Lindsaea linduensis (Lindsaeaceae, Polypodiales), a new fern species from Sulawesi, Indonesia
Phytotaxa, 2012Lindsaea linduensis (Lindsaeaceae), from Central Sulawesi, Indonesia, is described as new to science. It differs from L. repens var. sessilis by having 2-pinnate fronds (versus 1-pinnate), longer petioles (10–17 cm versus 1–5 cm), and more widely spaced ultimate segments (>5 mm apart versus <4 mm).

The fern family Blechnaceae, with about 250 species, has traditionally comprised one large genus, Blechnum, plus seven to nine smaller genera, most with fewer than 10 species. Several phylogenetic analyses strongly suggest that Blechnum in the traditional sense is not a monophyletic group.

Pteridryaceae: A new fern family of Polypodiineae (Polypodiales) including taxonomic treatments
Journal of Systematics and Evolution, 2018AbstractWe undertook phylogenetic analyses to resolve the relationships of Pteridrys and related taxa based on six plastid markers (atpA, atpB, matK & rps16‐matK, rbcL, rps4 & rps4‐trnS, and trnL & trnL‐F) and nuclear pgiC. We included 195 accessions representing approximately 147 species in 38 genera, and seven of the nine families in ...

Systematics of the Leptochilus macrophyllus complex (Polypodiaceae, Polypodiales)
Botanical Journal of the Linnean SocietyAbstract Leptochilus is an Old World fern genus with uncertain species diversity. The Leptochilus macrophyllus complex exemplifies this uncertainty, as previous taxonomic treatments recognized it as a broadly circumscribed species with considerable morphological variation.

Asplenium pifongiae (Aspleniaceae: Polypodiales), a New Species from Taiwan
Systematic Botany, 2016Abstract We describe and illustrate a new species, Asplenium pifongia., currently known only from Taiwan. Although superficially similar to A. monanthe., this species is a sexual diploid and has little perforation on its spore surfaces. Phylogenetic analyses demonstrate that A. pifongia. is not closely related to A.
