐rich and diversified epiphytic
fern lineages, and hold an important role to understand the deep diverging events and rapid …

The genus Platycerium is one of the few pantropical epiphytic fern genera with six species in
Afro‐Madagascar, 8–11 Australasian species, and a single species in tropical South …
